产品名称：2stageReverseOsmosissystem

Product description:

With the report of raw water and the different requirements in different field, we can make a appropriate design for you.

1) Adopts imported RO membrane from America, which can remove 99.7% inorganic salt,

heavy metal ion and completely get rid of colloid, microbiology organic materials, germ, protozoa, pathogens, bacteria, inorganic chemical and so on.

2) No need to add any chemicals, stable pure water quality, and no pollution drained, low produce cost.

3) Equipped with pretreatment system, such as active carbon absorption filter and PP sediment filter.

4) 304 stainless steel rack and pipe accessories connection.

5) Equipped with auto pressure protection system and on -line monitor.

6) Automatically and manually wash RO membrane. Also the design of washing the RO membrane is by chemical solution (citric acid or sodium hydroxide optional

7) The lifespan of the whole system is long, operation simple, the applicability is strong.

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:

1. Electronic industry: Pre-filter for ultra pure water, chemical products and pure water

2. Food and beverage industry: filter for mineral water, wines and fruit juice

3. Medicine industry: filter for drug liquid, gases

4. Chemical industry: filter for organic solvent

5. Petroleum industry: filter for oil-field flooding
