Abstract

The treatment of phenolic compounds from coal gasification plants using ultrafiltration and hyperfiltration is presented. Dynamically formed hydrous zirconium (IV) oxide membranes on several types of supports were the focus of the investigation. The pH variations of 6.5 to 11, pressure variations of 1 724 to 6 895 kPa (250 to 1 000 psig), and concentration variations of 1 to 400 mg/l were examined. Phenol reductions greater than 95% were obtained with several membranes, and flux rates were greater than 4.08 ${\rm m}^{3}/{\rm m}^{2}\cdot {\rm d}$ (100 gal/day/sq ft).
