Sludge inoculum

Biological. Bridid et al. (1979) reported BOD and COD values of 0.02 and 2.49 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d. The ThOD for tert-butyl alcohol is 2.59 g/g. In activated sludge inoculum, 98.5% COD removal was achieved. The average rate of biodegradation was 30.0 mg COD/g-h (Pitter, 1976). 

In activated sludge inoculum, 98.0% COD removal was achieved. The average rate of biodegradation was 16.7 mg COD/g-h (Fitter, 1976). 

Biological. Under anaerobic and aerobic conditions using a sewage inoculum, 1,3-dinitrobenzene degraded to nitroaniline (Hallas and Alexander, 1983). In activated sludge inoculum, following a 20-d adaptation period, no degradation was observed (Fitter, 1976). 

Biological. When 2,4-dinitrophenol was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, significant biodegradation with rapid adaptation was observed. At concentrations of 5 and 10 mg/L, 60 and 68% biodegradation, respectively, were observed after 7 d (Tabak et al, 1981). In activated sludge inoculum, 85.0% COD removal was achieved. The average rate of biodegradation was 6.0 mg COD/g-h (Fitter, 1976). 

In activated sludge inoculum, following a 20-d adaptation period, no degradation was observed (Pitter, 1976). 

Biodegradation average rate of biodegradation 71.0 mg COD g- h- based on measurements of COD decrease using activated sludge inoculum with 20-d of adaptation to the substrate (Pitter 1976 quoted. Scow 1982). Biotransformation ... 

Biodegradation average rate of biodegradation 30.0 mg COD g h based on measurements of COD decrease using activated sludge inoculum with 20-d of adaptation to the substrate (Fitter 1976 quoted. Scow 1982) V,(aq. aerobic) = 677 320 h, based on river die-away studies V/aq. anaerobic) = 2400-12000 h, based on degradation rates in microcosm studies simulating anaerobic aquifers (Howard et al. 1991). ti/j(aerobic) = 28 d, t,//anaerobic) = 100 d in natural waters (Capel Larson 1995)... 

Biodegradation > 90% degradation in 3 d using an activated sludge inoculum in 24 h in batch aeration in sewage and 14 d using sediment from the Rhine river as inocula (Howard 1990).
