　　Reverse osmosis water treatment is a pressure difference to drive a membrane separation technology, with a separate high, no phase change, simple and efficient characteristics. Reverse osmosis membrane “pore” has little to nanometer (1nm = 10-9m), the scanning electron microscope can not see the surface of any “filter” hole. Higher than the osmotic pressure in the operation of raw water pressure, water molecules can be reverse osmosis through semi-permeable RO membrane, production of pure water, while a large number of inorganic ions in raw water, organic matter, colloids, microorganisms, such as being the original RO membrane heat retention.

　　Reverse osmosis water treatment equipment is usually raw water pretreatment system, reverse osmosis purification systems, ultra-purified processing system composed of three parts. The main purpose of preprocessing is to make raw water to reverse osmosis membrane separation component of the water required to ensure the stable operation of reverse osmosis purification system. Reverse osmosis membrane system is a one-time 98% of raw water to remove ions, organics, and 100% of micro-organisms (in theory) the most cost-effective means of purification. Ultra-purification treatment system integration technology through a variety of reverse osmosis pure water to further remove the remaining trace ions, organic matter and other impurities in order to meet water quality objectives for different uses of the final requirements.

　　Pretreatment of reverse osmosis water treatment equipment systems usually polypropylene fiber (PP) filters and activated carbon (AC) filter form. Higher on the hardness of raw water softening resins need to install filters. PP water filter can effectively remove the original machinery of more than 5μm particle impurities, and the large jelly rust pollutants, such as protection of the follow-up filter, which is characterized by large pollutant, low price. AC carbon filter can be efficiently adsorbed chlorine and some organic matter in raw water, colloid, the protection of polyamide reverse osmosis composite membrane from chlorine oxidation. Softening resin can be removed most of the raw water calcium and magnesium ions to prevent scale buildup in follow-up RO membrane surface, improve water recovery.

　　Water treatment membrane processes can be divided into (RO), ultra filtration (UF), micro filtration (MF), Nan filtration (NF), electro dialysis (ED) and the membrane contactor (MC), etc. In water treatment membrane process, membrane components are made from the form required for the separation of cell membrane separation device, commonly used in industry, plate membrane form, tube type, spiral type and hollow fiber type.

　　Compared with conventional separation techniques, Water treatment membrane processes have the following characteristics:

　　1) Water treatment membrane processes are separable or even hundreds of thousands of molecular weight of substances for the efficient separation process.

　　2) The basic water treatment membrane processes do not occur “with” changes, low energy consumption, energy conversion rate.

　　3) Water treatment membrane processes can be carried out at room temperature for heat-sensitive materials such as fruit juice, enzymes, drugs, separation, classification and enrichment.

　　4) Membrane water treatment equipment, fewer moving parts, simple structure, operation, control and easy maintenance.

　　5) Water treatment membrane separation efficiency, equipment, small size, covers an area of less wide application.

　　Water softeners used to remove water hardness of the water processor for a class.

　　When the water calcium and magnesium content is relatively high, the water hardness will be higher. Hardness of water in the heating process is easy to form dirt, scale formation of the external tube wrapped in heating, resulting in heat transfer is not smooth, making the low heating efficiency, but also cause serious heating pipe burst, causing accidents; high hardness when washing with water and detergent in, resulting in low efficiency detergent; hardness of the wash-off clothing will become solid yellow color gradually darkens.

　　The role of water softeners: water softeners treated by heating the water will not form the dirt, is conducive to the safe use of heaters; washing clothes, towels, beautiful color, soft; slippery moist skin after bathing. Therefore, high-quality water softeners are necessary to choose life.

　　Attention： not suitable for drinking softened water.
