AUTOMATED BICARBONATE TESTING OF DIGESTER SLUDGE

Monitoring bicarbonate levels is an excellent way to assess the health of the biological system. Sufficient bicarbonate in the sludge leads to a stable process, while falling concentrations mean the biological system is at risk.

Graph comparing bicarbonate and volatile fatty acids (VFA) concentrations over six months. Bicarbonate is represented by a black line and VFA by a red line. Y-axis shows concentration in g/L, X-axis shows time from January to June. Annotations explai

Graph comparing VFA and bicarbonate levels against pH. pH line decreases with increased VFA, bicarbonate slopes down linearly. Text: 'If bicarbonate buffer is consumed by acids completely, pH drops below 6 and the biogas process collapses.'"

» Allows operators to respond before changes in pH happen.

» Increases feeding flexibility by giving operators the information they need.
