Sludge filter press is mainly used for sludge dewatering treatment in major industries. In the process of sludge weight reduction and resource recycling, the lower the water content, the lower the cost savings. However, most plate and frame filter presses are used for sludge dewatering. The moisture content in the latter mud cake is still high. So how to solve this problem?
Works Chemical- Sludge conditioner, sludge dewatering synergist manufacturer
The answer is effective sludge chemical conditioning. The high moisture content of the sludge pressed by the plate and frame filter press is mainly because the sludge has not been effectively chemically adjusted and modified, and it is no longer deformed after being pressed to a certain extent. On the basis of effective conditioning, high pressure can speed up the dehydration rate and improve the dryness after pressing.
The sludge conditioned by sludge dehydrating agent is injected into the filter chamber of the filter press at a pressure of about 1.0MP, which is conducive to efficient filtration of free water in the sludge. The sludge accumulated in the filter chamber reaches the design capacity of the filter press and enters the filter press. High pressure crimping. The final dryness of the press dehydrated sludge is closely related to the effect of chemical conditioning modification, as well as the filling degree of the press chamber, the increase rate of press pressure and the retention time of press pressure. When the chemical conditioning achieves better results, the use of high pressure feeding and high pressure pressing can shorten the time of the entire press section and improve production efficiency. Automatic discharge and backblowing of filter material (filter cloth) are completed at the same time, which can reduce the labor intensity of the controller, and improve the efficiency of the completion of the action, and maintain the effect of the filter cloth to intercept sludge and permeable water.
