This paper describes the principle and the technical details of a cheap titrimetric sensor for the measurements of total and partial alkalinity and the estimation of bicarbonate and volatile fatty acids concentrations in anaerobic digestion processes. The on-line operation of the sensor connected to a 1 m upflow fixed bed reactor treating raw industrial wine vinasses has been shown to be reliable over a five year period of daily use with one measurement every half hour. In addition, this sensor… CONTINUE READING
