Combined organic carbon and complete nitrogen removal using anaerobic and aerobic upflow filters

, : Combined organic carbon and complete nitrogen removal using anaerobic and aerobic upflow filters. Water Science and Technology 30(12): 297-306

Upflow aerobic and anaerobic filters were used to study the effects of aeration rate on the nitrification of anaerobically pretreated effluents and of recycle-to-influent ratios on methane production rate and nitrification/denitrification in a combined aerobic/anaerobic treatment process. The amount of NH3-N to be nitrified depended on the amount of organic matter remaining in the pretreated effluent.
