500LPH Ro Filtration System One Stage Reverse Osmosis Water Purification Plant

Low pressure membrane:

Due to the advantages of saving energy consumption and reducing the pressure level of related mechanical parts, which leads to the decrease of material cost, the application proportion of ultra-low pressure membrane has been increasing since 1996, which is most prominent in the use of small devices mainly using 4 inch membrane. Take the largest domestic reverse osmosis membrane supplier, American Hedeneng Company, for example, 80% of the 4-inch film sold in the past two years is ultra-low pressure film. The application of ultra-low pressure film in large devices has also shown a significant upward trend. At present, the largest device using ultra-low pressure film in China has a water yield of 650 tons/hour.

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.

A positively charged reverse osmosis membrane

Now widely used low pressure, ultra-low pressure composite film material are aromatic polyamide, the membrane surface are negative charge, there are membrane manufacturers have developed a surface with positive charge low pressure composite film, this film is mainly used in the preparation of high resistivity high pure water system, in Japan, The positive charge film ES10C produced by Nitto Denko has achieved high pure water resistivity of 10 ~ 15 megohm in the three-stage reverse osmosis system in the semiconductor industry, and the final water resistivity of the three-stage reverse osmosis system produced by Hyundai Electronics in Korea is 8 ~ 9 megohm. A 170 t/h three-stage reverse osmosis system in a semiconductor factory in Shanghai also reached the above targets. In addition, the resistivity of water produced by reverse osmosis is 1 ~ 4 megohm in the two-stage reverse osmosis system of the scale of 5 ~ 20 tons/hour in some domestic pharmaceutical factories. In 2000, the domestic pharmaceutical industry will put into production 20 sets of such reverse osmosis systems.

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.
