The water content of the mud pressed out by the filter press is very high, and the mud is very thin, and the reasons need to be analyzed from several aspects. Such as the plate and frame machine, whether there is a bad water permeation problem of the equipment, the use of dehydrating agent does not match, the sludge is not conditioned and so on, only know the clear reason to solve the problem.

1. The filter cloth is blocked.

The clogging of the filter cloth makes the filter water is not good, and the mud is not well separated from the water, so the mud is very thin and the moisture content is very high.

The solution is to replace the filter cloth.

2. the use of dehydrating agents do not match.

The sludge dehydrating agent used does not match the mud, does not break the wall of the sludge cells well, and the water is not pressed and filtered well, so the mud is very thin and the water content is very high.

The solution is to replace the sludge conditioner that is better at breaking the wall of the sludge cells.

3. the sludge is not conditioned.

The sludge entering the filter press has not been conditioned, making the filter press filter effect is not good, so the mud is very thin and the water content is very high.

Solution Before the sludge enters the filter press, an agent is added to the conditioning tank for conditioning.

 

4. improper maintenance of the filter press.

The daily maintenance of the plate and frame filter press is improper, resulting in the filter plate is not well maintained, the filter plate is deformed, and the filter cloth is damaged, which will affect the normal work of the filter press, resulting in very thin mud and high moisture content. The solution is to carry out regular maintenance on the plate and frame filter press and replace the broken filter cloth and filter plate.

5. the filter plate assembly is not correct.

The filter plate is not assembled correctly, so that the filter cloth can not fit well on the filter plate, which will lead to poor filtration effect, very thin mud, and high moisture content. The solution is to check and correct the assembly of the filter plate to ensure that the cloth is fitted to the filter plate.

6. the pump is not working normally.

The front pump of the plate and frame filter press is not working normally, such as the insufficient flow of the pump or the insufficient pressure of the pump, which will lead to the sludge entering the filter press is not well concentrated, affecting the filter press effect, resulting in a very thin mud and a high moisture content. The solution is to check the working condition of the pump and repair or replace the pump if necessary.

7. the filter press working pressure is insufficient.

The working pressure of the plate and frame filter press is insufficient, and the water in the sludge can not be effectively discharged, resulting in very thin mud and high moisture content. The solution is to adjust the working pressure of the filter press so that it reaches the appropriate value.

8. The sludge is unstable.

The sludge entering the plate and frame filter press is unstable in nature, such as containing too much organic matter or containing too much clay, which will affect the filter press effect, resulting in very thin mud and high moisture content. The solution is to pretreat the sludge before entering the filter press, such as adding agents such as oxidants to improve the properties of the sludge.
