Abstract
A centrifuge apparatus and a method of filtration are described. The centrifuge has radial and lateral filtration surfaces and separate discharge chambers for each. The lateral filter is located at an imperforate radial distance from the radial filter. This distance forces the filtration to occur through the radial filter and develop the filter cake rather than pass through the lateral filter which has no developed cake. The use of separate, laterally-disposed withdrawal chambers at different radial heights allows accurate control over the hydraulic filtration forces acting across the filter surfaces.
