1.1, reverse osmosis equipment technology

Reverse osmosis technology is the most advanced and most energy efficient membrane separation technology. The principle is that in the above solution under the action of osmotic pressure, on the basis of other substances not through the semipermeable membrane and these substances and water separation. As a result of reverse osmosis membrane in the membrane pore size is very small (only about 10A), so it can effectively remove the dissolved salts, colloid, microorganism, organic matter ( removal rate as high as 97%-98% ). Reverse osmosis is the high pure water equipment in one of the most widely used desalination technology, its separation of object is the ion in the solution and molecular weight of hundreds of organic matter; reverse osmosis ( RO ), ultrafiltration ( UF ), microporous membrane filter ( MF ) and electrodialysis ( EDI ) technology of membrane separation technology. Come nearly 30 years, reverse osmosis, electrodialysis, ultra filtration and membrane filtration has entered the industrial applications, mainly used in electronic, chemical, pharmaceutical, food and drinking water in areas such as.

1.2, reverse osmosis equipment, reverse osmosis equipment working principle

A. reverse osmosis equipment and osmotic pressure

Reverse osmosis equipment is common phenomenon in nature, such as a cucumber into the salt water, cucumber will become smaller due to water loss. Cucumber water molecules into the saline solution is the process of infiltration process. If one only water molecules through the film to a cistern partition into two parts, in the diaphragm are injected into the water and saline on both sides to the same height. Over a period of time can find water level lowering, and salt water level rise. We put the water molecules through the diaphragm to move into the brine is called osmosis phenomenon. Water level elevation is not endless, to a certain height will achieve a balance point. When the diaphragm ends of liquid level difference represents the pressure is called the osmotic pressure. The osmotic pressure of the size and concentration of salt directly related.

B. reverse osmosis phenomenon and reverse osmosis water purification technology

In the above apparatus achieves a balance, if in salt end surface under certain pressure, at this time, the water molecules will end to end by saline water migration. Under the pressure of the liquid molecules in dilute solution by solution to the strong migration process the phenomenon is known as reverse osmosis phenomenon. If the salt added to the above facilities at one end, and in the end imposed over the saline osmotic pressure, we can be received at the other end of pure water. This is the reverse osmosis water principle.

The production of pure water reverse osmosis equipment key has two, one is a selective membrane, we call the semipermeable membrane, two is a certain pressure. Simply put, the reverse osmosis membrane has many holes, these holes size and water molecules are of considerable size, due to bacteria, viruses, most organic pollutants and hydrated ions are much larger than water molecules, thus not through the reverse osmosis membrane and reverse osmosis membrane separation of the aqueous phase through. Numerous kinds of impurities in water, soluble salts are the most difficult to remove. Therefore, often based on desalting rate to determine the reverse osmosis water purification effect. Reverse osmosis desalting rate depends mainly on the reverse osmosis membrane selectivity. At present, high selectivity of the reverse osmosis membrane desalination rate can be as high as 99.7% ( conductivity is ≤ 10 μ s.cm ).

In 1.3, the reverse osmosis process equipment:

Raw water ( tap water), booster pump, more medium filter ( Ishi Eisa (2-4 /4-6) /SS / manganese sand filter, activated carbon filter ) ( coconut shell carbon / carbon shell / coal carbon )→softener ( optional ), a reverse osmosis host, two stage reverse osmosis host, reverse osmosis cleaning device and the ultraviolet sterilizer, precision filter, water points ( conductivity is ≤ 5 μ s.cm ).
