Is the pH management of the circulating liquid in the wet scrubber sufficient? Improvement through continuous measurement.

How to manage the pH fluctuations of circulating liquids caused by exhaust gas load and chemical injection? We will introduce the efficiency of state monitoring through continuous measurement and chemical injection control.

In the operation of wet scrubbers, do you ever feel challenges with fluctuations in the pH of the circulating liquid or adjustments to the amount of neutralizing agent injected? Especially in equipment that treats acidic gases with alkaline cleaning solutions, the pH of the circulating liquid can change due to variations in exhaust gas load and consumption of the neutralizing agent. It is important to continuously monitor the state of the circulating liquid, as deviations from the appropriate management range of pH may affect the absorption of the target components. ■ Improving management efficiency through continuous pH measurement of circulating liquid By continuously measuring pH, it becomes easier to understand changes in the circulating liquid due to exhaust gas load and chemical injection. Furthermore, through alarms based on set values and integration with chemical injection equipment, it can lead to reduced burden during abnormal situations and manual verification and adjustment tasks. One of the devices that can be used for monitoring and controlling the pH of the circulating liquid is the water quality monitoring controller "HI 520." 【Features】 ■ Modbus/RS485 compatible ■ 4-20mA analog output ■ Up to 5 relay contacts ■ Can connect 2 sensors to one main unit *For more details, please download the PDF or feel free to contact us.
