I.  RO(pure water) equipment:

The working principle of RO is to permeate RO membrane by means of high pressure, the solvent of water spreads from high concentration to low concentration, and then reach the purposes of separation, purification, concentration. Due to its osmotic direction opposite to natural osmotic direction, it called reverse osmosis, which is mainly to separate the ion range, no need of heating, there is no phase-change; RO can remove the bacteria, viruses, colloids, organic substances and over 98% dissolved salts in the water. This method has many features of low run cost, simple operation, high automation, stable product quality etc.

II. Application scopes:

Commercial drinking water preparations: pure water, soda water, spring water etc.

Domestic drinking water preparations: living area, villages, official building, factories and mines enterprises, dual water supply engineering
Water for food beverage industry: fruit juice, wines, dairy, health care products, fruit and vegetable process etc.
Water for textile dyeing and printing industry: water for dyeing and printing, weaving machine etc.
Water for medical pharmacy industry: oral liquid of Chinese traditional medicine, large volume transfusion, medical treatment preparation etc.

Ultrapure water for electronic industry: electrolytic capacitor, crystal tube, picture tube, integrated circuit etc.

Water for chemical engineering: chemical dialysis, solvent reagents, biological product, daily cosmetics etc.

Sea water and brackish water desalinization: ocean ships, fresh water make up offshore drilling, desalinization treatment of salty water quality.

Boiler makeup circulating cooling: boiler softened water treatment, central air conditioner water, air conditioner circulating cooling water. Water for artificial culture: aquaculture, flower culture

III. Technology design:

1) Single-stage technology design:

2) Raw water tank→ raw water pump→ sand filter→ carbon adsorber→ water softener (or calculating drug feeding) → precision filter→ high pressure pump→ RO→ ozone generator→ pure water tank→ water-user
