  • 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 ...

  • 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 ...
