Nitrification treatment of wastewater
Patent
·
OSTI ID:5310053
In a two stage activated sludge plant, where in the first stage the major proportion of the organic pollutants is decomposed and in the second stage the decomposition of the residual organic pollutants is conducted in conjunction with nitrification, the nitrifying bacteria are fixed on a low-density, macroporous carrier, e.g., particulate, polyurethane, optionally with activated carbon as well. The second stage can be operated as a mixed activated sludge tank or a biological filter, and in either case, it is possible to avoid a post clarification stage.
