PureBoxTM CMBR Wastewater Treatment Systems

RODI's containerized membrane bioreactor treatment system (CMBR) is designed to 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.
