Polymerization iron sulfate--Waste water processing necessary


Pollution and shortage of water resources has become one of the serious problems facing a real human. Sewage treatment is imminent, the main sewage treatment technology with physical method, chemical method and biological treatment method. With the increase of pollution sources, water pollution is serious complex, often require a variety of processing methods combined to remove different types of pollution to a depth of purification.

Treatment of wastewater, coagulation is one of the indispensable method, coagulation is the waste water in the colloid in the flocculant is added under contact, collision, destabilization, flocculation integrated a certain particle size of aggregate, the final settlement by the action of gravity, has reached the purpose of solid-liquid separation. Coagulation mainly has two kinds of inorganic and organic. At present sewage treatment is mainly used coagulants are polyacrylamide (PAM), polymerization aluminum chloride (PAC), ferrous sulfate, polymeric ferric sulfate, ferric chloride, poly aluminum ferric chloride (PAFC) etc..

Polymeric ferric sulfate (PFS) is a new, high-quality, efficient, effective salts of inorganic polymer flocculants, flocculation performance, fast sedimentation rate, water purification effect is good, no two pollution, free from aluminium, chlorine and other heavy metal ions and other harmful substances, water without iron ion transfer, non-toxic harmless. In the turbidity removal, decolorization, deoiling, dewatering, sterilization, deodorization, algae removal, removal of COD, BOD and heavy metal ions, efficacy significantly; especially for the micro pollution, including algae, effect of low temperature and low turbidity raw water purification treatment significantly, the high turbidity raw water purification effect; the Lord to adapt to a wide range of pH value for 4-11, the optimum pH range 6-9, small water pH and total alkalinity changes after purification of processing equipment, little corrosion; dosage of small, low cost, processing cost can save 20%-50%. In wastewater treatment, because of the heterogeneous nature of the raw water, should act according to the different situation, commissioning or beaker test, to obtain the best conditions and the best dosage to achieve the best treatment effect.
