“…Beder and Gillespie (1970) demonstrated color removal from the bleach-plant effluent with ultrafiltration film membranes, and extensive tests were carried out at the Champion International plant at Canton, North Carolina (Fremont, Tate, and Goldsmith 1973). Dynamic hyperfiltration and ultrafiltration membranes have been studied by Perona et al (1967), Csurny et al (1967), Johnson, Minturn, and Moore (1974),and Minturn (1974). Dynamic membranes and more recently developed conventional membranes have the advantage of allowing operation at the elevated temperatures of these process streams in the plant.…”
