Abstract Large quantities of dissolved organic carbon in prairie surface water reservoirs make sustainable treatment quite challenging. Organic material is a precursor for the formation of disinfection by-products. Here, ozonation and biological activated carbon filtration were used as methods for removing dissolved organic carbon from the water of a small prairie reservoir used as a drinking water source. Biofiltration alone yielded significant reductions in dissolved organic carbon, colour, total trihalomethanes and chlorine demand. When ozonation preceded biofiltration, the increased proportion of biodegradable dissolved organic carbon allowed for significantly greater (p<0.05

Various laboratory-scale process configurations were tested for the biological treatment of a combined wastewater stream of several chemical factories. The untreated wastewaters, rich in halogenated organics (1250±389 mg/l DOC), were also highly saline (32±11 g/liter TDS 550°C) and toxic (Microtox™ EC50 = 1.5±2.0%). Biphasic (anaerobic/aerobic) laboratory bench-scale reactor systems yielded reduction of dissolved organic carbon by 70 to 84%, in the absence and presence of powdered activated carbon, respectively. The anaerobic phase proved to be essential in all systems, both for dissolved organic carbon removal and for detoxification. Similar efficiencies were obtained in either activated sludge or aerated lagoon type reactors, but in the latter case, longer hydraulic retention times were required. DOC removal was found to decrease with increased salt concentration; however, a 50% efficiency was achieved even at 90 g/l TDS. Toxicity elimination as judged by the Microtox™ assay was highly variable in the absence of activated carbon but stable and efficient in its presence.
