  • 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 ...

  • 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 ...

  • Dewatering of Industrial Sludge - Case Study

    At Ten Cate Protect, town of Nijverdal, The Netherlands, 2006 During the wastewater treatment process at Ten Cate Protect large quantities of sewage sludge are liberated. A couple of days per week this sludge is transported in tanker trucks to a waste disposal plant. On June 14th 2005 a Geotube MDS unit was put in operation at Ten Cate Protect to separate and condense the sludge of the aerobic ...

  • Geotube Dewatering for Lagoon Sludge - Case Study

    Background In many animal waste management schemes it is desirable to separate solids from waste water and/or manures. In cooperation with the Department of Animal and Dairy Science, animal waste specialists from Biological and Agricultural Engineering are field testing a technology new to agriculture, to remove solids from lagoons. The test is currently being conducted at the UGA Dairy ...

  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • Dewatering of moist sediments and soils for application to RaPID Prep AND RaPID assays procedures

    BACKGROUND INFORMATION: High moisture content (>30% by weight) can significantly lower concentrations of analytes detected in the RaPID Prep soil methods. In these methods, water associated with a sample will increase the volume of the extraction solution (liquid phase) and decrease the amount of soil (solid phase) in a weighed sample. In some cases, water may also decrease the ...
