The key issue in the deep filtration of sludge using plate and frame presses often lies not in the equipment pressure, but in the nature of the sludge itself. The sludge has a stable colloidal structure and its moisture is tightly bound. Conventional iron salts and aluminum salts have limited effects and are unable to fundamentally break this state. This is the main cause of problems such as excessive moisture content in the sludge cake, poor drying during sludge pressing, and internal soft spots in many on-site situations.

The new generation of polymer sludge enhancer adopts an innovative formulation process, integrating three functions: conditioning, flocculation, and dewatering. It optimizes the entire process of plate and frame filtration based on its mechanism of action, and can be widely adapted to various working conditions.

The sludge enhancer contains exclusive components that can damage the microbial cell membranes and the stable sludge colloid system, effectively releasing the intracellular water and bound water that are difficult to separate. It converts the bound water into easily removable free water, achieving water reduction and viscosity reduction from the source. At the same time, the product's high-molecular long-chain structure can quickly adsorb and gather small sludge particles, forming dense and compact large flocs, preventing fine particles from blocking the filter cloth and ensuring the smoothness of the filter press drainage channels. During the high-pressure filter stage, the formed flocs have high mechanical strength and are less likely to collapse, with water being released uniformly and rapidly. The resulting sludge cake is regular in shape, completely solving the problems of soft core and runny center.

This product can be used independently and fully replaces traditional iron salt and aluminum salt combined agents. The process flow is simple and it has extremely strong versatility. After being verified through numerous on-site applications, the moisture content of the treated sludge remains stable and meets the standards. The comprehensive efficiency of the filter press is increased by more than 40%. It can also reduce the dosage of chemicals and decrease the increase in sludge volume. It achieves a balance between treatment efficiency, environmental compliance and operating costs. It is the preferred solution for deep filtration of municipal and industrial sludge using plate and frame filters.
