Volute - Model EC Series -Dewatering Press

No clogging even with oily sludge

• The machine has a filter element that consists of alternating layers of rings fixed at four locations (fixed rings) and vertically movable rings (moving rings) maintaining a gap between them, and a single screw that is threaded through the filter element to transfer and compact the sludge.
• A clog-free self-cleaning mechanism is achieved since the screw rotates at a constant speed in contact with the floating ring, driving the floating ring to clean the filter element gap.
• The machine delivers stable dewatering performance even with oily sludge.
• The amount of cleaning water for preventing clogging is very small compared to other types of dewatering machines.

No pre-thickening required

• This machine has an integrated structure in which two processes, thickening and dewatering, are handled by a single filter element, allowing the user to directly charge low-concentration sludge having a TS of about 0.2% without providing a thickening system in the preceding stage.
• This not only reduces the construction and operating costs for the thickening and storage systems but also reduces odor because aerobic sludge is dewatered.
• The machine can also efficiently capture phosphorus in waste activated sludge to the dewatered cake side, reducing the load caused by phosphorus returning to wastewater treatment.
