ANAEROBIC DIGESTION PROCESS MONITORING DEVICE AND METHOD THEREOF

摘要

Disclosed herein are a device and a method for extracting individual organic acids, Total Volatile Fatty Acids (VFA), ammonium (NH4 +), buffering inorganic carbon compounds or hydrogen carbonate (HCO3 -) to determine their concentrations and the trends of said concentrations in an active anaerobic digestion (AD) process. The determination of said concentrations in real-time allows the AD operator to run the AD at optimal efficiency and ensure that the VFA and NH4 + concentrations do not reach toxic levels. A ratio of the concentration of total organic acids to the total inorganic carbon can be used to determine the performance of the digester.
