Is manual measurement sufficient for pH management in drainage neutralization tanks? Utilizing continuous measurement and chemical dosing control.
Continuous monitoring of pH fluctuations that are difficult to grasp with manual measurements! Introducing methods for improving the efficiency of water quality management and chemical dosing control in wastewater neutralization tanks.
In the factory's wastewater neutralization tank, the pH is adjusted by injecting acidic and alkaline chemicals, but fluctuations in pH can occur due to changes in the manufacturing process or variations in incoming wastewater. Relying solely on periodic manual measurements makes it difficult to grasp the pH fluctuations that occur between measurements, which may delay responses to abnormalities. ■ Efficiency of Management through Continuous pH Measurement By continuously measuring pH, the condition of the wastewater can be monitored continuously, and it can also be utilized for alarms when set values are exceeded and for coordination with chemical injection equipment. Additionally, incorporating chemical injection control based on measurement values can reduce the burden of manual adjustment tasks and stabilize the neutralization process. However, appropriate control also depends on conditions such as mixing state and chemical injection position on the equipment side. One of the devices that can be used for continuous pH monitoring and chemical injection control in such wastewater neutralization tanks 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 and feel free to contact us.
