A Treatment Process for Nitrification/Denitrification
The BioCycle system operates in conjunction with fine bubble diffusers to cause the reactor to alternate between aerobic and anoxic treatment conditions. Due to the insignificant amount of gas transferred to the wastewater, the BioCycle system may easily be optimized for biological phosphorus release, denitrification, and alkalinity recovery. Normal aeration of the tank is accomplished using the existing facility blowers feeding fine bubble diffusers. After the aeration phase is completed using the diffuser system, BioCycle will actuate a valve to stop air to the diffusers and start the BioMix system to provide mixing during the anoxic phase. Upon completion of the anoxic phase, BioCycle will actuate the valve to admit air to diffusers and aeration will begin again. The sequencing of the aerobic - anoxic phasing may be determined either by using a proprietary control algorithm to detect oxidation-reduction potential (ORP), and using that value as the trigger for sequencing, or by setting a pre-determined time duration for each phase.
