ProTechtorâ„¢ Multi-Rake Bar Screen

The Kusters Water Multi-Rake Bar Screen was developed to solve the most demanding problems associated with wastewater pre-treatment. Kusters Water improved the basic design of conventional bar screens to offer a unique product to meet the ever increasing process needs of end users. The Kusters Water Multi-Rake Bar Screen combines fine or coarse screening with high solids capture rates, robust construction, long life, and low O&M costs all in one screen. This combination ensures operation when you need it most.

Functional Principle
Wastewater flows through the tapered stainless steel bars while the non-biological solids, such as paper and plastics, are trapped on the screen face. The screenings are removed from the tapered bars by rake arms fixed between two heavy duty roller chains. These rake arms utilize laser cut teeth that precisely engage and clean the tapered bars to a depth of 10 mm. The screenings are conveyed from the bars over a dead plate, where they have sufficient time to drain, and are discharged at the top of the screen into a dumpster, conveyor or compactor. The Multi-Rake Bar Screen is designed to tightly seal to the walls of the channel to prevent any bypass from occurring and, due to the design of the lower frame, a recess in the floor of the channel is not required.
