Cationic Polyacrylamide Emulsion, made by dispersion or the inverse Emulsion polymerization process, is a form of Polyacrylamide fluid. It has the property of solid polar flocculant that can absorb suspended solid particles in water through the groups in the molecular chain, so that large flocculant can be formed by bridging between particles or electroneutralization. It is divided into cationic polyacrylamide emulsion and anionic polyacrylamide emulsion.
Besides the advantages of solid polyacrylamide flocculant, polyacrylamide emulsion also has the advantages of high charge density, fast dissolution rate, low energy consumption, convenient storage and use. Compared with traditional cationic polyacrylamide products, polyacrylamide emulsion has a wider PH range, higher charge stability, better flocculation effect, less dosage and other advantages. It is also applicable to the construction site without large dissolving device.
Urban sewage treatment is also called municipal or domestic sewage treatment. China is a country with a very short water supply, so the protection of water resources is very strong, which includes the treatment and recycling of waste water. Polyacrylamide dry powder and its emulsion products are important water purifiers in water treatment. Cationic polyacrylamide emulsion for urban sewage treatment is mainly related to the solid content, molecular weight and ionic degree of the product. It is generally recommended to use cationic polyacrylamide emulsion with high ionic degree for wastewater treatment.
Cationic polyacrylamide emulsion is mainly used for solid-liquid separation process in secondary processing, used as a flocculant of sludge dewatering, generally speaking, the use of the high degree of ion product will have good effect. But different city sewage also can have very big differences, because the city sewage contains a large number of industrial wastewater and more different regional and industrial concentration, water quality is not the same, in the use of polyacrylamide used as flocculant best selection according to the specific application situation.
