Bar Screens

WTP Equipment Corp. front-cleaned Mechanical Bar Screens - for cost-effective, automatic collection and removal ofwastewater screenings. Screen size, bar rack opening size, discharge height and channel dimensions are engineered to your specific application.

FULL DEPTH BAR RACK CLEANING is achieved on each pass of the rack as the front face and inside surfaces of the parallel rectangular screening bars are cleaned over the full bar rack slot depth. This ensures complete screenings removal and prevents screen blinding by materials lodged between bars and, since the bar rack height is greater than the design maximum water depth, the flow cannot submerge and overload the screen.

CLEAN, POSITIVE SCREENINGS DISCHARGE for efficient operation is achieved as an additional advantage of using parallel screening bars. As screenings are lifted to discharge the traveling rake makes a smooth transition above the bar rack onto a flat deadplate to prevent the raised screenings from dropping behind the bars and to eliminate liquid from dripping onto the operating floor area. This, with the clean deposit of screenings into the discharge chute resulting from rake rear swing-out behind the deadplate, achieves maximum screening efficiency.
