Municipal wastewater is the wastewater produced by residents in their daily lives, such as toilet water after flushing, wastewater after cooking and washing dishes, bath water, etc. It mainly comes from residential buildings and public buildings, such as houses, institutions, schools, hospitals, stores, public places and toilets of industrial enterprises.   Polyacrylamide is also generally divided into water treatment and sludge treatment in the municipal wastewater industry. Earlier it was more often used in the latter part of sludge dewatering in domestic wastewater treatment plants, using cationic polyacrylamide, generally used in centrifuges, belt filter presses, plate and frame filter presses. With the tightening of national environmental protection policy, most areas of the country have to carry out the first-class A standard transformation, some municipal wastewater after biochemical treatment of water quality can not meet the standard discharge will need to increase the depth of treatment process, and then through a high-efficiency sedimentation tank to deal with.This process is mainly to add inorganic flocculants (polymeric aluminum chloride, aluminum sulfate, etc.) and anionic polyacrylamide together with flocculation and precipitation to reduce the index of harmful substances in the sewage, so that the sewage meets the discharge standards.   As for how to...

Detailed description of polymeric ferric sulphate for power plants: Polyferric sulphate for power plants can be adapted to different sewage water conditions. Various wastewaters, organic, inorganic, sewage, and complex sewage treatments in wastewater systems with variable pH changes. The technical advantages and economic advantages solve the shortcomings of large consumption and dehydration of industrial wastewater and small domestic sewage treatment plants, which reduces the large demand and operating cost of the enterprise, electroplating wastewater treatment, electroplating wastewater treatment and reuse of flocculant It is the most cost-effective, most potential, and highly applicable sewage treatment flocculant.
