Polyacrylamide and Polymeric Aluminium Chloride in the Mixed Use of Precautions

Polyacrylamide is a high molecular water-soluble polymer, is a highly efficient Flocculant for wastewater treatment, according to the ionic type can be divided into anionic polyacrylamide, cationic polyacrylamide and nonionic polyacrylamide, and amphoteric polyacrylamide.

Polymeric Aluminium Chloride is an inorganic polymer coagulant, referred to as polyaluminum PAC, due to the bridging effect of hydroxide ions and polymerization of multivalent anions and the production of higher molecular weight, higher charge of inorganic polymer Water Treatment Chemicals. In the form can be divided into two kinds of solid and liquid, solid according to the color is divided into brown, beige, golden yellow and white, different colors of polymeric aluminum chloride in the application and production technology also has a big difference.

Polymeric Aluminium Chloride itself is also a water purification agent, in some industries that do not require high water quality components of a single case, the treatment effect can also meet the discharge requirements. Polyacrylamide in the treatment of wastewater has a very superior effect, alone can achieve very satisfactory results, but it is not everything, in many cases and a little inorganic coagulants with better results. Polyacrylamide and Polymeric Aluminium Chloride must pay attention to the following points when used together:

1.Polyacrylamide and Polymeric Aluminium Chloride can not be dissolved in a dissolving tank.
2.Determine the model of polyacrylamide used with Polymeric Aluminium Chloride through experiments.
3.Determine the sequential order of polyacrylamide and Polymeric Aluminium Chloride through repeated tests.
4.Determine the dosage of polyacrylamide and Polymeric Aluminium Chloride through experiments.
5.Control the reaction time of waste water and two kinds of chemicals.
