Abstract

The applicability of microfiltration for achieving simultaneous waste reduction and bacterial control was investigated. Microfiltration productivity and separation performance was determined with an α-alumina membrane of 0.5 μm pore-size and a commercial semi-synthetic microemulsion with and without model contaminants such as hydraulic oil and bacteria. Results indicate that it is possible to obtain excellent separation of extraneous emulsified tramp oil from native semi-synthetic emulsion while maintaining high productivity at low pressure. A 7-log reduction in bacteria is attained along with a 50-95 % reduction in indotoxin.
