Reverse osmosis equipment for water purification

Reverse osmosis equipment is currently one of the world's water treatment equipment in the production of pure water advanced equipment, its operating costs are low, economic, easy to operate, reliable operation. The production capacity of the equipment is the value under raw water 25℃ and standard production conditions. Changes in water temperature and production conditions will affect the production capacity of the equipment.

Single-stage reverse osmosis process features:

●Applicable to areas with low salt content in raw water

●Lower total carbon (organic matter) in the produced water

●Simple structure

Characteristics of two-stage reverse osmosis process:

●Suitable for areas with high salt content in raw water

●Good conductivity of produced water

●Lower one-time investment

●Lower operating costs

●Good stability

Reverse osmosis membrane main performance:

●Comprehensive desalination rate of >97~99%.

●Effective removal of organic matter retained molecular weight >150MW

●Bacteria removal rate >99

●Thermogen removal rate >99

●Silica removal rate >98.5%

Removal rate of heavy metal ions >96~99

Pure water and solutions containing solutes separated by a semi-permeable membrane that can only pass through water, at this time, the pure water side of the water spontaneously through the semi-permeable membrane, into the solution side, the solution side of the water surface rises, this phenomenon is osmosis. When the liquid level rises to a certain height, the pressure on both sides of the membrane to reach equilibrium, the solution side of the liquid level is no longer elevated, at this time, there is a pressure difference between the two sides of the membrane, known as osmotic pressure. If the solution side with a pressure greater than the osmotic pressure, the water molecules in the solution will be squeezed to the pure water side, this process is exactly the opposite of osmosis, we call it reverse osmosis (reverse osmosis). We can see from the process of reverse osmosis that due to the pressure, the water molecules in the solution go into the pure water and the amount of pure water increases while the solution itself is concentrated.
