Reverse Osmosis (RO)

We design, manufacture and install RO Plant for drinking, commercial, industrial and laboratory research applications. Reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semipermeable, meaning it allows the passage of solvent but not of solute.

To illustrate, imagine a semi permeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

The membranes used for reverse osmosis systems have a dense polymer barrier layer in which separation takes place. Since Reverse Osmosis does not occur naturally, it must be created by applying pressure to the high solids water in order to force it through the membrane, with pressures from 8 - 14 bar for fresh and brackish water, and 40 - 70 bar for seawater, which has around

24 bar (350 psi) natural osmotic pressure which must be overcome.
Flow rates: 250 LPH to 50000 LPH or more
Installation: Skid or floor mounted or mobile
Operation: Fully / semi-automatic or manual
Pretreatment: Feed water compatible
Membrane: As required or best suitable
Vessel: SS / FRP

An efficient pretreatment is essential to enhance performance, membrane life and overall operating cost
As particulate matter presents in raw water, it becomes mandatory to pre-treat feed water in order to protect membranes from fouling or damaging; therefore, pre-treatment directly impacts the performance of reverse osmosis membranes. It is the quality of feed water, which decides which pre-treatment method is required; media filtration, UV filtration and Ultrafiltration are common reverse osmosis pretreatment solutions.
