The use of Industrial Internet of Things (IIoT) in ETPs can improve the efficiency and effectiveness of the treatment process. IIoT sensors and devices can be used to monitor various parameters of the wastewater, such as pH, temperature, and flow rate. This data can be used to optimize treatment processes and detect issues before they become serious. Additionally, IIoT can be used to remotely control and adjust the ETP, allowing for more efficient use of resources and faster response times to changes in wastewater conditions.
