Product description:
reverse osmosis process uses semi permeable spiral wound membranes to separate and remove dissolved solids, organic, pyrogens, sub micron colloidal matter and bacteria from water. Water permeates the minute pores of the membrane and is delivered as purified water. Impurities in the water are concentrated in the reject stream and flushed to drain. Reverse osmosis is capable of removing 97-99% of total dissolved solids (TDS), 99% of organic, including pyrogens, and 99% of all bacteria in the feed water.
Technological process
raw water+ raw water tank+ raw water pump+ sand filter+ carbon filter+softener (optional)+ security filter+ high pressure pump+ reverse osmosis system+ pure water tank+ UV sterilizer (ozone generator) +precision filter + water supply points
Working principle
Reverse osmosis,short for RO, which is under external pressure, and some components in solution
through selective, so as to realize the purpose of desalination, purification and enrichment
separation. When it is used in water treatment equipment, it can remove most ions in water, and
also the fine particles, bacteria and organic impurities. Nowadays, it is the advanced and economic
water treatment equipment over the world. Reverse osmosis is used of high pressure pump
continuously to force the water content high salt delivered to the RO device, RO device comprises
a reverse osmosis membrane element and the pressure vessel, input water is divided into low salt
of penetration solution and high salt of concentrated solution. Water is controlled by regulating
valve according to proportion of the concentrated solution and penetration solution.
Application:
Electronic industry--water for washing electronics components like integration electric circuit, silicon
wafer, and display tube
Water for Pharmacy industry
Water for chemical industry
Boiler feed water for electric industry
Water for food industry--drinking pure water, beverage, beer, wine, health products, etc
Sea water and brackish water desalination
Drinking pure water--houses, communities, companies, etc.
Other process water
Water for electroplate industry
