Pretreatment equipment systems
Pure water, high pure water equipment are usually handled by pretreatment, desalination and precision of three parts. The main purpose of the pretreatment is to remove all or part of the suspended solids in raw water, microorganisms, colloids, dissolved gases and some organic matter, creating conditions for desalination and post-treatment processes required to achieve water reverse osmosis unit. At present, pretreatment equipment are: ① multi-media filters, ① activated carbon adsorption filter, ③ softening ion exchange, ④ precision filter.
Multi-media filter is mainly used to remove suspended impurities in water, the body with a central tube, under water distributor. Automatic valve operation, if the water quality is relatively poor, every 2-3 days to run automatic washing once. Can improve water quality, longer working cycle. Under normal circumstances the life of quartz sand 36 to 48 months.
Activated carbon adsorber is mainly free chlorine in water adsorption force of more than 99% of the organic matter and color also have a higher removal rate. Body with a central tube , the upper and lower water distributor , general and multi- media filter combination. Automatic valve operation, running seven days per backwash once. Generally the service life of the activated carbon is from 8 to 18 months.
Ion exchange softening less hardness for the adsorption of the raw water, the raw water by ion exchange of sodium in exchange, magnesium, calcium, a cation exchanger and the water contains sodium ion exchange, raw water is softened and a free or calcium and magnesium salts in water ( soft water ), automatic valve operation, the ion exchange resin regeneration cycle should be based on the raw water ( recommended every run once a week ) to decide, renewable automatically every time takes 60 minutes. Under normal circumstances the life of the resin is 24 to 36 months.
EDI (Electrodeionization) water treatment technology is a revolutionary, It cleverly electrodialysis and ion exchange technology integration, without acid, and continuous preparation High quality water. It has advanced technology, simple operation, good environmental characteristics, represents a Kinds of industries. Its appearance is a revolutionary advancement in water treatment technology, water marks Industrial final round into the ranks of the green industry.
EDI device consists of a booster pump, electro-deionization (EDI) Membrane block, DC power supply, flow meters, instruments and other components. Qualified RO product water pressurized by the booster pump Into the EDI system, EDI mixed ion exchange resin membrane stack will continue to remove the overcast raw water, Cations, and through the module so that the current will produce hydrogen and hydroxide ions in the vicinity of the water molecules female mold Ions, ionized hydrogen ions and hydroxide ions to the mixed ion exchange resin regeneration, the simultaneous exchange To the anion and cation through counter-proliferation by the yin and yang membrane into the membrane concentrated water discharge chamber, respectively. Electrical regeneration over Process so that the system does not require downtime EDI does not require the traditional recycling equipment can achieve sustained production of high-By weight of deionized water.
