Peat Filtration for Oil Removal

Document Type: Proceeding Paper

Part of: Environmental Engineering

Abstract:

An investigation was carried out to assess the potential of horticultural peat produced in Saskatchewan as a filter medium in treating five oil-in-water emulsions (standard mineral oil, Midale crude oil, cutting oil, refinery effluent and produced waters). Eight-hour column tests showed that oil removal efficiencies varied between 34 and 99 percent, depending upon the type of the emulsion and the flow rate. Column breakthrough studies were conducted for flow rates of 50 and 25 mL/min for Midale crude oil and refinery effluent respectively. The oil removal capacity of untreated peat was compared with two pretreated peats (wet-heated and oven-dried, wet-pyrolyzed at 150?C) and six other media (coal, sand, fiberglass, polypropylene, amberlite and activated carbon) using eight-hour column tests with a standard mineral oil-in-water emulsion. Study results are discussed.
