Water conservation and purification are crucial for ensuring the health and

well-being of individuals and communities worldwide. With the increasing

demand for clean water and the growing threat of water scarcity, innovative
technologies are being developed to address these challenges. Here are
some of the most promising innovative technologies for water conservation
and purification:

1. Photocatalytic Water Purification

Photocatalytic water purification uses photocatalyst and ultraviolet rays

to remove toxic substances and contaminants from water at high speeds.
This technology is cost-effective, sustainable, and has been shown to be
effective in removing a wide range of pollutants, including pesticides,
microbes, viruses, and dyes.

2. Solar Absorber Gel

Researchers at Princeton University have developed a Solar Absorber

Gel that can purify water using solar energy. The gel absorbs water at room
temperature, changes shape when heated, and releases the purified water.
This technology has the potential to provide clean water to communities
worldwide.

3. Desalination Technologies

Desalination technologies are being developed to make saltwater usable for

human consumption and agriculture at a lower cost and with less
environmental impact than traditional methods. New technologies, such
as reverse osmosis and membrane distillation, are being developed to
improve the efficiency and sustainability of desalination.

4. Nanotechnology-Based Water Purification

Nanotechnology is being used to develop innovative water purification

systems that can remove contaminants at the molecular level. Carbon
nanotubes, for example, can remove organic, inorganic, and biological
compounds from water, making it safe for drinking.

5. Bioaugmentation

Bioaugmentation is a technology that uses microorganisms to break

down and remove contaminants from wastewater. This technology has
the potential to transform wastewater into drinking water and reduce the
amount of pollutants released into the environment.

6. Acoustic Nanotube Technology

Acoustic nanotube technology uses sound waves to drive water through

carbon nanotubes, removing contaminants and purifying the water. This
technology has the potential to be used in a variety of applications,
including wastewater treatment and drinking water purification.

7. Automatic Variable Filtration (AVF)

AVF is a water purification technology that uses a simple, cost-effective, and

energy-efficient system to remove contaminants from water. This
technology is suitable for wastewater treatment, municipal drinking water,
and pre-filtration and desalination uses.

8. Smart Water Solutions

Smart water solutions, such as monitoring systems, leak detection, and

automated shutoff valves, can significantly reduce water waste by
enabling active management and immediate response. These technologies
are leading the charge against the global water crisis.

9. Rainwater Harvesting

Rainwater harvesting systems are being developed to collect and store

rainwater for non-potable uses, reducing the demand on municipal water
supplies and promoting sustainable water management.

10. Innovative Desalination Technologies

Innovative desalination technologies, such as forward osmosis and

membrane distillation, are being developed to improve the efficiency and
sustainability of desalination. These technologies have the potential to
make saltwater usable for human consumption and agriculture at a lower
cost and with less environmental impact than traditional methods.

These innovative technologies have the potential to revolutionize the way

we conserve and purify water, ensuring a sustainable future for generations
to come.

1. Solar-Powered Water Filtration

Researchers at Princeton University developed a Solar Absorber Gel

people can apply to contaminated water3. This solar gel absorbs
water at room temperature, but it changes shape and releases the
water when heated. It has a second layer consisting of
polydopamine, which can transform the sun’s energy into heat. The
third layer is made of alginate.

When water passes through the gel, it purifies by filtering out

pathogens, metals, and other molecules from the water. The device
uses a passive gravity-based filtration method. As a result, it only
requires power from the sun to work properly. Additionally, the
device can deliver clean water much more quickly than some of the
other advanced water treatment technologies.

2. Desalination Systems

The desalination process is highly popular, especially in countries in

the Middle East. In the desalination process, salt from saltwater is
extracted to obtain freshwater, which can be used for several
purposes. Current desalination processes are energy-intensive, but
recent advancements have led to significant reductions in energy
consumption.

One method researchers and engineers have used to decrease

energy usage is increasing the size of the membranes used to
desalinate water.4 Instead of using 8-inch membranes, desalination
plants use 16-inch membranes with smaller pores and four times the
active area. This lowers the cost of operating and maintaining the
treatment plant while increasing the amount of water processed.

