HydroScum-FLAP sludge extractors are attached to the side wall of the permanent reservoir tank. They consist of a square drainage gutter equipped with an automatically adjustable switch guard. A measuring sensor records the water level status with emerging sludge levels and draws the floating sludge by lowering the overflow edge. The HydroMatic control of the floating sludge extraction allows for different operating modes. The floating sludge is automatically recognised via an optical device and this enables the fully automated extraction.
The HydroScum-FLAP and HydroScum-FLOAT/P are HST-WKS licensed products.
