SEA WATER DESALINATION PLANTS

Rashi Aqua manufactures a comprehensive range of skid mounted or containerized reverse osmosis desalination plants.

The seawater containerised desalination reverse osmosis systems are built inside of metal shipping containers.

Both the skid mounted and containerised seawater desalination units 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.

In case of seawater containerised desalination units, the container also serves as the shipping container so there is no need for wood crating or rental of sea containers in which to transport the system to its destination. 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 content less than 500 ppm) from a seawater feeding with salinity up to 55000 ppm and capacity up to 500 m3/day.

The end user shall only connect seawater feeding header, product water outlet header and brine outlet.

The plant is fully automatic to ease the operation of the end user. All the materials are selected to guarantee the longest lifetime of the package and to minimize the routine maintenance; as an example, the seawater pipes under high pressure are manufactured in Duplex stainless steel, while those under low pressure are made in atoxicPVC.

Each reverse osmosis plant is equipped with CIP (Clean In Place) system for periodical membrane cleaning, with dosing systems for acid and antiscalet injection in sea water stream and neutralizing agent (NaOH or other) in permeate.

Injection of disinfecting agent (such as Sodium Hypochlorite) and chlorine excess removal are no more necessary since disinfection is achieved by means of UV sterilizer manufactured in material suitable for sea water application (Polypropylene 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 standard products to fit any particular request from our clients in terms of accessories, components and quality of produced water.

BRACKISH WATER RO UNITS

RashiAqua brackish reverse osmosis packages are designed to treat well waters and ground waters having a maximum salinity of 10000 ppm up to 500m3/day of product water and to satisfy any specific requirement of the end user/customer regarding the required quality of produced water. All our brackish water desalination units are skid mounted or can be assembled inside shipping containers.

Thanks to high flexibility and modularity of our brackish water desalination reverse osmosis packages, it is possible to remove undesired components from water, reduce the water salinity to achieve industrial water grade (for boiler or cooling tower application, as example), make the water potable or make it suitable for irrigation, Hatchery purposes.

Each brackish reverse osmosis desalination plant is fabricated with high compact design and easy to operate with first priority on client’s specific requirement. The high automation level of each plant allows to minimize the end user’s operation during the normal service time, while the selection of materials and components is done to maximize the plant lifetime.
