Introduction
• Access to clean and safe drinking water is a
fundamental human right, yet over 2 billion people
globally face water scarcity, leading to severe health
crises.
• Our project aims to develop a portable solar-powered
water purification system to provide a sustainable
solution in areas with limited resources.
• This system integrates solar energy with advanced
water purification technologies to ensure clean water
access in remote and emergency situations.
10/1/25 FYP Presentation 3
Objectives
• To develop a filtration system which is Solar-powered.
• Uses RO technology for remote places.
• Ability to remove contaminants from water sources
efficiently.
• Cost-efficiency and environmental benefit.
• To guarantee if the system is portable for emergency
use.
• To teach the local communities how to run and
maintain the system.

Background
• Contaminated water is a leading cause of diseases
such as cholera, typhoid, and hepatitis, especially in
underdeveloped regions.
• Reverse Osmosis (RO) technology is widely recognized
for its ability to remove up to 99% of contaminants,
including bacteria, viruses, and heavy metals.
• Using solar energy to power purification systems
addresses both energy and water challenges, making
it ideal for off-grid applications.

Filters Properties
Sediment filter Removes large particles like
sand, silt, and rust.
Activated carbon filter Adsorbs chlorine, pesticides,
volatile organic compounds
(VOCs), and improves taste and
odour.
RO membrane Removes up to 99% of dissolved
salts, heavy metals, bacteria,
viruses (Norovirus, Rotavirus),
and parasites.
UV filter Kills bacteria (Salmonella, E.
coli), viruses (Norovirus), and
parasites (Giardia).
Polishing filter Enhances taste and removes
remaining impurities.
