  • Online Residual Chlorine Water Quality Automatic Sensor: The "Safety Sentinel" for Secondary Water Supply, Preventing Bacterial Pollution in Water Tanks!

    Time:December 1, 2025


    In the high - rise buildings of cities, secondary water supply tanks (pools) are important facilities to ensure the water supply for high - rise residents. However, they are like "time bombs" hiding risks. Since the water in the tanks stays for a long time and the cleaning and disinfection are not carried out in a timely manner, bacteria can easily breed and multiply here. The following is a detailed explanation from a chlorine sensor Manufacturer!

    Once a large number of bacteria breed, they will consume the residual chlorine in the water. Residual chlorine is an important "guardian" to ensure water quality safety as it can effectively inhibit the growth of bacteria. Once the residual chlorine is completely consumed, the water quality will be seriously threatened.

    The traditional water quality detection method is manual detection, and the detection cycle is quite long. Usually, it is monthly or quarterly sampling inspection. This is like in a battle where we cannot grasp the enemy's dynamics in real - time and can only check the situation at intervals. As a result, the risk of bacterial pollution is highly concealed. By the time we find that the water quality does not meet the standards, the sub - standard water may have already flowed into residents' homes.

    This not only threatens the health of residents but also triggers a large number of complaints. Water supply enterprises not only have to spend a lot of energy dealing with these disputes but also bear high operation and maintenance costs. According to relevant data statistics, the complaint handling costs of some water supply enterprises caused by secondary water supply quality problems can reach hundreds of thousands of yuan a year.

      Core Function: Real - time Monitoring and Accurate Early Warning

    The online residual chlorine water quality automatic sensor is designed to solve these problems. It is specially designed for the closed scenario of secondary water supply. Just like a loyal "sentinel", it is installed at the water inlet and outlet of the water tank.

    It can monitor the residual amount of chlorine in the water in real - time, with a measurement range of 0 - 5mg/L and an accuracy of up to ±0.01mg/L. This means it can very accurately capture the attenuation trend of residual chlorine. Once the residual chlorine concentration is lower than the national standard limit (≥0.05mg/L), it will automatically trigger an alarm.

    This is like having a sharp - eyed "scout" on the battlefield, which can detect the enemy's movements in time and issue an alarm. Compared with the traditional manual inspection, it completely avoids the lag, allowing us to grasp the changes in water quality immediately.

      Scenario Value: Ensuring Water Quality and Reducing Costs

    With the online residual chlorine water quality automatic sensor, it will continuously monitor the residual chlorine data 24 hours a day. Once it detects the risk of insufficient residual chlorine, it will issue an early warning in real - time.

    This early warning signal will be linked with the disinfection equipment, enabling the disinfection equipment to automatically add disinfectants. In this way, it can timely inhibit the growth and reproduction of bacteria, ensuring that the water used by high - rise residents meets the GB 5749 - 2022 standard.

    With the guaranteed water quality, the number of residents' complaints will naturally decrease, and the public opinion risk will also be reduced. At the same time, it also reduces the workload of manual detection and the cost of emergency response. According to the feedback from water supply enterprises using this sensor, the complaint rate has been reduced by more than 70%, and the cost of manual detection and emergency response has been reduced by about 40%.

      Core Protection and Quality Improvement

    In conclusion, the online residual chlorine water quality sensor is the core protection equipment for the "last mile" of secondary water supply. Through real - time monitoring and intelligent linkage, it blocks bacterial pollution at the source, ensuring that there are no blind spots in the water safety of high - rise residents.
