TPDL volute screw sludge dewatering machine is a new technology of
Sludge Dewatering Machine(Hereinafter referred as TPDL) which
belongs to the screw press, can replace the traditional filter
press like belt press and frame press. It's clog-free and can
reduce the sedimentation tank and sludge thickening tank, saving
the cost of sewage plant construction.
Usage of volute screw press sludge dewatering machine
•Municipal & Domestic
•Tannery•Paper & Pulp•Dyeing & Printing
•Food & Beverage•Dairy•Agricultural•Slaughter & Farming
•Pharmaceutical & Petrochemical
Working principle of volute screw press sludge dewatering machine
The wastewater is pushed into the dewatering machine.The sludge
will move to the sludge cake outlet under the pressure of the
helical aixs blades. Becuse the gap among the helical blades become
narrower,so the sludge bear heavier pressure and began to
dewatering under the pressure. The water comes out from the space
between fixed and moving plates.
Advantages of volute screw press sludge dewatering machine
1. Low operation cost: below 40% of belt press and 20% of
centrifuge.
2. Power-saving: less than 5% of centrifuge
3. Water-saving: less than 0.1% of belt filter press.
4. Saving drugs: saving around 60%.
5. Compact: saving more than 60% of the investment for dehydration
room.
6. Non-clogging: processing the fats & oils and fiber sludge
perfectly.
