Printing and dyeing wastewater treatment agents - conventional chemical treatment agents Polyacrylamide (PAM) and Poly Aluminum Chloride (PAC) are flocculants and coagulants commonly used in sewage treatment. Both of them are generally used together to achieve the effect of coagulation, flocculation and sedimentation. It is mostly used to deal with floating matter, impurities, pigments and …
Polyacrylamide agents should be widely used and have good flocculation effect. However, high-quality products will also be affected by other factors during application, resulting in poor results. When using polyacrylamide for coal washing wastewater treatment, the following issues need to be paid attention to. When polyacrylamide is used in coal washing wastewater, attention should be …

Polyaluminum chloride is a new type of inorganic polymer coagulant. It is the most widely used variety with mature industrial production technology. It has become the mainstream product in the polyaluminum flocculant market. The earliest production and application was Japan. In the late 1960s, it was officially put into industrial production and application. Our country …
The drilling wastewater is mainly treated by chemical coagulation. The agents used are sodium hydroxide, polyaluminum salts, polyiron compounds and polyacrylamide.
Meat processing wastewater belongs to high suspended organic wastewater which is easy to biodegrade, and the variation range of wastewater quality and quantity is large. At present, the treatment of this kind of wastewater is mainly based on biological treatment technology, including aerobic, anaerobic, aerobic and other treatment systems. However, no matter what biological treatment …

Flocculant: It is a kind of thing that can reduce or eliminate the precipitation stability and polymerization stability of dispersed particles in water, so that dispersing particles condense and flocculating into aggregates. According to the chemical composition, flocculants can be divided into inorganic flocculants, organic flocculants and microbial flocculants three categories. Inorganic flocculants include aluminum …
