WASH-COMPACTOR

High Efficiency Screenings Washing Equipment

  • Ideal for fine screen installations producing large quantities of faecal solids.

  • Wash-compactors are ideal for raw sewage or sludge screenings and the waste product is easily disposed of

  • Good BOD reduction is achieved.

  • Available in seven sizes for a range of capacities from 0.68m/hour.

Waste solids are collected by screens and discharged into a launder or conveyor, These solids are delivered to the Wash-compactor. If a conveyor is used, then water is added to the washing tank separately.

Washing is performed by converting the energy from the impeller motors into high rate turbulence. This turbulence has the ability to break down or liquefy the faecal materials and "any other soft solids present in the collection of debris.

The displacement created by the incoming water together with the energy surges provided by the impeller/s, encourages the water and washed solids to over-spill into the channel that delivers to the on-board screw compactor.

A perforated U trough houses the screw and acts as a fine screen or sieve to drain off the dirty washing water. The solids are retained and are conveyed to the dewatering zone of the compactor equipment. Clean water is introduced to the screenings at this point. The clean water floods over the solids and acts as a rinse to eliminate the residual dirty wash water, so that clean screenings can enter the compaction and delivery section of the machine.

Transportation to the awaiting collection vessel is through an inclined chute. The accumulated material within the chute provides the back pressure required for the satisfactory dewatering of the material.

Capacities

The capacities stated below are the volumes of screened material from the given screening equipment. The volumes are given as a rate per hour. The delivery of the screenings material will be assumed to be as near to continuous as possible. In those cases where the screens are at rest for long periods, and with large, single raking mechanisms, it may be necessary to size-up the Wash-compactor unit to enable it to deal with the large instantaneous loading.

Information For Proposals

* Rate of screenings production or details of size, number, bar space and flow rate of the screens that produce the solids.

* Height of the screen discharge relative to the floor level for mounting the Wash-compactor/s.

* Location of the Wash-compactor relative to the screen and the washed screenings collection.
