Vertical Spiral Sieve DF SP

Functioning:

The wastewater enter the device through the inlet chamber, where they get loosened and slowed down. The inlet chamber is also the emergency overflow in the event of excessive wastewater flow or power breakdown. The fluid flows to the cylindrical filtering basket, where sold bodies are separated.

The screenings held on the internal surface are removed by the sweeping brushes system assembled on the worm conveyor. The contamination is transported with worm conveyor to the upper segment of the device from where it is transferred to the discharge mechanism.

The sieve drive is automatically engaged with proper level of wastewater collected. The screenings are drained when transported and their weight is reduced thanks to compression-drainage block equipped with automatic flushing system. Extended knife gate valve pin enables operation without human presence in the sieve chamber.
