New Heavy Duty Screen Installation for Hunter Water to Solve Noxious Weed Problem

The control of weed infestations has been an ongoing problem for Australia`s Hunter Water at the intake to their Balickera Canal Pump Station.
Continuous regulated treatment of the weeds with herbicides has been carried out as part of Hunter Water`s Noxious Weeds Management Plan, but
removal of the weeds from the water flow posed a health and safety problem as the existing screens needed to be cleaned manually.
The EVA Back-Raked screens proposed by EPCO (Australia) provide an effective and proven solution to this problem. The EVA Back-Raked
screens are heavy duty screens especially suited to river water intakes where weeds, leaves, logs, branches and other debris need to be removed.
The operation of these screens is simple. The tines plunge into the debris mass at the base of the intake channel and lift the mass upwards cleaning the entire bar screen in one ascending movement. From there the debris is discharged to a conveyor or bin.
The first of its kind in Australia, this installation will begin later in 2008. The EVA Back-Racked screens can also be used for power and desalination projects, sewage treatment plant inlet works, storm over-flow sites, or for industrial complexes where effluents have to be treated prior to discharge.