3. Nanotechnology

Countries can use various nanotechnology-based water purification

systems as cost-effective, efficient solutions to provide water for
those who need it. Nanotechnology can remove contaminants in
water efficiently to increase the availability of water. In simple
terms, it manipulates the atoms in water on a molecular level.
Nanotechnology can assist with several water purification
processes, including:

 Desalination
 Filtration
 Remediation
 Water treatment

One of the most common water purification techniques in the

nanotech space is the carbon nanotube (CNT).5 CNT-based filtration
systems remove organic, inorganic, and biological compounds from
water to make it safe for drinking.

4. Bioaugmentation for Wastewater Treatment

It is well-known that wastewater is a significant source of water

pollution. Not only can wastewater treatment result in synthetic
fertilizer for the agriculture industry,6 but it can transform into
drinking water for consumption. One of the most popular methods of
treating wastewater is bioaugmentation. With this technology,
scientists introduce a mix of microorganisms to the liquid, which
breaks down and removes any contaminants.

The microorganisms typically consist of enzymes and certain types

of safe bacteria that degrade pollutants like oils or carbon
substrates.7 However, the scientists must implement a multi-step
process during bioaugmentation — they must safely remove the
microorganisms after they treat the wastewater.

5. Acoustic Nanotube Tech

NASA first developed acoustic nanotube technology, which served

as a solution for treating and recycling wastewater in the
International Space Station. However, the technology has various
purposes here on Earth. Rather than pressure pushing contaminants
out of water, this technology relies on acoustics to drive water
through carbon nanotubes.

Carbon nanotubes are placed within a filter matrix, where water

molecules pass through and contaminants stay behind. The acoustic
system uses an oscillator circuit to generate an acoustic vibration,
which encourages the water molecules to de-bond and move
through the filter for purification.8

6. Photocatalytic Water Purification

Another type of tech that helps provide people with water is

photocatalytic water purification. The technology uses photocatalyst
and ultraviolet rays to rid water of toxic substances and
contaminants at high speeds.

Photocatalysis with mild conditions is a simple process and is

considered a green technology, making it cost-effective and
sustainable.9 The process can take water and remove substances
such as pesticides, microbes, viruses, dyes, crude oil, and more.

7. Automatic Variable Filtration

Automatic variable filtration (AVF) is a water purification technology

that is relatively simple yet effective — it works when an upward
flow of influent is cleaned through a downward flow of filter media.
One of the most significant benefits is the water does not require
additional filtration or cleaning.

The AVF method does not have any moving parts or require power,
which makes it a cost-effective and energy-efficient system. The tech
is suitable for wastewater treatment and reuse, municipal drinking
water, and pre-filtration and desalination uses. Till here
 Leveraging Water Sanitation Systems to Improve the Freshwater
Crisis

As mentioned earlier, water is an essential aspect of life, yet a growing

number of people do not have regular access to it. Because the water
crisis is becoming such a concern for countries worldwide, global
companies are trying to find innovative ways to treat water for sanitation
and hygiene purposes.

The issues of climate change and rapid population growth are only going
to exacerbate the clean water crisis, therefore requiring more innovation
in this field. Continue monitoring what new technologies emerge to help
with wastewater treatment, sanitation, and hygiene, and how they
ultimately help people live more comfortably.

As you scan the horizon, the future of water scarcity looms large. According to the
World Health Organization, two-thirds of the world’s population may face water
shortages by 2025. While this is an alarming statistic, researchers and innovators
around the globe are developing technologies to help mitigate and overcome this
impending crisis. From advanced desalination techniques and smart irrigation
systems to portable water filters and leak detection devices, new tools are emerging
that can have a real impact. By embracing innovative water technologies solutions
for clean water , communities and countries can bolster conservation efforts,
improve infrastructure, increase access to clean water, and ensure adequate supply
for generations to come.
Progress is being made, but continued investment and implementation of these
groundbreaking technologies will be critical to changing the tide in the fight
against water scarcity worldwide. The future is unwritten, and with science and
technology on our side, there is opportunity to make a difference.

