Sludge compaction is a common problem in the sludge treatment process. As a sludge conditioner manufacturer, we have a deep understanding of the causes and solutions of sludge compaction. The following is a detailed analysis of the problem:

First, the reason for the sludge pressure

Sludge conditioner selection error:

Different sludge properties require different sludge conditioners. If the selection is not appropriate, it may lead to the sludge can not be effectively flocculated, thus affecting the dehydration effect.

Insufficient or excessive amount of sludge conditioner:

When the addition amount is insufficient, the flocculation effect of sludge is poor, and the moisture content is high; When too much is added, the sludge may become too viscous and easily stick to the filter cloth or clog the filter cloth.

Improper design or operation of sludge settling tank:

If there is no reflection tank for sludge and sand washing agent above the sludge settling tank, the reaction time of sludge and agent is too short, and the settling speed is slow.

The sludge flow rate before entering the filter press is unstable:

The unsteady flow rate may lead to uneven mixing of sludge and reagent, and the true separation of sludge and water cannot be achieved.

Equipment problem:

Filter press equipment failure, such as feed pump failure resulting in insufficient feed pressure, filter cloth selection error or cleaning is not clean, may affect the dehydration effect.

Changes in sludge properties:

Changes in external factors, such as upstream process, temperature, acid and alkali, etc., may lead to changes in sludge properties, thus affecting the sludge conditioning effect.

The sludge is too fine, too sticky or the organic matter content is too high:

These factors may lead to the sludge surface and interstital water difficult to escape, thus affecting the dehydration effect.

Two, sludge pressure solution

Correct selection of sludge conditioner:

Select the appropriate sludge conditioner according to the nature of the sludge and the requirements of the dewatering equipment. If necessary, technicians from sludge conditioner manufacturers need to go to the site to do new type selection experiments.

Strictly control the amount of sludge conditioner added:

According to the experimental results and process requirements, the addition amount of sludge conditioner is strictly controlled to ensure that the coagulation and flocculation effect of sludge reach the best state.

Optimization of sludge settling tank design:

A reflection tank is set above the sludge settling tank to prolong the reaction time of the sludge and the reagent and improve the settling speed.

Stabilized sludge flow rate before entering the filter press:

By adjusting the parameters of the pipeline and pump, the flow rate of the sludge before entering the filter press is stable, so as to achieve the uniform mixing of the sludge and the agent.

Regular inspection and maintenance of filter press equipment:

Check the feed pump, filter cloth and other parts of the filter press regularly to ensure their normal operation. At the same time, clean the filter cloth regularly to avoid clogging and wear.

Adjusting sludge treatment process:

According to the change of sludge properties, timely adjust the sludge treatment process, such as adding appropriate diluent or adjusting the treatment process parameters.

Select the appropriate desliming equipment:

According to the nature of the sludge and dehydration requirements, choose the appropriate desilting equipment, such as plate and frame filter press, belt filter press, etc.

In summary, the reasons for sludge compaction may involve many aspects, including the selection of sludge conditioner, the amount of addition, the design of sludge settling tank, the flow rate of sludge, equipment problems and the nature of sludge. In order to solve this problem, it is necessary to start from multiple angles, consider various factors comprehensively, and take corresponding measures to optimize and adjust.
