First of all, we must know the principle. When the sludge dewatering machine works, it is generally the physical and chemical reaction of the sludge pressure filtration process. The physical process mainly depends on the extrusion and draining function of sludge dewatering, and the chemical reaction is through the coagulant. And other chemical components to synthesize fine particles of sludge water into larger volume particles to facilitate extrusion and drainage. The most important component is flocing agent, commonly known as pam, which chemically aggregates small particles in sludge into macromolecular flocs. Precipitation filtration process.
Here we should note that the flocculant needs to be used together with the dewatering machine to exert its maximum effect. The direct application in the sewage is basically not very good. Therefore, in order to provide the efficiency of the mud dewatering machine, it is necessary to put a flocculant during use.
Of course, flocculants are also classified into many types, including inorganic flocculants and organic flocculants. Among them, inorganic flocculants can be classified into iron and aluminum according to metal salts, as well as modified cations, cationic organics, and various acryl type cations. Etc. Different types of flocculants have different effects on different properties of sludge water, so different flocculants should be placed according to the nature of the sludge water to achieve better results.
