The objective of this research was to determine the applicability of high rate or pressure filtration to the treatment of solids-stabilized, oil-in-water emulsions. Performance was evaluated by suspended solids removal, oil removal and headloss for various filtration conditions. Separation of the oil and water phases was the overall goal of the filtration process. This might be accomplished by removing the stabilizing solids near the top of the filter bed and then providing adequate bed depth for the coalescence and removal of the oil droplets or by the addition of chemical filter aids to promote the coagulation and filtration of the solid-oil emulsion particles. The determination of removal mechanisms and kinetics was not an objective of this thesis. Headloss profiles were obtained to locate depth of clogging within the filter. Sampling of the waste stream was limited to the influent and effluent samples.
