Polyacrylamide is a commonly used agent in wastewater treatment. It can play a very good purification role in all kinds of sewage. Acidic sewage is often produced in beverage, food, canned, desulfurization and other industries. Then we need to use polyacrylamide flocculant for these acidic sewage. In the face of acidic sewage treatment, how should we choose? The answer is: nonionic polyacrylamide.

The solid content of nonionic polyacrylamide is: 89%, the degree of hydrolysis is 5%, and the molecular weight is between 8 million and 12 million. Nonionic polyacrylamide is a very active polymer flocculant in the water purification industry. It can quickly add the activity of molecular weight amide groups, allowing it to obtain more water purification properties through polymerization. Compared with anionic polyacrylamide, non-ionic polyacrylamide has many characteristics: this flocculant has almost no effect on the pH range of sewage. Under medium-sized sewage or alkaline conditions, the flocculation effect is very average, but in acidic sewage, it can quickly settle and flocculate, which is much stronger than other flocculants.

Nonionic polyacrylamide

Methods of treating acidic wastewater with polyacrylamide:

1. It is necessary to first adjust the ph range to neutral for sewage. Then select a more suitable polyacrylamide and add it to achieve the effect of purifying sewage. When adjusting the pH range, you need to add alkaline substances first, such as sodium hydroxide, lime and other substances to turn acidic sewage into neutral sewage. Then select the appropriate polyacrylamide for addition, and cationic polyacrylamide is more commonly used.

2. Add non-ionic polyacrylamide directly without adding any alkaline additives. This kind of flocculant is very practical when facing acidic sewage and has good flocculation and sedimentation effect.

The above are the common methods of using polyacrylamide in the face of acidic sewage. I believe most of you will choose the latter, so choose non-ionic polyacrylamide, which can achieve a good water purification effect in sewage without adding any additional water purification. cost.