The Growing Global Water Crisis

The world is facing an unprecedented global water crisis. According to the United
Nations, over 2 billion people currently live in water-scarce areas, and that number is
expected to rise due to increasing demands from population growth and
industrialization. Lack of access to clean water leads to the deaths of nearly 1 million
people each year from waterborne diseases.
Solutions To Clean Water
Governments, nonprofits, and private companies alike are working to find solutions
to clean water<span style=”font-weight: 400;”> through emerging technologies
and innovative programs. Desalination, the process of removing salt and minerals
from seawater to make it drinkable, has become more efficient and affordable. Drip
irrigation and precision agriculture help farmers optimise water usage. Public
education campaigns teach communities how to practise water conservation and
sanitation.
While no single solution can solve the crisis, coordinated global action across sectors
can make a difference. Here are a few of the most promising innovations leading the
charge:
1. Solar-powered desalination uses renewable energy to convert seawater into
freshwater for drinking and irrigation. Several new desalination technologies can now
run on solar energy, a sustainable solution for water-scarce regions.
2. Wastewater treatment and reuse turns sewage and graywater into usable water for
agriculture or industrial use. As water recycling gains wider adoption, communities
can achieve greater water security and independence.
3. Leak detection systems use smart sensors and AI to identify leaks in water
infrastructure. By reducing loss from leaks and pipe bursts, utilities can save millions
of gallons of water each year and lower costs.
4. Water ATMs provide affordable, metered access to purified water in underserved
areas. The automated systems help address the unsafe drinking water crisis
impacting billions of people worldwide.
With global cooperation and the help of today’s brightest minds, we can work to
overcome dire projections and build a water-secure future for all. The technologies
and programs leading the charge offer hope that a solution for access to clean
drinking water may be within our reach.
What are Solutions to the Water Crisis ?
Here are some Desalination technologies that can help to cope with the water crisis.
Desalination uses specialised equipment, known as desalination plants or
desalination systems, to remove salt and other minerals from seawater or brackish
water to produce freshwater that is suitable for drinking or irrigation. .
Reverse Osmosis
The most common desalination method is reverse osmosis. Reverse osmosis
systems use high-pressure pumps to push seawater through semi-permeable
membranes that allow water to pass through but block salt and other contaminants.
Reverse osmosis requires significant energy to generate the necessary high
pressures but advancements are making the technology more efficient and cost-
effective.
Distillation
Distillation has been used for centuries and mimics the natural water cycle. Seawater
is boiled and the resulting water vapor is condensed into distilled water, leaving the
salt and other impurities behind. Although simple in concept, distillation requires
large amounts of energy to boil the seawater. Multiple-effect distillation and vapor-
compression distillation improve efficiency but high costs remain a barrier.
Emerging Water Technologies
Researchers are developing other innovative desalination technologies, including:
 Membrane distillation: Uses heat and semi-permeable membranes to separate
freshwater from seawater. Shows promise for lower energy usage.
 Forward osmosis: Relies on an osmotic pressure gradient to draw water through a
membrane, leaving contaminants behind. Still in early research and development.
 Capacitive deionization: Uses an electrical field to remove ionized particles from
water. Provides an energy-efficient approach but requires further refinement.
With populations rising and freshwater sources under threat, continued innovation in
desalination and other water treatment technologies will be critical to meet
increasing global demand. By improving efficiency and affordability, emerging
desalination technologies can help address water scarcity on a massive scale.
Efficient Irrigation Systems to Reduce
Agricultural Water Usage
Efficient irrigation systems are crucial to reducing agricultural water usage and
conserving our limited freshwater resources. As population growth continues to
strain available water supplies, improving irrigation efficiency is vital.
Drip Irrigation
The Drip irrigation, also known as micro irrigation or trickle irrigation, is one of the
most efficient irrigation methods. Drip irrigation systems deliver water slowly and
directly to the roots of plants through a network of valves, pipes, tubing, and
emitters. This targeted application minimises water loss from evaporation and runoff,
allowing farms to use up to 50% less water than conventional flood or sprinkler
irrigation.
Smart Controllers
Smart irrigation controllers use weather and soil moisture data to automatically
adjust watering schedules and amounts. These controllers, which can be retrofitted
to existing irrigation systems, help ensure that crops receive the precise amount of
water they need while avoiding excess watering. Studies show that smart controllers
can improve irrigation efficiency by up to 20% compared to traditional timers.
Recycled Wastewater
Treated wastewater from sewage treatment plants can be a valuable source for
agricultural irrigation. Recycling wastewater for irrigation helps farms cut their use of
freshwater supplies. The use of recycled wastewater, also known as graywater, for
