There are many kinds of cationic polyacrylamide, the choice of cationic polyacrylamide is a difficult problem for customers. The ionic degree of cationic polyacrylamide is divided into more than 20-60 models. Today, Xiaobian explains the difference between 20 ion degree and 60 ion degree in sewage treatment.

What is cationic ionicity? The ionic degree is essentially the charge density, the number of charged ions, and the ionic degree determines how dense the floc is. Which product to choose depends on the nature of the water to be treated and the equipment used. The higher the ionic degree, the larger and tighter the action of impurity floc in sewage. Cations are mainly for urban sewage and negatively charged sewage. One thousandth of the cation into the water, can produce impurities in sewage, in the precipitation to play a bridging role. This is what we call sewage desulsification. After it is put into operation, we can see that the impurities in the sewage will precipitate quickly, separating the water from the impurities and facilitating the later operation of the desudging equipment.

Sludge dewatering how to choose cationic sludge dewatering how much ionic polyacrylamide? When we screen the cationic degree, we should first look at the size of the floc, too small flocs will affect the drainage speed, too large flocs will limit more water, thus reducing the biscuit degree. Sludge dewatering can adjust the floc size by selecting the ionic degree of polypropylene. Two, the strength of the flocculant, flocculant should remain stable, under shear will not break. Increasing the molecular weight of the cationic polyacrylamide or choosing the appropriate molecular structure is helpful to improve the stability of the floc.
