The use of polyacrylamide is focused on the initial sedimentation tank stage. General use of polyaluminum chloride + anionic polyacrylamide use, so that impurities in the water can be physically precipitated, so that the water is clear.

Most of the sewage produced by starch manufacturers need to go through the corresponding sewage treatment before discharge, commonly used agents are polyacrylamide, polyaluminum chloride and so on.

The main pollution of slaughterhouse wastewater is the high content of organic matter, the wastewater is reddish brown, there is a strong odor and the pollution concentration changes, in the treatment of uncertainty and process requirements are relatively high.

In general, we often use cationic polyacrylamide and polyaluminum chloride to treat aquaculture wastewater, so that not only the effect is better but also save the cost of sewage treatment agents.

In all sewage, pharmaceutical factory sewage is relatively more difficult to treat than other sewage, pharmaceutical factory sewage organic matter is more, the water quality is messy. Poor biodegradability and other characteristics. How do pharmaceutical companies use polyacrylamide to treat sewage?

 Coke is an essential raw material for the steel industry. With the rapid development of the steel industry, the demand for coke is increasing, and the amount of coking wastewater is also increasing. The pollutants contained in coking wastewater include phenols, polycyclic aromatic compounds and heterocyclic compounds containing nitrogen, oxygen and sulfur, etc., which is a typical toxic and refractory organic wastewater. Polyacrylamide is a kind of linear polymer, with “all industry additives” said, it plays an important role in the treatment of coking wastewater. Polyacrylamide because it has a variety of active groups, and many substances affinity, adsorption form hydrogen bonds. Mainly flocculated negatively charged colloid, with turbidity removal, decolorization, adsorption, adhesion and other functions. It plays an important role in the treatment of coking wastewater.

The main sources of papermaking wastewater are waste water in the material preparation section, the cooking section, the pulping section, the bleaching wastewater and the waste water produced in the waste paper recycling process.

Urban sewage mainly comes from domestic wastewater, kitchen wastewater and toilet flushing water.General urban sewage treatment uses cationic polyacrylamide

With the rapid development of plastic factory, plastic factory industrial wastewater will follow. It is different from waste plastic products, can be directly recycled. Waste water from plastics plants needs to be rigorously treated before it can be discharged or recycled. Unsolved immediate discharge will cause great harm to the surrounding environment.

Ceramic wastewater mainly comes from process wastewater and equipment cleaning wastewater，ceramic wastewater discharge is large, suspended matter content is high, more harmful substances，polyacrylamide can separate suspended matter from water in ceramic wastewater.