irrigation is becoming more common, especially in drought-prone and water-scarce
regions. Proper treatment and monitoring are required to ensure water quality and
avoid potential health risks.
Implementing efficient irrigation systems and smart technologies are practical
solutions that can significantly curb water usage in agriculture. While these
innovations may require initial investments, they provide both environmental and
economic benefits through increased crop yields, reduced operational costs, and
preservation of freshwater resources. Widespread adoption of efficient irrigation
methods and recycled wastewater are critical steps towards sustainable water
management and food security.
Water Recycling and Reuse Technologies
The Water recycling and reuse technologies offer promising solutions to address
water scarcity and improve sustainability.
Water Treatment and Filtration
Advanced filtration systems can treat wastewater and make it suitable for reuse.
Microfiltration and ultrafiltration remove particles like sediments and bacteria.
Reverse osmosis uses semi-permeable membranes to remove ions and larger
molecules. Distillation involves boiling the water then condensing the resulting
steam. These methods produce very pure water for industrial use or potable water.
Greywater Systems
The Greywater refers to wastewater from showers, sinks, washing machines, and
other sources excluding toilets. Greywater systems collect, treat, and reuse this
water for non-potable purposes like irrigation, cooling systems, and toilet flushing.
They reduce the volume of wastewater entering sewers or septic systems by up to
50%. Simple systems filter and disinfect the water before reuse while more
advanced systems also include components like equalisation tanks, pumps, and
controls.
Rainwater Harvesting
Rainwater harvesting systems collect and store rainwater runoff from rooftops for
later use. The water is filtered and can supply non-potable water demands like
irrigation, laundry, and toilet flushing. These systems are easy to implement and
provide a sustainable source of water, especially in areas with seasonal rainfall. They
also help recharge groundwater levels and reduce flooding and erosion.
Water Reuse in Agriculture
Treated wastewater can be used for agricultural irrigation, especially in areas where
freshwater is scarce. Primary and secondary wastewater treatment can remove
pollutants to levels suitable for irrigation of certain crops. Tertiary treatment using
filtration and disinfection produces reclaimed water suitable for irrigating most crops.
Using wastewater for irrigation also provides nutrients to crops and helps conserve
potable water. Strict guidelines regulate water quality and crop type to ensure public
health safety.
New technologies enabling improved water recycling, reuse and sustainability are
tackling the global water crisis through conservation and resource recovery.
Widespread adoption of these solutions can help ensure access to clean water for
future generations.
Smart Water Monitoring Systems
Smart water monitoring systems utilise Internet of Things (IoT) technologies to track
water usage and detect leaks in real time. These innovative solutions help reduce
water waste and lower utility bills.
Smart Metres
Smart water metres monitor usage remotely and provide real-time data on water
consumption. Utilities can track water usage to determine peak demand periods and
identify excess use, while consumers gain insight into their water usage patterns and
can make adjustments to reduce waste. Some smart metre systems can even detect
leaks by monitoring flow rates and usage over time.
Leak Detection Systems
Leak detection systems use wireless sensors to monitor water flow in pipes. The
sensors detect changes in flow rate, pressure, sound, or temperature to identify
potential leaks. These systems can pinpoint the location of a leak within a few feet,
allowing for quick repair. Some municipalities have reported reducing water loss by
over 50% after implementing smart metering and leak detection systems.
Automated Shutoff Valves
Automated shutoff valves, also known as smart valves, can detect leaks and
automatically shut off the water supply to minimise water waste and property
damage. The valves remain open during normal use but close immediately if a leak
is detected. Smart valves provide 24-hour protection and conservation for both
residential and commercial plumbing systems.
Implementing smart water solutions like monitoring systems, leak detection, and
automated shutoff valves can significantly reduce water waste by enabling active
management and immediate response. These innovative technologies are leading
the charge against the global water crisis one drip at a time. Together with water
conservation best practices, smart water systems have the potential to transform
how we use and protect this vital resource.
Conclusion
You have seen that significant progress is being made in developing innovative
solutions to address the global water crisis. From breakthroughs in desalination and
water filtration technologies to advances in water conservation and reuse,
researchers around the world are leading the charge. While the challenges ahead
remain enormous, by supporting organizations at the forefront of developing
scalable and sustainable water solutions, and by making changes in our daily lives to
reduce water usage, each of us can play a role in ensuring access to clean water for
all. The future is bright if we make it a priority to adopt and invest in the
technologies and policies that will make the difference in this fight. Together, we
have the power and responsibility to solve the world’s water crisis.

