Can polyferric sulfate and bleaching powder be added at the same time

Can polyferric sulfate(PFS) and bleaching powder be added at the same time? The two agents have different uses in sewage treatment. Polymeric ferric sulfate focuses on coagulation, turbidity removal and phosphorus removal, and plays the role of coagulation and accumulation of pollutants, while bleaching powder and bleaching water mainly eliminate poison and sterilize. When both coagulation and sterilization are required in water treatment, polymeric ferric sulfate is usually used for coagulation treatment first, and then disinfectant is added for sterilization. It is not used together. Why?

After adding polyferric sulfate for flocculation and sedimentation, the sewage shall be accumulated from beginning to end, and then add bleaching powder for disinfection and sterilization. At this time, if bleaching powder is added quickly, polyferric sulfate will be used to oxidize and disintegrate the sludge particles after flocculation and accumulation, which will affect the flocculation effect, resulting in high effluent turbidity and rising cod. How to prevent polymerized sulfuric acid

polyferric sulfate is mainly used to coagulate from beginning to end to make the dirty water clear, dissolve in water, adsorb and settle the small particles in water, produce alum deposits, and then separate alum from water. Get the effect of removing turbidity.

In normal use, there will be no dispute between polyferric sulfate and bleaching powder. Bleaching powder is calculated and added according to the content of microorganisms in water. When adding bleaching powder, it is best to detect the water quality first. Hypochlorite dissolved in bleaching powder and water can kill microorganisms and bacteria in water and play the role of disinfection and sterilization.

When using polyferric sulfate and bleaching powder for sewage treatment, attention should be paid to adding polyferric sulfate to flocculate and clear the water, so that the alum settled by polyferric sulfate and suspended solids can be removed, and then adding bleaching powder for disinfection. Polyferric sulfate solution should be stirred with water to better remove turbidity and other pollutants.
