Biodegradation occurs under different redox conditions (aer-obic, anoxic, and anaerobic), with each condition offering biodegradation pathways that may not be available in others dueto its distinct microbial consortia. Aerobic treatment generallyresults to high biodegradation of TrOC through the action of het-erotrophic bacteria and autotrophic ammonia-oxidizing organisms(AOOs) in the form of bacteria and archaea
