RODI's containerized membrane bioreactor treatment system (CMBR) is designed treat domestic or industrial wastewater for BOD removal. This system was designed in multiple sizes to fit a 20 ft or 40 ft shipping container (including bioreactor) and provides a production rate of 5,000 to 50,000 gallons per day.
RODI Systems’ CMBR process uses aerobic digestion as does a conventional system. However, with the CMBR process, a pressurized membrane module is used to separate the treated wastewater from the biomass in the bioreactor. Use of the membrane offers several advantages:
Smaller Bioreactor - Membrane separation of liquid and solids allows the biomass in the bioreactor to be as high as 25 grams per liter. This results in a bioreactor a fraction of the size as that necessary in a conventional system of the same throughput.
Longer Sludge Retention - Longer sludge retention times in a membrane bioreactor mean easier sludge handling and less sludge to be disposed of. Membrane bioreactors are less sensitive to changes in wastewater quality.
Superior Effluent Quality - Since the treated wastewater passes through a membrane, the quality of the effluent is superior and virtually devoid of any suspended solids. Effluent from a membrane bioreactor may be fed directly to a reverse osmosis unit with no additional treatment.
