Method and system for treating wastewater and sludges by optimizing sCO2 for anaerobic autotrophic microbes

The present invention describes a method of optimizing CO2 concentration 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.
