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 not possible, which involves the use of sludge dewatering agents. What are the sludge dewatering agents? How to choose?

1. Polyacrylamide pam, also known as flocculant, is also called white medicine in some industries. Because its appearance is white small particles or powder, this agent has a good flocculation effect, so it is commonly used as a sludge dewatering agent.

2. Sludge conditioner, also known as sludge dehydrating agent, is a chemical agent that can change the surface structure of the sludge, reduce the solid surface load of the sludge, reduce the specific surface area of the sludge surface, and destroy the bacterial structure. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on. Combined with the plate and frame mud press, the sludge moisture content can be reduced from more than 90% to 40%-60%, and the sludge reduction can be fully realized.

Regarding the selection of sludge conditioner as a sludge dewatering agent, the sludge conditioner of Works Chemical is generally selected, the main reason is that Works Chemical sludge conditioner can reduce the moisture content of the sludge.

3. Others, such as ferric chloride, polyferric sulfate, aluminum sulfate, lime, polyferric aluminum chloride, etc., its main function is to flocculate and precipitate the sludge in the sewage, so as to enter the dehydration equipment to achieve the purpose of sludge dehydration. Its dewatering effect is not as good as that of sludge conditioner, and the amount is still large.

Different industries, different dewatering machinery and equipment, different sewage concentrations, the selection of sludge dewatering agents is not the same, here Works Chemical Xiaobi recommend you or sludge conditioner, because the sludge conditioner after dewatering the water content of the sludge is low, the effect is relatively better.
