This paper compares municipal wastewater (MWW) as a carbon source with other volatile fatty acids (VFAs) such as acetic acid, propionic acid and butyric acid in biological nutrient removal (BNR) processes. Biomass specific denitrification rates (SDNR) using acetic acid, butyric acid, propionic acid, MWW and primary effluent from batch studies were 107.2, 77.1, 37.9, 31.1 and 30.0 mg NO 3 –N/g...
The present investigation aims at estimating the biodegradation coefficients of surfactants. The biodegradabilities of Triton X-100 and Rhamnolipid were tested under aerobic, nitrate reducing, sulphate reducing and anaerobic conditions using a respirometer. The results indicated that in terms of biodegradability, Rhamnolipid is superior to Triton X-100, since it is biodegradable under all conditions,...
