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 choose the right polyacrylamide in municipal wastewater treatment, it is necessary to choose according to the nature of sewage and sludge in the wastewater treatment plant, the treatment process and the sludge dewatering equipment selected. Generally, the beaker selection experiment is done first, and then the on-board pilot test is done. The more models you have, the more you can choose the right model.
Henan SECCO Environmental Protection Technology Co., Ltd. Founded in 2003, is located in Gongyi city Henan province, a nationial water purifier industry cluster mainly professional manufacture the production of polyacrylamide such as : anionic polyacrylamide, cationic polyacrylamide, non polyacrylamide and other polymer with a complete set of sewage flocculantion treatment solutions according to different usage scenarios.
