Precautions for The Use of Polyacrylamide in Sludge Dehydration

Pay attention to the use of polyacrylamide in sludge dehydration. There are many types of polyacrylamide, so the selection of the type is more important, because it is an important factor affecting the effect, and then it is the problem of the operation process after the selection.

Operational Problems of Polyacrylamide Used in Sludge Dewatering
1. Water pressure problem, sometimes due to insufficient water supply pressure, the dissolution funnel of the material feeder cannot send the polyacrylamide agent into the preparation pool, resulting in blockage. The solution is to use a water pump to increase the water pressure.
2. The sludge dehydration polyacrylamide solution is recommended to be prepared and used immediately to prevent it from being left for too long and may affect the treatment effect.
3. When the container is cleaned, it should be cleaned in all aspects, so that the impurities sticking to the wall of the drum can be better cleaned up, and the drum can be given a balanced speed.
4. Regularly adjust the operating frequency of the dehydrator. When the dehydrator vibrates violently, it should be prohibited to feed again immediately, and the next step should be dredged first.
5. The concentration of sewage sludge is relatively high during water purification. At this time, it is best to let the sewage stand for a period of time, and then extract the clean solution above to increase the concentration of sludge for treatment.
