  • Simulation of sludge dewatering on belt filters

    A mathematical model for belt filters was developed to determine optimum load rate and belt speed during drainage of flocculated biological sludge. Numerical simulations were performed for belt filters with and without plows, and the model fit experimental data well. Experiments showed that highly compressible cakes were formed during drainage, which was important. Due to cake compression, the ...

  • Size reduction of filter cakes with the Gericke Nibbler

    Application: Separating solids from a suspension by filtering, centrifuging or drying. Then shredding of the filter cake. Process: The suspension is pumped into the press. The solid particles are deposited on the filter medium and form filter cakes on the filter plates. To press as much liquid as possible out of the filter cake, the plates are compressed at high pressure by a hydraulic press. ...

  • Rotary drum vacuum filters for production of wallboard-grade gypsum

    ABSTRACT Conventional wisdom is that production of wallboard-grade FGD gypsum requires the use of horizontal belt vacuum filters for dewatering service, to limit cake moisture to 10% or less. New Brunswick Power initially planned to use HBVFs for gypsum dewatering for the FGD retrofit to its 3 x 350 MW Coleson Cove plant. However, project budget constraints led to cost reduction ...

  • Rotating belt sieves for primary treatment, chemically enhanced primary treatment and secondary solids separation

    Fine mesh rotating belt sieves (RBS) offer a very compact solution for removal of particles from wastewater. This paper shows examples from pilot-scale testing of primary treatment, chemically enhanced primary treatment (CEPT) and secondary solids separation of biofilm solids from moving bed biofilm reactors (MBBRs). Primary treatment using a 350 microns belt showed more than 40% removal of ...

  • A New, Real Technology for Solids Dewatering

    Over the past decade, there have been few significant improvements to the performance in sludge dewatering technologies. Most improvements, other than process optimizations from the polymer industry, have been minor adaptations to the various dewatering technologies such as adding additional pressure rollers or modifying the diameters of pressure rollers on a belt filter press. The adoption of ...

  • OEM Wear Strip solution - Case Study

    The Client Challenge Wear strips were needed for a sliding filter belt. In this particular application, a vacuum is applied from the underside of the assembly, through the filter belt and also through the slide wear strip, pulling the filtered material through the filter belt as it conveys down the wear strips. Multiple wear strips are joined to each other, end on end, to reach lengths of ...
