The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid. WebGravity belt thickeners have an open equipment design and can be difficult to capture odorous emissions for treatment. Consequently, the whole area requires odor control. The belt has to be washed periodically to avoid blinding. Gravity belt thickeners are available with many manufacturers. j patrick farrell waukesha
