Sludge treatment performance is greatly
improved with TFU
This model has two thickening functions in the filter element and flocculation tank.
When the water content of the dewatered cake is set at the same level as that of the conventional machine, the throughput is improved by approximately 50%.
Preventing overload stoppage that delays dewatering
Equipped with the stable operation support control VAS (VOLUTE™ Antilock system), this design prevents overload stoppage, which may reduce hourly throughput.
Constantly monitoring the current value of the screw motor, this function controls the screw speed properly to ensure stable dewatering.
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 moving ring, driving the moving ring to clean the filter element gap.
The design 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.
PROCESS FLOW
-
01
Flow Control Tank
Sludge feed is regulated with the overflow pipe, returning excess volume to the sludge storage tank. -
02
Thickening Flocculation Tank
Polymer and sludge are stirred and mixed, forming flocs suitable for VOLUTE™. Then, the built-in thickener in the tank instantly thicken the sludge. -
03
Cylinder Unit
Sludge is further thickened in the thickening zone of the cylinder, and then the inner pressure increased at the dewatering zone helps sludge being dewatered well. -
04
Discharge Outlet for Dewatered Cake
Further pressure is applied from the outlet side with the end plate, discharging dewatered cake with 20% (+/-5%) dry solids content.
