Reverse osmosis water pretreatment system Pretreatment system
Reverse osmosis water pretreatment system, the pharmaceutical industry RO pre-treatment system quartz sand - activated carbon - softening tank, this product mainly application with reverse osmosis, ultrafiltration pretreatment system, applications mainly in biomedical engineering water treatment, chemical food water treatment works, drinking water treatment works some of the requirements of high degree of automation, and quality of water treatment projects more rigid

Product Process: quartz sand - activated carbon - softening resin tank

Flow: (1) quartz sand filters, shallow media filter I mainly use high-quality washed quartz sand filler, the control part adopts Tuzu automatic control head, Fleck automatic control head or run New series of automatic control of domestic first-class well-known brand. is the use of quartz sand as a filtration medium, at a certain pressure, the higher the turbidity of the water through granular quartz sand grains or a certain thickness of the filter, effectively retain remove suspended solids, organic matter, colloid particles, microorganisms, chlorine, odor and some heavy metal ions, and ultimately to reduce water turbidity, water purification effect of an efficient filtration equipment commonly used quartz sand filter, activated carbon, anthracite, manganese sand, etc. widely used to agricultural irrigation, chemical, petroleum, metallurgy, mining and other industries.

(2) activated carbon filters, activated carbon filters of our company mainly made of high quality carbon or coconut husk charcoal filler to ensure that users of the results, the control part Tuzu automatic control head, Fleck automatic control head or domestically-run new series of automatic . first-class well-known brand of activated carbon adsorption principle is: the surface layer of an equilibrium concentration in the surface of the particle, then the impurities adsorbed organic substances into the activated carbon particles, high adsorption initial use, but over time, the adsorption capacity of activated carbon. will be reduced to varying degrees, also decreased absorption effect. If the water turbidity, high organic content in water, activated carbon filter will soon lose function. Therefore, the activated carbon should be regularly cleaned or replaced.

(3) of demineralized water filter, softened water filter selection famous Purolite, Rohm and Haas or domestic glory resins and other famous brands, the control part Tuzu automatic control head, Fleck automatic control head or domestically-run new series of automatic first-class works of well-known brands: the principle of ion exchange, removal of calcium and magnesium ions scaling when containing hardness ions in raw water through the exchanger resin layer inside, water calcium and magnesium ions will be adsorbed sodium ions with the resin displacement occurs, the resin adsorption of calcium and magnesium ions and sodium ions into the water, so that the switch from the inside out of the water is to remove the softened water hardness.

Due to the hardness of water is mainly formed by calcium, magnesium, and said that it is generally used cation exchanger (water softener), the water Ca2 +, Mg2 + (the formation of scale main ingredient) to displace, with the inner resin Ca2 +, Mg2 + increases, resin to remove Ca2 +, Mg2 + decreased performance.

When the resin to absorb a certain amount of calcium and magnesium ions, it must be the regeneration process is the salt in the salt water rinse tank resin layer, the hardness of the resin ion exchange out in, with the regeneration waste water discharge tank, the resin He resumed soften exchange.

Softening, by definition that is reduce water hardness. Demineralized water system consists of three parts, namely part, salt regeneration section and the control section ion exchange ion exchange technology is softening system works, its subject is an ion exchange resin, due to the hardness of the water The main form and said that it is generally used cation exchange resin, the water Ca2 +, Mg2 + (the formation of scale main ingredient) to displace, with the inner resin Ca2 +, Mg2 + increases, the resin to remove Ca2 +, Mg2 + performance gradually from calcium, magnesium decreases. Therefore, when water softening equipment used for some time, to be part of the regeneration salt resin regeneration treatment, recovery efficiency of the resin, to improve the life of the resin. The control section of the entire system can be achieved automatically, based on system uptime or by salt water to automatically regenerate.
