The papermaking industry generates a large amount of sludge during the production process. This sludge has a high water content, large volume and is difficult to treat. How to achieve efficient and deep dewatering of papermaking sludge has become one of the difficult problems faced by papermaking enterprises. The emergence of sludge enhancers has provided an effective solution to this difficult problem.

The working principle of sludge enhancers

Sludge enhancers mainly change the surface properties of sludge particles through chemical reactions, destroy the colloidal structure in sludge, and release bound water. Meanwhile, it can also enhance the bridging effect between sludge particles, form larger flocs, and improve the dewatering performance of sludge. In the treatment of papermaking sludge, sludge enhancers can better coagulate the fibers and fillers and other components in the sludge, facilitating subsequent dewatering operations.

The application effect in deep dewatering of papermaking sludge

Sludge with a moisture content originally as high as 80% to 90% can have its moisture content reduced to below 60% after treatment, significantly reducing the volume of the sludge and lowering the cost and difficulty of subsequent treatment.

Youdaoplaceholder0 Enhance dewatering efficiency ‌ : Sludge enhancers can improve the dewatering performance of sludge, significantly increasing the dewatering efficiency of dewatering equipment such as plate and frame filter presses and belt filter presses. Within the same period of time, more sludge can be processed, which improves the operational efficiency of the entire sludge treatment system.

This is conducive to the storage and transportation of sludge and also provides better conditions for its subsequent resource utilization.

A large-scale papermaking enterprise generates a large amount of papermaking sludge every day. When using traditional dewatering methods, the moisture content of sludge remains high and the dewatering efficiency is low. Later, the enterprise introduced sludge enhancers for experimentation. After a period of trial use, it was found that the moisture content of the sludge had significantly decreased, and the operational efficiency of the dewatering equipment had increased by more than 30%. Meanwhile, the treated sludge has stable properties and is convenient for subsequent resource utilization such as incineration for power generation or fertilizer production.

Sludge enhancers have a remarkable effect in the deep dewatering of papermaking sludge. It can reduce the moisture content of sludge, enhance dewatering efficiency and improve sludge properties, providing effective technical support for sludge treatment in papermaking enterprises. With the continuous improvement of environmental protection requirements, the application prospects of sludge efficiency enhancers in the papermaking industry will be even broader.
