Sludge Blanket

The Krofta range of DAF clarifiers can be equipped with an automatic Sludge Blanket Controller (SBC). The controller allows automatic sludge blanket monitoring and adjusting of removal rates in order to maintain optimum blanket thickness. As the scoop speed is no longer an operator variable, it never runs too fast picking up excess water nor too slow producing excessive blanket thickness. This yields an increased average sludge consistency and overall improvement in clarified water quality.
