Our 24 Hours Automatic Volute Screw Press Activated Sludge Dewatering Machine is a high-efficiency solid-liquid separation equipment engineered for continuous sludge thickening and dewatering in various industrial and municipal wastewater treatment facilities. Unlike traditional belt filter presses and centrifuges that rely on filter cloths or high-speed rotation, our innovative multi-plate screw press design eliminates clogging issues, reduces operational costs by up to 60% and enables 24/7 unattended operation. It can handle all types of sludge with densities ranging from 10000mg/L to 50000mg/L, especially oily sludge that is difficult to treat with conventional methods, making it the ideal choice for enterprise users seeking reliable and cost-effective sludge treatment solutions.
Our volute screw press sludge dewatering machine is universally applicable to sludge generated from municipal wastewater, food and beverage processing, slaughtering and breeding, printing, petrochemical engineering, papermaking, tannery and pharmaceutical industries. Its innovative structure design allows it to effectively dewater both high and low density sludge, and it is particularly outstanding in treating oily sludge, earning it the reputation as the ultimate solution for oily sludge dewatering.
Equipped with special dynamic and static annular rings instead of traditional filter cloths, our sludge dewatering machine features excellent self-cleaning performance and is not prone to clogging. This eliminates the need for extensive high-pressure washing to prevent filter gap blockage, significantly reducing cleaning water consumption by up to 80% and solving the persistent clogging problem that plagues traditional dewatering equipment.
The entire dewatering process, including sludge pumping, chemical dosing and sludge cake discharge, is fully automated and controlled by an integrated electrical cabinet. The system works seamlessly with polymer feeders, sludge feed pumps and polymer feed pumps without any manual intervention. It can operate continuously around the clock without interruptions caused by clogging or abnormal filter operation, and daily maintenance is simple and convenient.
Our compact and integrated design greatly reduces operational expenses for commercial enterprises. The low-speed spiral pressing technology (only 2-3 revolutions per minute) cuts power consumption by more than 70% compared to centrifuges. The non-clogging design minimizes cleaning water usage, and fully automatic operation eliminates the need for dedicated operators, reducing labor costs by up to 70%.
With a screw shaft rotation speed of only 2-3 rpm, the machine operates with no vibration and extremely low noise. Its self-cleaning function requires only a small amount of water for maintenance, preventing secondary water pollution. The slow dewatering process also prevents odor diffusion, creating a clean and comfortable working environment for your staff.
The machine adopts a flexible and durable frame design based on mechanical extrusion principle, eliminating the need for large drum structures. Almost all components are made of high-quality stainless steel SS304 or SS316 for excellent corrosion resistance. The only replacement parts are the screw shaft and moveable annular plates, ensuring a long service life and low maintenance costs.
Unlike traditional dewatering equipment that requires separate sludge thickening units, our volute screw press integrates both thickening and dewatering functions in one unit. It can directly treat aerobic sludge from aeration tanks, eliminating the need for thickening storage tanks. This reduces the required space for sewage treatment facilities by up to 50% and cuts construction costs significantly.
The sludge dewatering process is carried out under aerobic conditions, which prevents phosphorus release from sludge that occurs in anoxic or anaerobic environments in traditional sludge thickening tanks or storage tanks. This significantly improves the overall phosphorus removal efficiency of your wastewater treatment system.
Our multi-plate screw press dewatering machine consists of multiple fixed annular plates and moveable annular plates stacked alternately, with a screw shaft running through the entire assembly. The machine is divided into two functional sections: the front thickening department and the rear dewatering department.
Sludge is first fed into the thickening department through the inlet. As the screw shaft rotates, the sludge is transported forward while the filtrate flows out through the gaps between the annular plates. The sludge is gradually thickened as water is removed.
The thickened sludge is then transported to the dewatering department. As the sludge advances, the filter spacing and screw pitch gradually decrease, and the back platen creates additional resistance. This generates enormous internal pressure, causing the sludge volume to continuously decrease and more water to be squeezed out. Finally, the fully dewatered sludge cake is discharged from the exit.
The relative movement between the fixed and moveable annular plates during operation continuously cleans the filter gaps, preventing clogging and ensuring stable and continuous dewatering performance.
