Abstract

Способ очистки сырой загрязненной воды, включающий обеспечение корпуса (21), содержащего сепараторный элемент. Сепараторный элемент включает мембрану, которая не пропускает поток загрязняющих веществ и пропускает поток воды таким образом, что сырая вода, проходящая мембрану, проходит сквозь мембрану, очищаясь от загрязняющих веществ. Загрязняющие вещества извлекаются в накопительной камере (31), образуя возвратный поток (41), по меньшей мере часть которого возвращается в корпус и повторно проходит через сепараторный элемент. В одном варианте осуществления изобретения в воду перед ее поступлением в накопительную камеру нагнетают газ.Международная заявка была опубликована вместе с отчетом о международном поиске.
