After the remaining sludge is dewatered by a belt filter press (with a water content of about 80%), it is modified by adding a skeleton agent or modifying agent, and then enters a high-pressure belt filter press for secondary deep dewatering treatment, making the water content of the sludge reach 60% - 70%.

Technological advantages 

It can be effectively compatible with the original belt filter press system, without affecting the normal operation of the original wastewater treatment plant, saving investment; Different sludge modifications can be carried out according to different sludge disposal requirements such as subsequent landfilling, incineration, low-temperature drying, and composting; Small footprint, convenient operation, and stable operation; Continuous automatic operation, with little or no manual participation; Process equipment control is simple, installed power is low, and energy consumption is saved.
