Sludge dewatering agent (sludge conditioner) instead of lime in sludge treatment process has significant advantages, especially in reducing the moisture content of mud cake. Here's a clear answer to the topic:

Advantages of substituting lime

Moisture reduction:

The use of sludge dehydrating agent (sludge conditioner) can effectively reduce the moisture content of sludge. Compared with lime, dehydrating agent has lower water content and can better promote the dewatering process of sludge.

The use of sludge dehydrating agent (sludge conditioner) after the conditioned sludge through the plate and frame filter press filtration, can effectively reduce the moisture content of the sludge to 35%-55%.

Stability:

Sludge dewatering agent (sludge conditioner) has good stability and can keep the moisture content of sludge below 60%.

This stability not only reduces the difficulty of processing, but also helps to maintain the ongoing effectiveness of the processing process.

Cost savings:

The cost of using lime is high, and the use of sludge dehydrating agent (sludge conditioner) can reduce the operating cost of enterprises.

Due to its excellent dehydration effect and stability, the dehydration cycle can be shortened by about 10%, further reducing the operating cost.

Environmentally friendly:

The use of lime may cause a certain pollution risk to the environment, and the sludge dehydrating agent (sludge conditioner), as a new sludge treatment agent, has less impact on the environment.

The use of sludge dehydrant can also reduce the production of lime mud, reduce the sludge increment, and reduce the pressure on the environment.

The concrete effect of decreasing water content of mud cake

Through the use of sludge dewatering agents (sludge conditioners), combined with dewatering equipment such as plate and frame filter presses, the moisture content of the sludge can be reduced from a higher level (such as more than 90%) to a lower level (such as 40%-60%, or even lower to 35%-55%).

This significant reduction in water content not only reduces the volume and weight of the sludge, but also improves the dryness of the sludge and the possibility of resource utilization.

Sum up

Sludge dehydrating agent (sludge conditioner), as a new sludge treatment agent, has obvious advantages in replacing lime. By reducing the moisture content of sludge, improving stability, saving costs and environmental friendliness, it has brought new hope and options for the sludge treatment industry.
