There are many kinds of sludge dehydrating agents, common are polyaluminum chloride, polyaluminum ferric chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide. So what kind of agents are added to the sludge dewatering, and the sludge dewatering effect is good? The dewatering effect of common sludge dehydrators on the market is not very ideal. The use of these more traditional sludge dehydrators can remove part of the water in the sludge, but it is still unable to achieve deep sludge dehydration.

At the same time, there are still some drawbacks in the use of traditional water treatment agents such as polyaluminum chloride, lime and ferric chloride. First, dewatering the sludge using these traditional water treatment chemicals requires a lot of energy. Second, lime will cause corrosion and seriously corrode dewatering equipment. Third, high operating costs. Fourth, the sludge dehydration is not complete, and the sludge after conditioning is easy to stain the filter cloth. Of course, the disadvantages of traditional dehydrants are far more than these. This is just a simple example of the four disadvantages of traditional dehydrators.

So what kind of sludge dewatering agent can effectively reduce the moisture content of the sludge, dehydrate the sludge deeply, and save operating costs? Sludge conditioner is a good choice, sludge conditioner is also known as sludge dehydrating agent, is a can change the sludge surface structure, reduce the sludge solid surface load, reduce the sludge surface area ratio. Surface area, chemicals that destroy the structure of bacteria. The main components are inorganic compounds, sludge surface structure modifier, degreaser, wall breaking agent, sludge surface treatment agent, sludge stripping agent and so on. Theadvantages of sludge dehydrating agent compared with traditional dehydrating agent are:

1. can effectively reduce the moisture content of sludge, so that the sludge depth dehydration.

2. the water content in the sludge can be reduced to 35%-55%, and the sludge weight reduction effect is good.

3. The mud press efficiency of plate and frame filter press is increased by 100%-500%, and the mud press cycle is greatly shortened.

4. the amount of sludge dehydrating agent added is small, no need to add lime, sludge conditioner does not contain chloride ions, does not corrode dewatering equipment.

5. sludge deep dehydration, is conducive to the subsequent incineration of sludge, brick, compost.

6. sludge deep dehydration of non-stick filter cloth, reduce the frequency of dewatering equipment to replace the filter cloth, saving operating costs.
