Desalination Reverse Osmosis Systems

Keeping in mind the variegated demands of our clients, we are persistently engaged in manufacturing, supplying and exporting a qualitative range of Desalination Reverse Osmosis Systems. Featured with a semi permeable membrane, our RO systems are designed to remove different types of water molecules, solvents, impurities and ions. Widely used in domestics, industries and commercials; our RO systems are designed to provide drinkable pure water. The body of the systems are constructed from stainless steel by employing cutting-edge technology. Offered Desalination Reverse Osmosis Systems are high in demand among the clients for the following features:

• Rigid construction
• High performance
• Longer working life
• Hassle-free operations

Other details:

We are among the leading names involved in the fabrication and supply of the Desalination Reverse Osmosis Systems. We are highly appreciated by our clients for designing these systems. The three liquid streams involved in the process of desalination processes are as follows:

• Saline feed water

• Low-salinity product water

• Very saline concentrate

With the help of two output streams the saline water which is drawn from open sea/underground beach well sources are separated by desalination process:

• Low-salinity product water

• Very saline concentrate streams

Some of the special features are as follows:

• The product water of desalination process is generally water that has less than 500 mg/1 dissolved solids

• Suitable for most domestic, industrial as well as agricultural uses

Some of the technical description is as follows:

• In RO process, water from pressurized saline solution is separated from dissolved salts by making it flow through a water-permeable membrane

• The permeate (Liquid flowing through membrane) is encouraged to flow through membrane by pressure differential created between pressurized feed water as well as the product water (Which is at near-atmospheric pressure)

• The remaining feed water continues through pressurized side of reactor as brine

• Major energy requirement is for initial pressurization of feed water

• For brackish water desalination, operating pressures range from 250 to 400 psi

• For seawater desalination is from 800 to 1000 PSI

The four major components/processes of our reverse osmosis systems consist of the following:

• Pre-treatment

• Pressure boosting

• Membrane separation

• Post-treatment stabilization

Pre-treatment:

The incoming feed water is pre-treated to make it compatible with membranes by adjusting the pH, removing suspended solids as well as adding threshold inhibitor to control scaling caused by constituents like calcium sulphate.

Pressure Boosting:

• The pump raises pressure of pre-treated feed water to operating pressure appropriate for membrane as well as salinity of feed water

• We also use Energy Recovery Devices that are used in tandem with Pressure Boosters so as to cut down the energy costs

Separation:

• The permeable membrane stops passage of dissolved salts while permitting desalinated product water to pass through

• Applying feed water to membrane assembly also results in freshwater product stream as well as concentrated brine reject stream

• As no membrane is perfect in its rejection of dissolved salts, small percentage of salt passes through membrane & remains in product water

• Reverse osmosis membranes also come in a variety of configurations (Most common being Thin Film Composite)

Post Treatment:

The product water from membrane assembly usually requires pH adjustment & degasification before being transferred to distribution system for use as drinking water. The disinfection is also done if water is being used for drinking purposes.
