PAC relatively good point. The following reasons: 1. Most domestic water companies are using PAC, such as low Beijing, Tianjin, Shanghai, Harbin, Zhengzhou and other cost of their use, processing small pipe corrosion, post-maintenance and low cost . 2. The water remaining aluminum ion is very small, in the normal life of the body does not pose a potential hazard. If there is damage, then, sewage treatment PFS, so there are so many aluminum utensils in the kitchen, it would not be a human life? 3. PFS by sulfuric acid as the reaction medium, the production of PFS, trivalent iron and aluminum oxide as the main factor in the treated water, Liupanshui PFS, its use is more suitable for low temperature, low turbidity waters . Such waters do not have the broad, generally concentrated in the north and northeast regions of local provinces. The PAC can make up for this deficiency. PFS summary, from low molecular weight to a polymer, from inorganic to organic and micro-organisms, from single type to the complex is the development trend of PFS. The pursuit of efficient, cheap, environmental protection is the goal of PFS developed, targeted to the development of non-toxic or low toxicity and efficient PFS to drinking water and other human activities related to water treatment toxicity and residues of not again causing secondary pollution, is an important direction for future research and development of PFS. Second, to strengthen the quantitative study of flocculation, lower production costs is imperative to develop new PFS. In dual drive theory and practice, the safe, non-toxic, efficient microbial PFS PFS of superseding traditional. Inorganic and organic polymer composite PFS also due to a combination of organic and inorganic advantage at home and abroad have been widely carried out, has become a hot research PFS.