water purification technology developed by Panasonic. Credit: Panasonic Corporation.

Water treatment using photocatalysis has

gained prominence in recent years due to its
efficiency in treating contaminated water. The
technology utilises photocatalyst and
ultraviolet (UV) rays to remove toxic
substances from water.
Panasonic developed a technology that binds
the photocatalyst (titanium dioxide) to a
commercial adsorbent and a catalyst called
zeolite, ensuring effective separation and
recovery of photocatalysts from the water for
reuse. Titanium dioxide can mineralise a
range of organic compounds into safe end
products. The catalyst uses UV radiation
either from sunlight or artificial light to
separate substances.
Photocatalysis can break down a range of
organic materials, estrogens, pesticides, dyes,
crude oil, and microbes such as viruses and
chlorine-resistant pathogens, as well as
inorganic compounds such as nitrous oxides.

The new water technologies that could save the planet
This article is more than 10 years old

What are the new and emerging technologies that will help
business overcome the scarcity of clean, fresh water?
Will Henley

The well was a transformative invention, though it is often

overlooked. This source of freshwater, vital for the expansion of
inland communities, dates back nearly 10,000 years – 3,000
years before the wheel was ever imagined.

The well is but one of a long list of innovations in water

technology that have enabled human development to continue
apace. Sophisticated pipeline networks and treatment plants
today furnish us with this elixir of life and industry. As intense
pressure is placed on the planet's limited water supplies,
businesses are again turning to technological innovation. New
and emerging inventions should see human civilisation through
the 21st century and, with any luck, the next 10,000 years.

Nanotechnology in filtration: According to the World Health

Organisation, 1.6 million people die each year from diarrhoeal
diseases attributable to lack of safe drinking water as well as
basic sanitation. Researchers in India have come up with a
solution to this perennial problem with a water purification
system using nanotechnology.
The technology removes microbes, bacteria and other matter
from water using composite nanoparticles, which emit silver ions
that destroy contaminants. "Our work can start saving lives,"
says Prof Thalappil Pradeep of the Indian Institute of Technology
Madras. "For just $2.50 a year you can deliver microbially safe
water for a family."

It is a sign that low-cost water purification may finally be round

the corner – and be commercially scaleable.

Technology, Madras Photograph: Indian Institute of Technology/Thalappil

Membrane chemistry: Membranes, through which water

passes to be filtered and purified, are integral to modern water
treatment processing. The pores of membranes used in
ultrafiltration can be just 10 or 20 nanometres across – 3,000
times finer than a human hair.
But while membrane chemistry has been around for several
years, it remains a source of intense research and development.
"Chemistry significantly contributes to innovative water
treatment solutions, such as turning salt water into fresh water
suitable for human consumption," says Yannick Fovet, head of
global development for water at chemical company BASF.
Recent breakthroughs have been credited with forcing down the
cost of desalinated water from $1 per cubic metre to
between $0.80 and $0.50 over five years. New ceramic
membranes are helping to make treatment more affordable.
"Membrane technology is increasingly important because system
integrity, longevity and costs have improved," explains Paul
Street, business development director for engineering firm Black
& Veatch.
Seawater desalination: Although holding much promise for the
future, seawater desalination is still extremely expensive, with
reverse osmosis technology consuming a vast amount of energy:
around 4 kilowatt hours of energy for every cubic metre of water.

