Sludge dewatering is the dewatering of the mud after sewage settlement, so that the sludge can be better disposed of. There are many kinds of sludge dewatering agents, which are divided into traditional sludge dewatering agents and new sludge dewatering agents. According to different sludge needs to choose the corresponding sludge dewatering agents to get better results.

First、 the traditional sludge dewatering agents are: polyaluminum chloride, polyaluminum chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide, polyferric sulfate, etc.; The new sludge dewatering agents include sludge conditioner and so on.

1.polyacrylamide pam, also known as flocculant, also some industries called white medicine. 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.polyaluminum chloride pac, also known as water purifier, some industries call it xanax, because its appearance is yellow particles or share powder. For this agent as a sludge dewatering agent, the common industry is coal washing plants and sand washing sites, the sewage concentration is not high, the use of belt filter dewatering equipment can be a good sludge dewatering.

3. the dehydration effect of lime is very good, but the bad disadvantage is that it will corrode the equipment, so that the filter cloth hardens and needs to be replaced frequently.

4. Ferric chloride has chloride ions and is not friendly to environmental protection.

Second、 the new sludge dewatering agent:

Sludge deep dewatering agent is an organic sludge dewatering agent, which can not only reduce the dewatering rate, but also has the advantages of non-corrosion equipment and no chloride and calcium ions. It is an ideal sludge dewatering agent.
