In the daily operation of the plate and frame filter press, the sludge treatment effect is directly related to the stability of the subsequent process and the treatment cost. However, many operators encounter a thorny problem: the mud cakes pressed out are not dry, stick to the filter cloth, and even have a runny core. These problems not only reduce the processing efficiency, but also increase the frequency of filter cloth replacement and equipment maintenance costs. So, is there an effective solution? The answer is - sludge enhancer.

Analysis of Common Problems in Plate and Frame Mud Pressing

The ‌ mud cake is not dry ‌ : the moisture content of the mud cake is too high, which makes subsequent treatment difficult, such as increased energy consumption during incineration and easy generation of leachate during landfill.

Youdaoplaceholder0 Sticky filter cloth ‌ : Sludge adheres to the filter cloth, making it difficult to clean, which affects the service life of the filter cloth and simultaneously reduces the filtration efficiency.

Youdaoplaceholder0 mud cake runny center ‌ : The water inside the mud cake has not been fully drained, resulting in a "runny center" phenomenon, which leads to low strength and easy breakage of the mud cake.

These issues are usually closely related to the nature of the sludge, the dewatering process and the selection of additives. Traditional dewatering agents such as polyaluminium chloride (PAC) and polyacrylamide (PAM), although they can improve the dewatering effect to a certain extent, often seem inadequate when dealing with high-viscosity and difficult-to-dewater sludge.

Sludge enhancer: A powerful tool for solving the problem of sludge pressing by plates and frames

Sludge enhancer is a highly efficient additive specially developed for sludge dewatering processes. By improving the dewatering performance of sludge, it fundamentally solves problems such as non-drying, sticking to the filter cloth, and the runny core of the sludge cake that occur during the plate and frame sludge pressing process.

Youdaoplaceholder0 Enhance dewatering efficiency ‌ : Sludge enhancers can significantly reduce the specific resistance of sludge, making it easier for water to separate from the sludge, thereby improving dewatering efficiency and reducing the moisture content of the sludge cake.

Youdaoplaceholder0 Reduce adhesion phenomenon ‌ : The sludge enhancer can change the charge properties on the surface of sludge particles, reduce the adhesion force between sludge and filter cloth, and thus effectively prevent the problem of filter cloth sticking.

Youdaoplaceholder0 Improve the structure of the sludge cake ‌ : The sludge enhancer can promote the aggregation and sedimentation of sludge particles, forming a compact and high-strength sludge cake, and prevent the occurrence of a runny center in the sludge cake.

 

In the face of problems such as non-drying, sticky filter cloth and runny mud cake during the plate and frame sludge pressing process, choosing the appropriate type of sludge enhancer is undoubtedly the best solution. It can not only significantly improve the dehydration efficiency, but also reduce the operating cost and extend the service life of the equipment. Therefore, in the field of sludge treatment, sludge enhancers are gradually becoming the preferred additives.
