Abstract
The discharge of industrial wastewaters containing oily contaminants such as motor oils, greases, vegetable oil processing wastes, etc. , to the sewer is being regulated by increasingly tighter state and federal environmental standards. Microporous alumina membranes may be advantageously employed in these situations due to their superior chemical and/or temperature resistance properties. We have investigated the feasibility of utilizing Membralox alumina membranes for oil and grease removal from a typical industrial wastewater stream. Some performance data such as quality of permeate produced, permeate flux and water permeability with Membralox alumina membranes are presented. Separation characteristics of different microporous alumina membranes with a mean pore diameter from 40 to 2000 Angstrom are also discussed.
