At present, the industrial economy continues to develop, accompanied by more and more problems, including the disposal of sewage, sludge, people are also more and more concerned. Dewatering of sludge is the method used by many industries at present, so can the sludge be dehydrated directly by using dewatering machinery and equipment? This is obviously impossible, the use of mechanical dewatering equipment can only discharge a small amount of water in the sludge, a large amount of water can not be pressed out through the machinery. So what method can improve the dehydration rate of dehydration equipment? Now Works Chemical Xiaobian will solve the problem of incomplete mechanical dehydration for everyone!

Many sewage treatment plants will use belt filter press, plate and frame filter press to deal with the problem of sludge dehydration. However, the effect of the treated sludge is not ideal, and the moisture content of the sludge is still as high as more than 80%. Now Works Chemical Xiaobian take the plate and frame filter press as an example. In order to solve the problem that the sludge dewatering of the plate and frame filter press is not complete, the more effective way is to use the sludge dewatering agent together with the plate and frame filter press. At present, there are many water treatment agents on the market, such as polyacrylamide, polyaluminum chloride, ferric chloride and so on. However, these traditional water treatment agents can reduce the moisture content of the sludge slightly. Today, Works Chemical Xiaobian will teach you how to correctly choose the use of sludge dehydrant to help you reduce the moisture content of sludge.

After the use of sludge dehydrating agent (sludge conditioner), the sludge moisture content is reduced significantly, and the sludge moisture content can be reduced to 35%-55%, and the mud pressing efficiency of plate and frame filter press and other dewatering equipment can be effectively improved by 100%-500%, which shorens the mud pressing cycle. Compared with polyacrylamide and other dehydrating agents, this agent does not need to add lime and does not contain chloride ions. More conducive to sludge incineration, brick making, composting and so on.
