Buffering capacity test
WebThe buffering capacity of an anaerobic digester is determined by the amount of alkalinity present in the system. The bicarbonate ion () is the main source of buffering capacity to maintain the system's pH in the range of 6.5–7.6. The concentration of in solution is related to the percent of carbon dioxide in the gas phase.
