Simultaneous Nitrification Denitrification in an Aerobic Mbr Treating High Strength Pet Food Wastewater

This paper discusses nitrogen removal mechanisms in an aerobic membrane bioreactor (MBR) treating high strength pet food wastewater characterized by oil & grease, COD, BOD5, TSS, TKN, NH4-N concentrations of 2800 mg/L, 25000 mg/L, 10000 mg/L, 4500 mg/L, 1650 mg/L and 1300 mg/L respectively. An MBR operating at SRT >25 days achieved mixed liquor total suspended solids (MLTSS) concentrations >300...

Nitrification and denitrification gene abundances in swine wastewater anaerobic lagoons.

Although anaerobic lagoons are used globally for livestock waste treatment, their detailed microbial cycling ofN is only beginning to become understood. Within this cycling, nitrification can be performed by organisms that produce the enzyme ammonia monooxygenase. For denitrification, the reduction of nitrite to nitric oxide can be catalyzed by two forms of nitrite reductases, and N,O can be re...

Denitrification Enzyme Activity in Swine Wastewater Effluent of a Nitrification/denitrification Treatment System

Intensification of swine production in the U.S. and around the world requires advanced manure management. For swine manure management in the state of North Carolina, one system met all of the required advanced management criteria, and it was qualified as an environmentally superior technology. This investigation was part of the testing for this superior technology. The objectives of this invest...
