The aim of this study was to define denitrification kinetics using bacteria Paracoccus denitrificans cultivated in membrane bioreactor equipped with microfilter module with ceramic cartridge with cut off 0,45 mm. Water used in experiments was loaded with very strong nitrate concentration reaching up to 6,0 g NO3-/L. Methanol was used as carbon source and was added in an amount 30 % higher than the...
Microbiological denitrification has some disadvantages, including 1) decrease of fermentation activity of bacteria at low temperature, 2) serious risk of water contamination, and 3) production of nitrites. For these reasons, a new method for nitrate removal is required. A promising method seems to be two step process coupling nitrate adsorption on ion exchange resins followed by microbiological denitrification...
