ABSTRACT:
A coating modification process is provided for use in ultrafiltration systems to improve the adherence of porous coatings of preformed, aggregated, inorganic metal oxide particles, to substrates, particularly those comprised of hollow tubular porous carbon members. The process involves exposure of the coated members, during the initial treatment to water vapor at specific humidity, temperature and times. The ultrafiltration systems so treated are particularly well-suited for prolonged use in the concentration and separation of oil from mixtures of oil, water and detergents, the recovery of polyvinylalcohol from textile wastes, and other useful applications.
