Abstract
The present invention describes a method of optimizing COconcentration to increase the specific growth rate of Anammox bacteria and methanogens in wastewater and sludge treatment, as well as novel systems and methods of treating wastewater and sludge. The specific growth rate or doubling time of the Anammox bacteria and methanogens were determined to be sensitive to dissolved COconcentration. Optimizing dissolved COconcentration increases the specific growth rate of the Anammox bacteria, which may be used as an alternative biological nitrogen removal process for the treatment of domestic wastewater. In the method and system of treating sludge, the COstripper returns biogas with low COconcentration to the headspace of an anaerobic digester in order to lower the headspace COconcentration and therefore, the soluble COconcentration. The lower soluble COconcentration increases the specific growth rate of the methanogens for a more efficient anaerobic digestion process.
