How to monitor and control key parameters such as temperature, pH value, and alkalinity in the reactor?
Accurate monitoring and effective control of key parameters such as temperature, pH, and alkalinity within an anaerobic reactor are crucial for maintaining stable operation and efficient treatment during its operation. So, how can we achieve this goal? First, let's discuss temperature monitoring and control. Temperature significantly affects anaerobic reactions. Generally, the suitable temperature range for mesophilic anaerobic reactions is 30-38℃, while for thermophilic anaerobic reactions, it is around 50-55℃. To accurately monitor the temperature, multiple high-precision temperature sensors are usually installed at different locations within the reactor. These sensors can transmit temperature data to the control system in real time. There are two main methods for controlling temperature. One is to adjust the temperature inside the reactor using external heating or cooling devices, such as hot or cold water circulation systems. Another is to use the reactor's insulation layer to reduce heat loss or absorption and maintain temperature stability. Next is the monitoring and control of pH. The pH directly affects the activity and metabolic processes of microorganisms. The ideal pH for anaerobic reactions is usually between 6.8 and 7.2. To monitor the pH in real time, professional pH sensors will be used.
