Dalian SEAHAN RE8040-BERO Reverse Osmosis Membrane

　　Dalian SEAHAN RE8040-BERO reverse osmosis membrane

　　Reverse osmosis membrane system is the typical membrane separation operation unit, which has been widely used in life drinking water purification, manufacturing process of producing pure water of electronics, chemical engineering, the electricity, textile, metallurgy and so on, which plays an important role in water treatment field.

　　Comprehensive characters of SAEHAN CSM reverse osmosis membrane:

　　1. The removal rate of inorganic substances is higher than that of organic substances;

　　2. The removal rate of ion solvend is better than that of nonionic;

　　3. High valent ion solvend removal is higher than low valent solvend. For example, Al3+ ion removal rate is higher than Mg2+, Na+;

　　4. Inorganic solvend removal rate is related with ion size and hydrated ion size. The bigger the ion radius or hydrated ion is, the higher the removal rate is.

　　5. The bigger the molecular weight of nonionic solvend is, the higher the removal rate is;

　　6. the gas molecules whose molecular weight is less than 100 can permeate membrane easily. For instance, ammonia, carbon dioxide, oxygen and hydrogen sulfide can permeate membrane easily;

　　7. The removal rate of weak acid is low, and which is related with molecular weight. The removal rate of three following acids will reduce with the decrease of molecular weight. The citric acid is higher than tartaric acid and acetic acid.

　　CSM reverse osmosis membrane characteristics:

　　1. High water flux and desalinization rate;

　　2. Good chemical stability; (PH2-12);

　　3. Long service life;

　　4. Anti-biological pollution;

　　5. Wide pressure range (20 - 1000psi);

　　6. Wide temperature range (4℃ - 45℃);

　　7. Good economy.
