What is the reason why polyacrylamide cannot achieve the expected effect when used
Some customers have found that the effect is not very good after using polyacrylamide.
The quality of the polyacrylamide is inconsistent with the quality promised by the polyacrylamide manufacturer during the selection of the experiment at that time. It is not necessarily that the quality is not good, or the manufacturer has sent you a defective product. The effect of poor factors, there are the following points.
The reasons for the poor effect of polyacrylamide and several methods to solve the problem of polyacrylamide are as follows:
Reason one: the water source concentration is not stable.
For example, when you add medicine to treat sewage, the quality of the sewage is very poor, and the sewage concentration is not very stable, which will lead to some uncertain factors affecting the effect of polyacrylamide.
Reason two: wrong selection (and wrong model selection)
The specific analysis of the problem, polyacrylamide models are divided into anionic, cationic, non-ionic, zwitterionic four types of polyacrylamide, different types of polyacrylamide types, selection and use methods are also different. For example: When using flocculation, cationic polyacrylamide is suitable for highly toxic, organic-containing sewage flocculation treatment and organic sludge dewatering process. Anionic polyacrylamide is suitable for flocculation treatment of sewage with large suspended particles, high turbidity and positive charge. Non-ionic polyacrylamide has strong flocculation effect in acidic water quality because it does not have the activity of amide group on ion side chain. function group. Therefore, the key to solve this problem is to find a suitable polyacrylamide according to the actual industrial project.
Reason three: experimental water deterioration
It may be that the sewage samples sent by your company to amide manufacturers have undergone qualitative changes after many days of journey, resulting in certain differences between amide selection and original sewage use. Solution: If it is such a problem, we can provide on-site service and do a selection test on site to solve the customer's sewage problem.
