Talking about the misunderstanding of type selection of polyacrylamide

The choice of polyacrylamide is very important. A good choice can not only treat sewage better, but also reduce the amount and save production costs. Do you know what misunderstandings you should be aware of when choosing?

1. Misunderstandings about the selection of polyacrylamide:

The larger the molecular weight of polyacrylamide, the better the flocculation power and the better the effect. So the higher the molecular weight, the better the effect?

Not necessarily, there are 100 types of polyacrylamide, and the types of sewage produced by different enterprises are different. Some are acidic water, some are alkaline water. Some are neutral water quality, some have oil, some have a lot of organic matter, some have color, and some have a lot of sediment. There are a variety of situations, and not one polyacrylamide can solve all problems. All types of effluents can be treated with qualifications and need to be selected through small experiments. In the machine test, the optimal dosage is determined to achieve the effect of small dosage and low cost.

Secondly, molecular weight and ionicity are two important indicators of polyacrylamide, so does polyacrylamide depend on the choice of different ionicity in the industry?

Ionicity refers to the negative and positive of ionic charge and its charge density. The higher the ionicity, the lower the molecular weight. The higher the ionicity, the higher the product price.

Ionicity affects the density and water content of the product flocculant, and further experiments are required to confirm the type of polyacrylamide required.
