Ultrafiltration Characteristics of Oil-Detergent Water Systems: Membrane Fouling Mechanisms.
Abstract
The ultrafiltration characteristics of processing oily bilge water, synthetic lubricating oil, and nonionic detergents with distilled river and seawater are evaluated with noncellulosic tubular membranes. Water flux behavior (membrane fouling) is dictated by membrane resistance increase due to detergent-membrane interaction and due to surface fouling in the presence of oil-detergent emulsion and suspended solids. Membrane fouling, as well as membrane cleaning requirements, are dependent on the type of oil/detergent/water system. Flux decline could be minimized by operating at temperatures above 35C and/or with short-term membrane depressurization. In all cases the steady state water flux is a function of initial membrane water flux. Depending on the water/detergent system, water flux of 15-103 gal/sq ft/day at 25C and pressures less than 25 psi can be obtained. (Author)
