screw press / dewatering
The SDE 315 has been designed by HAUS for dewatering in waste water treatment facilities and ensures obtaining high dryness.The SDE 315 is a screw press: inclined bowl with made of moving and stationary discs, continuous discharging of sludge through screw conveyor, variable screw speed and torque power. SDE 315 adjusts compression rate in accordance with amount of solid. SDE 315 consist of the appurtenances made out of moving and stationary discs, strong chasis that support appurtenances and safety components. The appurtenances made out of moving and stationary discs allow easy cleaning and prevent clogging. The Screw has a gradually narrows design to ensure more infiltration in the begining and more compression in the end. SDE 315 have an extra bunker for muddy water which infiltrates at the last sector. That muddy water can be pumped to the condensing tank. Five point washing system which is automatically controlled, ensures the bowl is always clean with small amount of water. The motor is driven by frequency converter, which allows smooth start/stop, rotational speed regulation and power control. The solid ouput automatically controlled by pneumatic pistons to arrange variable solid content extraction to ensure high dryness with low energy consumption.
