The sludge produced by municipal sewage treatment plants, due to its wide sources and complex composition, has become a "challenge" in the process of sludge dewatering treatment. This type of sludge has a high organic matter content, a high colloid viscosity, and numerous impurity components. It not only contains suspended particles from domestic sewage but also contains a large amount of microorganisms and organic substances. The dewatering treatment is much more difficult than that of ordinary industrial sludge. Nowadays, environmental protection regulations in China are becoming increasingly strict, and many places have raised higher requirements for the disposal of municipal sludge. Generally, it is clearly stipulated that the moisture content of the sludge should be below 60%, and in some key areas, it is even required to be below 40%. Traditional single-chemical agents and conventional dewatering processes have long been unable to meet this deep dewatering standard.

Facing strict environmental protection standards, many municipal sewage treatment plants can only rely on post-treatment thermal drying equipment for secondary drying to reduce the moisture content of the sludge. However, the thermal drying equipment not only has a huge initial investment but also comes with high energy consumption and high operation and maintenance costs. During operation, it requires a large amount of electricity and heat energy, significantly increasing the operational burden of the sewage treatment plant. At the same time, it does not conform to the concept of green and low-carbon development. Therefore, finding a chemical solution that does not require additional equipment and can achieve one-time deep dehydration has become an urgent need for municipal sewage treatment plants.

Works Chemical Co., Ltd. precisely meets the treatment requirements of municipal sewage plants by developing a sludge enhancer. This product innovatively adopts a triple synergistic mechanism of "electro-neutralization + adsorption bridging + surface modification", breaking through the limitations of single-function of ordinary chemicals and achieving the ultimate effect of sludge-water separation. This product can deeply destroy the stable structure of sludge colloids, remove the bound water and adsorbed water on the surface of sludge particles, convert the difficult-to-separate bound water into freely discharged water, and fundamentally improve the dewatering efficiency and effect.

Relying on this core technical advantage, the sludge enhancer can complete the deep dehydration of municipal sludge on conventional plate and frame filter equipment in one step. No additional thermal drying equipment is required, and no complex process modification is needed. This significantly reduces equipment investment and energy consumption. In practical applications, this product can stably control the moisture content of municipal sludge below 60%, and in some cases, it can reach an ultra-low standard of below 40%. It can not only meet the strict environmental disposal requirements but also simplify the treatment process and reduce operational pressure. The sludge enhancer helps municipal wastewater treatment plants implement the green and low-carbon operation concept, achieve the reduction, harmless treatment, and stabilization disposal of sludge, and conform to the overall planning of urban ecological environmental construction, contributing to urban environmental governance.
