AEROBIC AND ANAEROBIC TREATMENT OF C.I. DISPERSE BLUE 79 - VOLUM... 1 Citation AEROBIC AND ANAEROBIC TREATMENT OF C.I. DISPERSE BLUE 79 - VOLUM... Recent Science Inventory records from the EPA Tue, 11/25/2008 - 08:28 This study was conducted to determine the fate of C.I. Disperse Blue 79, one of the largest production volume dyes, and select biodegradation products in a conventionally operated activated sludge process and an anaerobic sludge digestion system. To achieve this objective, a pilot study was conducted from November 1987 to February 1989. The equipment operat, technorati.com

BIOLOGICALLY ENHANCED OXYGEN TRANSFER IN THE ACTIVATED SLUDGE PR... 1 Citation Biologically enhanced oxgyen transfer has been a hypothesis to explain observed oxygen transfer rates in activated sludge systems that were well above that predicted from aerator clean-water testing. The enhanced oxygen transfer rates were based on tests using BOD bottle oxygen uptake rates (OURs) on samples removed from the activated sludge system. Bench- and full-scale plant studies were performed to compare results of in situ OUR measurement techniques to BOD bottle OUR measurements. read, technorati.com
