Abstract

Przedmiotem zgłoszenia jest urządzenie filtrujące (100), które zawiera, w zbiorniku filtracyjnym (106) lub podobnym, warstwę materiału filtrującego (110) i filtruje doprowadzoną zanieczyszczoną wodę poprzez przepuszczanie jej przez warstwę materiału filtrującego (110). Urządzenie filtrujące zawiera urządzenie płuczące (200) materiał filtrujący, które zawiera: spiralną śrubę (204) umieszczoną pionowo w warstwie materiału filtrującego (110); oraz jednostkę napędową (206, 208) śruby, która obraca śrubę (204) wokół osi śruby. Urządzenie filtrujące ściska i płucze materiał filtrujący (110) poprzez obracanie śruby (204). Urządzenie płuczące (200) materiał filtrujący, które nie zawiera cylindra zewnętrznego otaczającego śrubę (204), transportuje materiał filtrujący (110) w górę, w stanie, w którym zewnętrzna krawędź obwodowa śruby (204) pozostaje w bezpośrednim zetknięciu z warstwą materiału filtrującego.
