500LPH Water Purifying System Two Stage Reverse Osmosis Pure Water Equipment
 
Pretreatment:
The pretreatment system of reverse osmosis water treatment equipment usually consists of polypropylene fiber (PP) filter and activated carbon (AC) filter. For raw water with higher hardness, it is necessary to install softening resin filter. The PP filter element can effectively remove the mechanical particle impurities, rust and large glue and other pollutants above 5μm in the raw water, and protect the subsequent filter, which is characterized by a large amount of pollution, low price. AC activated carbon filter element can efficiently adsorb residual chlorine and part of organic matter in raw water, colloids, protect polyamide reverse osmosis composite membrane from residual chlorine oxidation. Softening resin can remove most calcium and magnesium ions in raw water, prevent subsequent scaling and blockage on the surface of RO film, and improve the recovery rate of water.

Low pollution of membrane:
 
Membrane fouling is the greatest harm in reverse osmosis application, which not only shortens membrane service life and increases operation cost, but also directly affects the efficient and continuous operation of membrane system. At present, several low-pollution films with strong anti-pollution performance, long service life, low cleaning frequency and easy cleaning have come out. Heidergy LFC1 film has the characteristics of electroneutral surface and good hydrophilicity. It has become the leader of the low-pollution family and the only low-pollution film used in large-scale reverse osmosis devices in China. At present, it has been successfully run in several large power plants, automobile factories, electronic materials factories and tea concentration plants in China. In addition, DOW's anti-fouling film uses mirror technology, which also has good anti-fouling performance.
 
General reverse osmosis tap water or groundwater after the first level of reverse osmosis water treatment equipment treatment, water conductivity <10μS/cm, after the second level of reverse osmosis water treatment equipment water conductivity <5μS/cm or even lower, in the reverse osmosis water treatment equipment system assisted by ion exchange equipment or EDI equipment can prepare ultra-pure water, To achieve a resistivity of 18 megohm (conductivity =1/ resistivity) is reverse osmosis is to use enough pressure to make the solvent in the solution (usually referred to as water) through the reverse osmosis membrane (a semi-permeable membrane) and separated from the osmosis direction, can be used greater than the osmotic pressure of the reverse osmosis method for separation, purification and concentration of the solution. The main separation object of reverse osmosis membrane is the ion range in solution.
 
Process flow of RO Water Treatment System
Raw water → Raw water tank → Raw water pump → Multi-media filter (quartz sand filter) → Activated carbon filter → Soft water processor → Precision filter → High pressure pump → Primary reverse osmosis (RO) device → Purified water tank → High pressure pump → Two Stage reverse osmosis → ultraviolet sterilization device → water point.
