During the deep dewatering process of sludge, numerous industrial enterprises and municipal wastewater treatment plants have encountered the embarrassing situation of "false dryness with a soggy core": even when the pressure of the belt press filter was maximized and the pressing time was extended, after cutting open the sludge cake, one could still see a damp and soft "soggy core" inside. This kind of sludge cake that is dry on the outside but wet on the inside is not only difficult to meet the national environmental protection standards of a moisture content of less than 60%, but also极易 causes water seepage and leakage during transportation, polluting the transportation vehicles and the road surface, creating secondary environmental hazards; at the same time, the high moisture content sludge cake will also cause great obstacles to subsequent resource disposal methods such as landfill and incineration, increasing the disposal cost and difficulty, and even可能导致 the enterprise's environmental protection verification to fail, affecting normal production and operation.

Going back to the source, the traditional PAC, PAM and other conventional conditioning agents have obvious technical shortcomings: These agents can only act on the surface particles of the sludge, quickly forming a dense and hardened shell. It seems that the sludge has been "dried", but in fact, it blocks the water-permeable channels inside the sludge, preventing the internal water from being discharged normally. Eventually, a "false-dry" state is formed, with dry surface and damp interior. This state cannot meet the environmental protection requirements for deep sludge dewatering in the long term, nor can it fundamentally solve the "soft core" problem.
In response to this industry challenge, Works Chemical Co., Ltd. has developed a sludge enhancer that incorporates advanced osmotic pressure modification technology. This technology completely breaks through the limitations of the surface effects of traditional chemicals. This product can rapidly disintegrate the high-viscosity gel layer on the surface of the sludge, open up the water-permeable channels within the sludge, and achieve uniform water evaporation from the inside out, thereby fundamentally preventing the occurrence of the "soft core" false-drying phenomenon. At the same time, the adaptability of the sludge enhancer is extremely strong. It can flexibly adapt to various sludge systems with high organic content, high viscosity, and complex compositions. There is no need to modify the existing equipment, and it can be put into use quickly.
A large amount of on-site application data shows that after using the sludge enhancer, the dryness of the sludge cake inside and outside is uniform and consistent, completely eliminating the "soft core" problem. The moisture content of the sludge cake can be stably controlled within the range of 50% - 60%. In some working conditions, it can achieve deeper dehydration at a lower depth. Compared with traditional chemicals, the moisture content directly decreases by about 20%. This effect not only effectively avoids environmental risks such as transportation leakage and secondary pollution, but also meets the disposal policy requirements for solid waste reduction and harmless treatment. It helps enterprises easily pass environmental protection inspections, reduce the subsequent pressure of sludge disposal, and at the same time reduce disposal costs, achieving a dual improvement of environmental protection and benefits.
