• On arrival at the plant, the vehicle would reverse and discharge directly into the WT-100 Unit.  If the unit is located at ground level, access is via ramp either fabricated from steel (see photo) or built up using granular fill.  Feed material can also be loaded via a telehandler type machine at low level if a wedge pit type operation is preferred. 

 

• The material in the V shaped hopper is conveyed using a horizontal auger to the bucket wheel section of the unit.  The solids are then transferred into a 10mm wet trommel, for washing and separation of a grit fraction from the oversize material.

 

• The minus 10mm grit fraction is dewatered and discharged from the unit using an inclined auger where it is given a further rinse along the auger.

​

• The oversize material from the wash process is dewatered and discharged from the unit using an open chevron type conveyor.

 

• The fine solids laden water  from the unit is first passed over the dewatering screen (to remove any minus 10mm organic products) before being forwarded to the water treatment plant.
 

• Treated water from the process can then be recirculated as wash water meaning the system runs as a closed loop.

​

• Sludge removed during the water treatment can then be further dewatered using a filter press, centrifuge or dewatering bag dependant upon customer requirements.
