2m3/H Reverse Osmosis System for Water Purification

Reverse osmosis principle

RO (Reverse Osmosis) is a practical technology, that is, to enable certain components of the solution to selectively pass through the unit under the external pressure, achieving desalination, purification or concentration and separation. Used in water treatment projects, it can remove the majority of ion in water as well as the fine particles, bacteria and organic compounds in water. Now, it is a state-of-the-art and economical approach in water treatment equipment. In the reverse osmosis process. The water of the high salt content is pressurized and delivered continuously by the high-pressure pump to the RO unit and the RO unit containing reverse osmosis membrane elements and pressure vessels divides the outflow into the penetrating fluid of low salt content and concentrated solution of high salt content. The proportion of penetrating fluid and concentrated solution of water supply is controlled by a regulating valve.

With the static pressure on both sides of the membrane as the driving force, the RO unit allows only a solvent (usually referred to as water) to pass through the membrane separation device while intercepting ionic substances. The removal rate for various ions in water is shown in Table 2— 18— 1.




Field of application of reverse osmosis (RO)
Brackish water desalination: Drinking water of fluoride areas;
Hardness removal of high hard water: Pure water used by power plants, electronics, pharmacy, metal processing;
Water used for food, beverages and canned pure water: Special water for hospitals and laboratories.
