Indretning til klaring af vand og fremgangsmåde til implementering

摘要

The invention concerns a water clarifying device comprising a flotation zone (c), a membrane-based filtering zone (e) and extracting means (d), the flotation zone (c) and the membrane-based filtering zone (e) having a common partition wall (P), the common partition wall (P) including in its lower part an opening (o) directly allowing through flotated water towards the filtering zone (e), thereby feeding the membranes with flotated water from down upwards both in filtering phase and in backwashing phase.
