  • Krofta® Technologies specializes in liquid solid separation technology and manufactures a full range of flotation clarification and filtration equipment.

    Krofta is dedicated to technical innovations and has developed a sludge blanket controller (SBC) to allow for automatic operation of the Krofta Dissolved Air Flotation clarification equipment. The SBC will control the sludge blanket thickness for both the Multifloat (rectangular) and Supracell (circular) DAFs.

    SBC SLUDGE BLANKET CONTROLLER DESCRIPTION

    The controller allows automatic sludge blanket monitoring and adjustment of removal rates in order to maintain optimum blanket thickness. As the scoop/ scraper 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. Additional benefits include greater dewatering efficiency and a reduced dewatering capacity requirement.
