Gully and Road Sweeper Waste Treatment and Recycling
Road sweeping residues and gully waste from drainage operations contain predominantly water and silt but also stones, sand, organics, and rubbish. By processing and classifying the fractions within the waste, we can determine what is suitable for recovery to be used as a secondary aggregate.
Here at BKP, we have a brand new gully and road sweeper recycling plant system designed to recover and recycle aggregate from up to 100 tonnes of the waste per day. The process uses water-based washing techniques to separate recoverable and recyclable aggregates from leaves and other waste picked up by the sweeper or Gully Tanker. When coupled with a water treatment system and sludge dewatering plant, the system is capable of operating as a closed loop washing system requiring little additional water and therefore saving on expensive utility costs. The unit also has an integrated hydraulic density separator to further process the oversize fraction of the waste.
How does it work?
• On arrival at the BKP Treatment plant, the vehicle would reverse and discharge its contents into a wedge pit type arrangement do remove excess water, from where it is loaded into the WT-250 recycling plant using a telehandler type machine.
• The material in the V shaped hopper is conveyed using a horizontal auger to the 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 transferred to the hydraulic density separator section where its further separated into a float and sinks fraction.
• The fine solids laden water from the unit is first passed over the dewatering screen (to remove any minus 10mm to 1mm organic products) before being forwarded to the BKP 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 our centrifuge.
BKP has a fleet of vehicles designed to transport bulk liquids and other hazardous materials to provide collection services alongside the treatment of your waste.
