Municipal sewage/sludge dewatering, rural domestic sewage, biochemical sewage, physicochemical sewage, tap water sludge treatment, river dredging sludge dewatering

In response to the current situation of high moisture content in sludge cake filtered by traditional reinforced polypropylene plate filter presses, Sudong has developed a special filter press for deep sludge dewatering based on the characteristics of sludge. This series of filter presses uses imported polymer TPE elastomer formula to produce high-pressure diaphragm filter plates, with a pressing force of up to 3MPa. By secondary pressing the filtered cake, the moisture content of the cake can be reduced to around 55%. Under the premise of economy, safety, and environmental protection, centralized disposal and resource utilization of sludge have been achieved, achieving "reduction, harmless, stable, and resource utilization" of sludge.

The investment and operating costs of sludge treatment account for 25% -65% of the total investment and operating costs of the entire sewage treatment plant, which has become a heavy burden faced by urban sewage treatment plants. Generally, sludge reduction treatment accounts for about 60% of the total investment in sludge, and the most important aspect of sludge reduction is sludge dewatering. The current use of Sudong filter press is an economical and environmentally friendly dehydration method that is of great significance for sludge treatment and disposal.

Fully automatic and efficient filter press, high-pressure diaphragm filter press

Adopting a mechatronics hydraulic integrated design, PLC program control, equipped with a flip plate liquid receiving device to collect filter cloth capillary water and filter cloth cleaning water, equipped with a filter cloth automatic cleaning system, no dead corners when washing filter cloth, equipped with a mud cake collection device and sludge conveying equipment, system integrated control, high degree of automation, convenient operation, safety and reliability; The working filtration pressure can reach 1.6MPa, and the pressing pressure can reach 2.5MPa. The filtration efficiency has been improved, and the moisture content of the mud cake after filtration is below 55%.
