WASTE WATER RECOVERY

摘要

A wet waste treatment facility for recovering water and solids from wet waste has a coarse filter for filtering received wet waste and thereby retaining a retentate while allowing coarse-filtered fluid to pass through. Water cleaning means comprising at least one sedimentation chamber cleans coarse-filtered fluid to thereby produce cleaned water at an outlet. The coarse filter separates a large proportion of the solids from the wet waste, for recovery. The water cleaning means removes a large proportion of remaining solids from the fluid waste, enabling separation and recovery of cleaned water and solids in a manner which utilises the coarse filter and water cleaning means most efficiently. The frequency with which the water cleaning means has to be emptied is thereby reduced. The water cleaning means may have an oil and detergent-removing filter. A loading ramp adjacent to the coarse filter may receive wet waste directly from large vehicles such as gully trucks and road sweepers. A mobile treatment facility is also disclosed. Waste washing and sorting apparatus may use cleaned water retrieved from the waste which is washed and sorted. Thus, varying grades of cleaned solid waste may be provided for re-use using reclaimed water and without the requirement for transportation to a separate solid waste processing facility. The treatment facility may receive rain water run off and run off from vehicle cleaning operations. Vehicle cleaning operations may utilise water cleaned by the treatment facility, thereby significantly reducing the water consumption requirements for vehicle cleaning.
