| "Yu Quan" PAFC product as iron oxide in the PAC and 3, aluminum and iron salt coagulant hydrolysis and coagulation mechanism on the basis of in-depth study of the development comes, it sets aluminum and iron salt coagulation advantages, and the introduction of more dollars anion - sulfate ions, ion pairs of aluminum and iron ions are patterns there were significant improvements, the degree of polymerization also greatly improved. Appearance: Liquid product are transparent brown or red-brown body, no precipitation. Solid product SEPIA, reddish brown powder or granular. Easy dissolve in water, can be used for drinking water, industrial water and industrial wastewater, sewage treatment. Coagulation effect except for the remaining performance color reduce turbidity, there floc formation block, adsorption of high-performance, Sludge Dewatering filtration characteristics of a good performance, particularly in the treatment of high turbidity water, the low temperature and low turbidity water, the treatment effect than alum, polyaluminum chloride, PFS, three iron oxide good effect . The low temperature and low turbidity of the water purification particularly pronounced effect, may increase alkaline agents and other incomparable coagulant effect |
