1. polyacrylamide, also known as flocculant. It seems to be a white small particles or powdered solids, and this agent has a better effect, so it is a commonly used sludge dehydrating agent. Polyacrylamide is a high molecular weight polymer, and it is also divided into anionic, cationic, non-ionic and other types, so when choosing, you need to do several tests to determine the model.

2. polyaluminum chloride, also known as water purification agent. The appearance is yellow particles or powder. It is more common in coal washing plants or sand washing fields, and the sewage concentration is not high, and the belt filter press can be used to dehydrate the equipment.

3. 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.

4. others, such as ferric chloride, polyferric sulfate, aluminum sulfate, lime, polyferric aluminum chloride, etc., its main role is to flocculate and precipitate the sludge in the sewage, so as to enter the dehydration equipment to achieve the purpose of sludge dehydration.

In industrial production, the sludge dewatering agent selected by different industries, different dewatering equipment and different sewage concentration is not the same. Combined with the actual situation to choose the appropriate effect is better. Here we recommend the sludge dehydrating agent independently developed and produced by Works Chemical, which has a low water content after dehydration and a relatively good effect.
