WASTEWATER PRESS SCREW SEPARATOR FA/PSS SERIES
The wastewater press screw separator comprises a wedge wire screen basket to capture the suspended solids, which are removed by a rotating screw having a very small tolerance between the screw flights and the screen basket surface. As the solids are pushed towards the discharge end, they form a plug in the compaction zone where dewatering takes place. Two adjustable metal flaps located at the discharge-end provide the counter-pressure to form the plug and control the degree of dewatering to take place. This machine is extensively used in the paper mills, but works equally well with any fibre-based solids. To treat very fine suspended particles, we recommend using a polymer as a flocculant to enhance the dewatering properties of the sludge.
Features:
- Separation of suspended solids from liquid flows
- Fixed screen drum captures suspended solids
- Rotating screw removes solids from screen surface and transports solids to compaction zone
- Solids discharge axially into receiver bin or conveyor
- Compaction of solids before discharge
- Dryness controlled by adjustable pressure in compaction zone
- No washing in the screen zone
- Optional flushing system
