RO reverse osmosis system
The pure water and the containing solute solution with only one kind of separated by a semipermeable membrane water, at this time, pure water side spontaneously through the semipermeable membrane to the solution side, side solution of water surface elevations, this phenomenon is permeation. When the liquid level rises to a certain height, the pressure on both sides of the membrane to reach a balance, the liquid level of the solution side is no longer raised, then, there is a pressure difference on both sides of the film, known as the osmotic pressure. If the solution side plus a greater than osmotic pressure, the water molecules in the solution will be squeezed to the pure water side, this process is exactly the opposite of penetration, called reverse osmosis. We can see from the reverse osmosis process, due to the role of pressure, the solution of water molecules into the pure water, pure water increased, and the solution itself is concentrated.
The equipment used in reverse osmosis membrane is a semi permeable spiral wound membrane, when raw water with certain pressure is sent to the reverse osmosis membrane, water through the membrane of the small aperture, after collection are obtained in pure water, and water impurities such as soluble solid, organic matter, colloid substances and bacteria is reverse osmosis membrane interception, interception liquid concentration and was removed. The first level reverse osmosis can remove more than 97% of the dissolved solids in raw water, the two stage equipment can remove more than 99% of the dissolved solids, more than 99% of the organic matter and colloid, almost 100% of the bacteria. Two stage RO equipment is the use of the first level of water into the second level as the raw water use, can make the production of pure water to achieve a higher quality, applicable to the pharmaceutical, electronic industry, such as the need for high water production.
RO equipment is the world's water treatment equipment in the production of pure water, one of the most advanced equipment, low operating costs, economic, convenient operation, reliable operation, the user is the first choice for the production of pure water equipment.
