Title (EN) SUBMERGED MEMBRANE FILTRATION SYSTEM USING RECIPROCATING MEMBRANE
(FR) SYSTÈME DE FILTRATION SUR MEMBRANE IMMERGÉE UTILISANT UNE MEMBRANE À MOUVEMENT ALTERNATIF

Abstract:
(EN) The present invention relates to a membrane filtration system comprising a mechanical membrane reciprocation system for reducing or eliminating membrane fouling. The described membrane filtration system can be operated with a higher flux and lower fouling, compared with membrane filtration systems using air scouring. In addition, the system can remove nitrogen and phosphorous using a single RAS and a single inner recirculation line, or without the inner recirculation line. Various mechanical means may also be employed to generate a reciprocating motion.
(FR) La présente invention concerne un système de filtration sur membrane comprenant un système de membrane mécanique à mouvement alternatif destiné à réduire ou éliminer l'encrassement de la membrane. Le système de filtration sur membrane décrit peut fonctionner avec un flux plus élevé et un encrassement réduit, comparé à des systèmes de filtration sur membrane utilisant le décapage à l'air. En outre, le système peut éliminer l'azote et le phosphore à l'aide d'un seul RAS et d'une seule ligne de recyclage interne, ou sans ligne de recyclage interne. Divers moyens mécaniques peuvent également être utilisés pour générer un mouvement alternatif.
(KO) 본 발명은 막 오염을 감소시키거나 또는 제거하기 위한 기계적 막 왕복 시스템을 포함하는 막 여과 시스템에 관한 것이다. 기술된 막 여과 시스템은 공기 정련을 사용하는 막 여과 시스템들에 비해 더 높은 플럭스 및 더 낮은 오염으로 운전될 수 있다. 게다가 시스템은 하나의 RAS 및 하나 내부 재순환 라인으로 또는 내부 재순환 라인 없이 질소 및 인을 제거할 수 있다. 왕복 운동을 생성하기 위하여 여러 기계적 수단들이 또한 채용될 수 있다.
