sodium ferrate is Hexavalent iron salt , with strong oxidizing, soluble in water can release a large number of atomic oxygen, to kill the bacteria and viruses in water effectively. At the same time itself is reduced to a new eco Fe (OH) 3, this is a kind of high quality inorganic flocculant, can remove suspended substance in water effectively. Experiments show that, because of its strong oxidation and flocculation effect, the disinfection and decontamination effect of ferrate is better than Chlorine disinfectant and permanganate. more important, it does not produce any harmful substances to human body in the whole water disinfection and purification process. Ferrate is recognized as green disinfectant by scientists.

Except for the excellent oxidative bleaching, efficient flocculation, and excellent bactericidal effect, the ferrate also can remove the Odor substances in the sludge quickly and effectively. Ferrate deodorant is to oxidize odor substance such as H2S, CH3SH, (CH3)3S, NH3 ect. converte them to the safe and odorless substance. Due to ferrate has a very strong oxidizing in the entire range of PH value, it is the ideal method for deodorizing treatment sludge.

Recently, our technical staff developed a new process for producing ferrate aiming at the demands of the market, this craft is simple and safe, raw material is easily obtained and cost low. Use effect is excellent, especially to the tertiary sewage treatment, able to drop COD of the polluted water below 20, has a promising perspective.
