Dewaterer for Sewage Screenings - SPIROWASH®

Supplier: SPIRAC

When fine screens are installed in municipal Waste Water Treatment Plants, they generate large volumes of faecal and organic matter from screening activities. Typically, a washer dewaterer washes out the organic material, reduces the volume and weight of the screenings and compacts them.

Price Guide: POA

WHAT IS THE SPIROWASH®

The SPIROWASH represents a range of machines available to handle raw screenings flows of up to 2 m³/hr. The machine continuously washes out organic material whilst mechanically compacting and dewatering the remaining inorganic portion.

The SPIROWASH® is a robust and simple machine, non-sensitive to varying qualities of screenings and contents of grit.

The SPIROWASH® is designed so that maintenance to all moving parts can be completed from the outside of the machine – no bearings, wheels and lubrication points are inside.

The machine can be located either directly underneath the screen or fed by a conveyor. If a launder feed is necessary a special model is on hand to deal with great volumes of free water.

The SPIROWASH®  is ideally suited to applications – also retrofits – where its capacity, robustness, compact size and cleaning/compacting qualities make an obvious step up to meet tomorrow’s rigorous requirements.
