Aerobic Treatment Systems Aerobic treatment processes convert the biodegradable organic content of wastewater streams (BOD5 or COD) into Carbon Dioxide (CO2) and new cell mass (sludge). Aerobic systems are net energy users and produce approximately ten (10) times more waste sludge than anaerobic systems for the same application. However, aerobic systems can treat wastewater streams to lower organic and Total Suspended solids (TSS) concentrations and are typically required for final discharge (SPDES or NPDES) permits.
EMG typically recommends the Anaerobic Fluidized Bed Digester (AFBD) system to its clients, due to superior anaerobic technology efficiency and reliability, lower operating cost, and significantly lower sludge production. However, we provide turnkey services for aerobic processes as a complementary polishing treatment step. Aerobic processes can facilitate compliance with strict final discharge (SPDES or NPDES) permit limits for BOD5, TSS, Nitrogen (N) and Phosphorous (P).
Aerobic, anoxic, and other polishing systems that EMG offers include:
Conventional Activated Sludge (AS) Systems
Extended Aeration Systems
Sequencing Batch Reactor (SBR) Systems
Aerobic Fluidized Bed Reactor (FBR) Systems
Nitrification and De-nitrification (N-Removal and Reclamation) Systems
Phosphorous Removal (P-Removal and Reclamation) Systems
