For the problem of too thin and unformed sludge after mud pressing, the following are some effective solutions:

Increase sludge solid content:

If the solid content of the sludge is too low, the solid content of the sludge can be improved by increasing the sludge thickening process or optimizing the thickening process.

The use of belt mud press or sludge thickener can effectively increase the sludge concentration, making it more suitable for filtration treatment.

Select the right sludge conditioner:

Select the appropriate sludge conditioner according to the nature of the sludge (such as acid-alkaline, organic/inorganic sludge, etc.).

Ensure that the type and amount of sludge conditioner are correct to achieve the best sludge dewatering effect.

The sludge conditioner should be fully mixed with the sludge to avoid the formation of false floc.

Optimization of sludge flocculation process:

The flocculation effect of sludge directly affects the mud pressing effect. Ensure that the flocculant is stirred evenly to avoid local concentrations that are too high or too low.

Adjust the dosage of flocculant according to the change of sludge concentration in time to maintain the best flocculation effect.

Cleaning cloth and filter plate:

Clean the filter cloth and filter plate regularly to prevent blockage from affecting the filtering effect.

Check the integrity of the filter cloth and filter plate, and replace it in time if it is damaged.

Adjust feed pressure and feed pump:

Ensure that the feed pump is working properly and provides sufficient feed pressure.

If the feed pressure is insufficient, check whether the feed pump is faulty or blocked, and repair or replace it in time.

Replace the appropriate filter press:

If the filter press type is not selected properly, it may also lead to the sludge pressing mud is not formed. The suitable filter press type should be selected according to the nature and capacity of sludge.

Consider the water filtration of the sludge:

Poor water filtration and large specific resistance of sludge will also affect the mud pressing effect. The water filtration can be improved by adding filter aid or improving the properties of sludge.

In summary, to solve the problem of too thin and unformed sludge after mud pressing, it is necessary to start from many aspects, including improving the solid content of sludge, selecting the appropriate sludge conditioner, optimizing the sludge flocculation process, cleaning the filter cloth and filter plate, adjusting the feed pressure and feed pump, replacing the appropriate filter press and considering the filter water of the sludge. Through the comprehensive policy, the sludge press filtration effect can be effectively improved and the treatment cost can be reduced.
