TURBINE FOR A COMMUNITY SEWER SYSTEM AND METHOD FOR CLEANING THE ROTOR THEREOF

摘要

A turbine for integration into a community sewer system for channelling wastewater from a building or group of buildings, comprising a turbine housing (10) and a rotor provided with an axle (25) and a number of blades (20). The housing comprises a substantially cylindrical part (11), the axis of which is substantially parallel to the rotor axle (25). The blades (20) comprise a cut-out (22) at their distal end.In a method for cleaning a turbine of this type, a pressure switch maintains a pair of electro valves closed as long as the detected upstream pressure (clean water supply line) is less than or equal to the downstream pressure (inside the turbine).