One solution being explored in Singapore, which opened its first

seawater desalination plant in 2005, is biomimicry - mimicking
the biological processes by which mangrove plants and
euryhaline fish (fish that can live in fresh briny or salt water)
extract seawater using minimal energy. Another new approach is
to use biomimetic membranes enhanced with aquaporin: proteins
embedded in cell membranes that selectively shuttle water in
and out of cells while blocking out salts.

Harry Seah, chief technology officer for PUB, Singapore's

national water agency, says: "If science can find a way of
effectively mimicking these biological processes, innovative
engineering solutions can potentially be derived for seawater
desalination. Seawater desalination can then be transformed
beyond our wildest imagination."
Smart monitoring: In developing countries alone, it is
estimated that 45m cubic metres are lost every day in
distribution networks. Leaks are not only costly for companies,
but increase pressure on stretched water resources and raise the
likelihood of pollutants infiltrating supplies.
"It does not make commercial sense to invest billions in
additional reservoirs and water catchment, treatment plants
[and] pumping stations, when as much as 60% of water produced
is unaccounted for," says Dale Hartley, director of business
development at SebaKMT, a water leak detection specialist.

New monitoring technologies help companies to ensure the

integrity of their vast water supply networks. Electronic
instruments, such as pressure and acoustic sensors, connected
wirelessly in real time to centralised and cloud-based monitoring
systems will allow companies to detect and pinpoint leaks much
quicker.

Intelligent irrigation: Approximately 70% of the world's

freshwater is used by the agricultural industry. Applying a more
intelligent approach to water management by
deploying precision irrigation systems and computer algorithms
and modelling is already beginning to bring benefits to farmers
in developed countries.

However, while this approach embraces new instrumentation

and analytical technologies, innovation comes from a change in
mindset that emphasises the importance of measuring and
forecasting.

"In the old days there was not so much stress on measuring
because we thought we had plenty of water," says Carey Hidaka,
smarter water management expert at IBM. "It's a bit of a
paradigm switch for the water industry, which like others is used
to throwing new engineering developments at problems."

Wastewater processing: Engineering still has its place,

however. Many people living in urban areas, even in advanced
economies, still do not have their sewage adequately treated and
wastewater is often discharged, untreated, into rivers and
estuaries or used as irrigation water.

New technologies are promising to transform wastewater into a

resource for energy generation and a source of drinking water.
Modular hybrid activated sludge digesters, for instance, are now
removing nutrients to be used as fertilisers and are, in turn,
driving down the energy required for treatment by up to half.

"There is an urgent need for wastewater systems that are more

compact, so that new plants can be built in urban areas where
land is scarce and for upgrading and expanding extant facilities,"
says Dr David Lloyd Owen, an advisor to the board of Bluewater
Bio, a specialist in wastewater treatment.

green more efficient way to deal with sewage. Photograph: Bluewater Bio

Mobile recycling facilities: An unexpected by product from the

explosion of the global hydraulic fracturing industry has been
demand for highly mobile water treatment facilities. Investment
is being channelled into reverse osmosis units that will allow
companies to treat high volumes of water to extract gas and
injected into the subsurface.

"There will be knock-on benefits as products [will be developed]

with new applications where the price tolerance is much lower,"
says Peter Adriaens, professor of environmental engineering and
entrepreneurship at the University of Michigan.

Adriaens adds: "As these technologies develop and learn to treat

high volumes of water, we will see cheaper, more potable
treatment systems and we will start to move away from massive
centralised treatment systems."
