How can we make the water of Jialing River safe to drink?

"By treating water from the Jialing River, this water plant guarantees 80% of the tap water supply for the entire county, ensuring that about 200,000 people have access to safe and reliable drinking water."

In a recent interview, Lan Gong, a senior engineer of Meacon Southwest Region, said, “When we heard the above information from our customers, we deeply felt the responsibility and mission we shouldered.

Zhongliangzi Water Plant, as a part of the dual water source water supply system in Cangxi County, Guangyuan City, Sichuan Province, is of great importance in improving the quality and stability of local water supply. The first phase of the water plant project has an investment of 150 million yuan and a daily water output of 50,000 tons.

Lan Gong introduced that with the help of Meacon process automation solutions, the water plant not only improved production efficiency and the accuracy of water quality control, but also greatly improved response speed, achieving seamless monitoring of the entire chain from water source extraction, treatment to transportation.

Geographical location of Zhongliangzi Water Plant

During the project cooperation, Meacon customized process automation solutions for the water plant, including dozens of automation instruments such as ultrasonic level meters, turbidity meters, pH meters, residual chlorine analyzers, pressure sensors, etc., covering every key link from raw water treatment to terminal water supply, ensuring the real-time and accuracy of water quality monitoring.

When talking about the application of automated instruments in water treatment processes, Lan Gong shared that ultrasonic level meters can be installed in large containers such as clear water tanks, sedimentation tanks, and regulating tanks for non-contact measurement of liquid level heights; turbidity meters are usually installed in the pretreatment stage to measure the content of suspended particles in the water; pH meters are indispensable in the entire water treatment process, especially in steps such as coagulation, disinfection, and softening; and residual chlorine analyzers are mainly installed in the post-disinfection stage to monitor the residual chlorine content in the water.

Pressure monitoring is essential to ensure the normal operation of equipment, prevent pipe bursts or leaks, and optimize energy management of pump stations. In high-pressure filtration processes such as reverse osmosis, it is a key parameter that is directly related to the service life and treatment efficiency of the membrane. Therefore, pressure sensors are widely used in pump stations, filtration systems, pipelines, etc. to monitor pressure changes in various links of water treatment.

These process automation instruments have built a solid water quality safety line for the water plant, so that every drop of water can flow safely and clearly into thousands of households after being processed and purified layer by layer. "Lan Gong said, we also look forward to working with more partners to make water treatment safer, more efficient and sustainable.
