Introduction Of The Use Of Polyacrylamide

Introduction Of The Use Of Polyacrylamide

We have already understood the functions and effects of water treatment agents in detail. There are many different classifications according to their functions and types. Polyacrylamide is one of the linear polymer polymers, and its molecular chain contains a certain number of radicals. It can absorb solid particles suspended in water, bridge ions or aggregate particles into large flocs through charge neutralization, accelerate the sedimentation of suspended particles, accelerate the clarification of the solution, and improve the filtering effect. The detailed usage of it will be introduced as below for you.

1. Use in sludge dewatering

When used for sludge dewatering, cationic polyacrylamide can be selected according to the sludge, which can effectively dewater the sludge before the sludge enters the filter press. When dewatering, it produces large flocs, does not stick to the filter cloth, and does not disperse during the filter press. The mud cake is thick and the dehydration efficiency is high.

2. Use in the treatment of organic waste water

When used in the treatment of domestic sewage and organic wastewater, such as food and alcohol wastewater, wastewater from urban sewage treatment plants, beer wastewater, MSG factory wastewater, sugar wastewater, feed wastewater, etc., The effect of cationic polyacrylamide is better than anionic, nonionic and inorganic salts for several times or tens of times higher, because this kind of waste water is generally with negative charge.

3. Purification of raw water from rivers and lakes

Polyacrylamide can be used for the treatment of tap water with river water as the source of water. Because of its low dosage, good effect and low cost, especially when used in conjunction with inorganic flocculants, so it will be used in water plants as flocculant from the Yangtze River, Yellow River and other basins.

The above is the detailed use of polyacrylamide. As a water treatment agent, it has more performance in sewage treatment. However, in addition to its important uses in the above three aspects, it can also be used as a reinforcing agent and other additives in paper making to increase the retention rate of fillers and pigments, and increase the strength of paper; as oilfield additives, such as clay anti-swelling It is a thickening agent for oilfield acidification; it can play a great role in textile sizing agent, stable sizing performance, less sizing, low breakage rate of fabric, and smooth cloth surface.
