BioMix-DC Enhanced Anaerobic Mixing Systems optimize biological phosphorus removal by transforming a traditional anaerobic selector into an intensified fermentation tank by alternating a short mixing cycle with a long deep cycle. The system is designed to adapt to changing process conditions to optimize volatile fatty acid (VFA) formation and biological phosphorus removal. The deep cycle stratifies the reactor to increase anaerobic solids retention time (SRT), minimize oxidation-reduction potential (ORP), and maximize VFA formation. These conditions improve biological phosphorus removal.
- Enhances fermentation by optimizing VFA formation
- Boosts phosphorus accumulating organism (PAO) population to provide consistently low effluent phosphorus
- Provides energy savings of 90% or greater compared to continuous mechanical mixing
During the deep cycle, mixing is suspended for prolonged periods of time allowing for solids to accumulate, enhancing fermentation and VFA production. During the mixing cycle, intermittent mixing of tank contents is provided by bursts of compressed air fired through patented, engineered nozzles located at the floor of the tank. The cycle parameters may be adjusted to optimize mixing, power utilization, and VFA generation, manually or through automated process feedback. The operating regime of BioMix-DC is site dependent since each biological phosphorus removal treatment process operates differently based on the influent characteristics and facility design.
BioMix-DC provides energy savings of 90% or greater compared to continuous mechanical mixing in anaerobic zones. Compared to conventional mechanical mixing, 40-60% less active mixing energy is required when resuspending solids.
Process Optimization
BioMix-DC provides proven negligible oxygen transfer; the system is designed to drive down process ORP. Operators can adjust mixing frequency to optimize phosphorus removal and maximize VFA formation.
Unparalleled Flexibility
BioMix-DC easily integrates with other BioMix Compressed Gas Mixing Systems used in anoxic, swing, or post-anoxic zones. Cycling parameters are operator adjustable or controlled via instrumentation feedback. The technology is compatible with in-line mixed liquor fermentation, sidestream RAS fermentation, and sidestream mixed liquor fermentation.
Straightforward Operation
In a BioMix-DC system, zero mechanical or electrical components are in the wastewater. Only non-clogging, self-cleaning parts are in the tank. 100% redundancy is provided by the standby compressor.
