After concentrating process of coagulated sludge in primary thickener, sludge flows into screw press .
It is dewatered by compressive force of screw press which is generated by taper shape and random pitch.
Screw press maximizes dewaterablity by increasing open porosity.
Energy saving with low power operation
Reduction of dehydrated cake by lower moisutre content
Cake moisture content & throughput adjustment
Stable dehydration inlet concentration change(0.8~6%)
Prevention of noise & vibration with low speed operation
Simple structure easy maintenance
Cleaning water quantity reduction
