Abstract (en)

[origin: EP1046751A2] A sewage screening apparatus (10) comprising a screen arrangement having a continuous belt screen (11) for capturing screenings contained within the sewage flow (16) to enable their subsequent removal therefrom, the screen arrangement having a head space (20) above the level of the sewage flow when in use. The apparatus further comprises a washing apparatus (43), housed within the head space (20) of the screen arrangement, into which screenings captured by the screen arrangement and an aqueous liquid are introduced. The washing apparatus (43) includes impeller means (48,) for generating turbulence within the aqueous liquid to effect washing of the screenings prior to their removal from the sewage screening apparatus (10). <IMAGE>
