Intelligent Online Water Quality Monitoring Network
Application background

Adding disinfectant to drinking water is a crucial measure to ensure the safety of drinking water. Its primary purpose is to kill or inhibit pathogenic microorganisms, such as bacteria, viruses, and parasites, in the water. Disinfectants will pass through an extended pipe network from the drinking water plant to the residential water end. Therefore, monitoring the presence of free chlorine at the end of the pipe network can help determine whether the disinfectant is ineffective and whether the terminal water poses a risk of causing disease.
Points are arranged between key nodes, including tributaries and main streams of the sewage network, to monitor the dynamics of upstream and downstream sewage in real time. The traditional manual sampling method cannot achieve one-hour interval monitoring, and because the points are all underground sewage networks, some points are in the middle of the road. Conventional online monitoring equipment faces problems such as a large footprint and difficulty in electricity use. Our sensor is compact and can be submerged in the monitoring well without requiring additional land space; it has low power consumption and can be powered by batteries. The data acquisition instrument is synchronously positioned in the monitoring well to address the issue of electricity consumption.
