REVERSE OSMOSIS PLANTS

SEAWATER DESALINATION

B&P Water Technologies manufactures a comprehensive range of

skid mounted or containerized reverse osmosis desalination plants
able to produce fresh water for potable or technical purposes.
The seawater containerized desalination reverse osmosis systems
are built inside metal shipping containers.
On request, offshore containers can be provided, certified according
to the strict rules foreseen by EN12079-1 and DNV 2.7-1.
The units supplied inside offshore containers can be installed on
offshore platforms and accommodation barges.
Special installations for hazardous areas can be provided.
Both the skid mounted and containerized seawater desalination
units are assembled and fully tested at our facility before being
delivered with no need for on-site system assembly, pipe work,
electrical wiring or mounting of components.

Containerized desalination unit – External view

In case of seawater containerized desalination units, the container also works as

shipping container so there is no need for wood crating or rental of sea containers to
transport the system to its destination. Our containers are designed for indoor or
outdoor permanent or mobile installations.
The complete sea water reverse osmosis system includes filtration, pumping
equipment, membranes, electrical controls, and chemical feed and control components.

As energy consumption is a big

issue in managing a desalination
plant, all our reverse osmosis
plants can be equipped with the
latest energy recovery systems.
Our seawater reverse osmosis
desalination plants are designed to
produce drinking water (salt Containerized desalination unit – Internal view
content less than 500 ppm) from
seawater with salinity up to 55000
ppm.
The end user shall
only connect
seawater feeding
Skid mounted desalination units pipes, product water
outlet pipe and brine
discharge pipe.
The plant is fully automatic to ease the operation of the end user.

All the
materials are
selected to
guarantee the
longest lifetime Skid mounted desalination unit
of the package
and to minimize
the routine maintenance; as an example, the seawater pipes under high
pressure are manufactured in UNS31803 Duplex stainless steel, while those
under low pressure are made in a-toxic PVC.
Plant operation and supervision is managed by a local control panel equipped
with PLC and operator touchscreen HMI.
Skid mounted desalination unit
We can provide systems to operate correctly with any power supply voltage (690V-460V-440V-
240V-230V) and frequency (50Hz-60Hz).

Local panels can be self-standing or panel mounted depending on the size of the unit and on
customer’s choice. Variable frequency drivers for the reverse osmosis high pressure pumps
can be panel mounted or self-standing depending on size and installation.

Remote plant supervision can be offered through the

web. Main plants parameters such as flowrates,
pressures and water quality can be remoted on a
web page. B&P Water Technologies will be able to
monitor the plant operation accessing the web page Local control panel
to verify that the system is running properly and, in
case of any malfunction or abnormal parameter, can determine the problem and suggest the
solution.

Each plant is equipped with CPI (Clean In

Place) system for periodical membrane
Main operating parameters cleaning, with all the chemical dosing
systems required to adjust seawater and
product water quality.

Injection of disinfecting agent (such as Sodium Hypochlorite) and chlorine excess

removal are usually no longer necessary since disinfection is achieved by means of
UV-C sterilizers manufactured in material suitable for sea water application
(Polyethylene or Duplex SS).

Sea water filtration is two steps wise; sand

filtration followed by micrometric filtration
guarantee absence of solid particles leading to
membranes lifetime shortening.

Our flexibility allows us to “customize” our products to fit

any particular need from our clients in terms of
accessories, components and quality of produced
water.

In case of open sea water intake we design and

fabricate customized filtering elements based on
“wedge wire” technology that can be connected to
intake concrete structures or can be connected to feed
pumps customized by B&P Water Technologies with
steel sleeve suitable for horizontal and vertical

VACUUM SEWAGE SYSTEMS

B&P Water Technologies developed its own technology for the vacuum suction and
transfer of waste waters. Compared with the traditional gravity systems, these units
offer the following advantages:

 Construction cost saving (small trenches)

 Small pipes diameters
 Booster pumps stations no longer required
 No sediments and clogging in the pipeline
 No leakages and smells, as the line is kept under vacuum
 Low energy consumption
Central vacuum station for sewage water The system is composed by: collection pits with valve, vacuum pipeline and central
vacuum station.

B&P Water Technologies is able to make the engineering and the supply for the complete system (pipeline and vacuum pits design up
to the vacuum station).
Our company has supplied its vacuum systems to the major marinas in Italy and abroad, for the suction of bilge and black waters.

WASTEWATER TREATMENTS
ACTIVATED SLUDGE BIOLOGICAL TREATMENT PLANTS
The treatment process involves the biological oxidation of the raw water with
air and sludge recycle. The effluent is oxidized by means of an extended air
injection in order to obtain the total oxidation of the biological components.
The sedimentation chamber separates the sludge from the clarified water,
which is collected to a chlorination chamber.
This plant represents the best solution for single users or small communities.
The compact construction permits the installation in parallel of two or more
units, allowing to treat a huge volume of raw water.
The tank is completely made painted carbon steel. The submerged type
aeration system guarantees a long plant lifetime.

CONTAINERIZED MEMBRANE BIOREACTORS
A NEW CONCEPT TO TREAT CIVIL WASTEWATER.
B&P Water Technologies manufactures a comprehensive range of “containerized” biological wastewater treatment plants based on MBR
technology.
When used with domestic wastewater, MBR processes produce effluent of high quality enough to be discharged to coastal, surface or
brackish waterways or to be reclaimed for urban irrigation.
It is possible to operate MBR process at higher mixed liquor suspended solids (MLSS) concentrations compared to conventional
settlement separation systems, thus reducing the reactor volume to achieve the same loading rate, and the physical barrier imposed by
the membrane system provides complete disinfection of the treated effluent.
Our containerized
MBR systems are
built inside of metal
shipping containers
and are assembled
and fully tested at
our facility before
being delivered with
no need for on-site
system assembly,
pipe work, electrical
wiring or mounting
of components.
The container also
works as the
shipping container
so there is no need
for wood crating or
rental of sea
containers for
transportation to
final destination.

OIL/SOLIDS REMOVAL UNITS
CORRUGATED PLATE INTERCEPTION SEPARATION

CPI Packages are commonly used to separate oil and fats with low specific gravity. The water flows through corrugated plates
manufactured in polypropylene, Oil and fats particles adhere to the plates and, due to low density, move upwards. An adjustable
skimming device collects the oil/fats from water surface. Any eventual sludge is collected in a separate section for extraction and
disposal. When the wastewater contains both low density and high density
oils/fats, an Air Flotation Package (DAF) must follow the CPI package.

DISSOLVED AIR FLOTATION PACKAGES (DAF )

Flotation Packages are commonly used to separate oil and fats having specific gravity close to
water. In such a case, the separation occurs only by air flotation. The air bubbles adhere to the
oil/fats particles to reduce the density and thus allows the lifting of the particles. A skimming
device collects the supernatant while the clarified water is extracted from a dedicate section.
Flotation packages include air saturation skid and may be proposed as circular type or
rectangular type depending on size. Rectangular type may be equipped with double scraping
chain to collect any eventual suspended solid in the water precipitating by gravity.
The units are
supplied with full
instrumentation,
equipment and
control panel.
