REVERSE OSMOSIS SYSTEM

 

PROCESS DESCRIPTION

 

 

Raw water gets collected in raw water tank; the raw water feed pump feeds it to the Multi Grade Filter. The Multi Grade Filter will remove all suspended solid up to 50 micron particle size.  The filtered water is then feed to the RO system through a cartridge filter.

 

 

The 5 micron cartridge filter removes all suspended solids greater than 5-micron size.  Antiscalant will be injected in the feed water at the beginning of cartridge filter to prevent precipitation of calcium carbonate salt on the membrane and prevent it from fouling. Also Acid will be injected in feed water before cartridge filter to maintain feed water pH in range 6-7.  At this pH, solubility of scale forming salts is increased there by minimizing membrane fouling.

 

 

The raw water will now be feed into the R. O module after pressurizing it through a high pressure pump. The R.O. module consists of semipermeable membranes. When the pressurized water is fed to the R.O. membrane, the membrane rejects salt ions and only water is allowed to pass through the membrane.  The salt ions are continuously washed out of the module (reject/concentrate stream) and the permeate stream is the desalinated product water stream.  Some amount of the concentrate stream is recycled to the RO module inlet to minimize wastage / increase water recovery.  The permeate stream contains free carbon dioxide and is feed to a degasser column.

 

 

In the degasser column water flows in the downward direction through the bed and Raschig rings.  Air is introduced from the bottom of the degasser and it passes through the bed and raschig rings in the upward direction. The raschig ring bed ensures intimate contact between air and water. The carbon dioxide in water escapes from the top of the degasser along with air. The water from degasser tower is collected in degasser sump tank. The degasified water will be pumped in product water storage tank through degasified permeate transfer pump.
