Sludge dewatering needs to use sludge dewatering agents, then what are the sludge dewatering agents? Add what medicine effect is good? How and how much to add? About a series of problems of sludge dewatering agents, now Works Chemical Xiaobian will give you a brief talk:
Sludge dewatering, as the name implies, is to dehydrate the mud after sewage settlement, so that the sludge can be better disposed of.
There are many kinds of sludge dewatering agents, the traditional sludge dewatering agents mainly have polyaluminum chloride, polyaluminum ferric chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide.
Now Works Chemical Xiaobian to introduce a new sludge dewatering agent - sludge synergist; The sludge synergist developed and produced by Works Chemical is a characteristic polymer that acts as a drying agent in the sludge dewatering process. Compared with traditional PAM flocculants, it can significantly reduce the water content of sludge, and replace all or part of the inorganic flocculants and conditioners used in the sludge deep dewatering process, such as polyferric chloride, polyaluminum chloride, and lime. Achieve true sludge reduction, while maintaining sludge properties and organic matter content, without changing filtrate pH value and salt content.
The new sludge dewatering agent also has the following characteristics:
1. with the sludge, the formation of fine, strong small floc, greatly reduce the specific resistance of the sludge dehydration process.
2. it can achieve rapid and continuous dehydration of sludge, achieve solid-liquid separation, reduce the moisture content of sludge and the purpose of real reduction.
3.all or part of the replacement of inorganic flocculants will not increase the salt content of the filtrate and improve the operating conditions of the sewage treatment plant.
4. is conducive to reducing anaerobic reaction calcification and overflow site scaling.
5. can reduce the moisture content of the sludge to 40%-60%, the sludge weight reduction effect is good.
