      Maideshi, a chlorine sensor Manufacturer, fully understands that in the daily operation of municipal waterworks, controlling residual chlorine is a major headache. During the disinfection of tap water, the residual chlorine content must be just right. If the residual chlorine level is too high, the tap water will have an unpleasant odor. When residents use such water to take a bath, they may feel skin irritation. Who would want to use such water? It will definitely lead to dissatisfaction and complaints from residents. On the other hand, if the residual chlorine level is too low, the disinfection will be incomplete, and there is a risk of microbial over - standard in the water, which poses a potential threat to residents' health and also attracts complaints.

      Previously, most waterworks adopted the traditional offline monitoring method. Workers would manually take samples at regular intervals for testing, but the test results were often delayed by 1 - 2 hours. During this 1 - 2 - hour period, the residual chlorine in the pipeline network could fluctuate significantly due to changes in pipeline pressure and water volume. This is like "waiting for a hare by the stump", making it impossible to adjust the chlorine dosage in time according to the actual situation. For example, if the pipeline pressure suddenly changes and the residual chlorine content also changes accordingly, but since the test results are not available yet, the staff still add chlorine according to the original dosage, which can easily lead to either too high or too low residual chlorine levels.

      Moreover, with the increasingly strict supervision nowadays, residual chlorine is a mandatory water quality indicator, and relevant data need to be uploaded in real - time. The offline monitoring method is prone to data gaps. Once discovered by the regulatory authorities, the waterworks will face compliance risks and may be punished.

      At this time, the online residual chlorine automatic sensor acts like a "precise early - warning sentinel" and plays a huge role.

      1. Real - time Monitoring

      It continuously tracks the residual chlorine concentration in the pipeline network 24 hours a day, and the monitoring accuracy can reach 0.01mg/L. The monitored data is synchronously displayed on the central control system. As long as there is the slightest fluctuation in residual chlorine, the staff can immediately notice it. It's like equipping the waterworks with a pair of "all - seeing eyes" to constantly monitor the changes in residual chlorine.

      2. Intelligent Early - warning Function

      Once the residual chlorine deviates from the standard range, for example, the residual chlorine standard for domestic drinking water is 0.05 - 4mg/L. As long as the residual chlorine content exceeds or falls below this range, the monitor will immediately issue an audible and visual alarm, and at the same time, it will push the early - warning information to the manager's mobile phone. In this way, no matter where the managers are, they can be informed of the abnormal residual chlorine situation in the first place.

      3. Linkage with Chlorine - adding Equipment

      When the monitored residual chlorine content is low, it will automatically adjust the frequency of the chlorine - adding pump to increase the chlorine dosage; when the residual chlorine content is high, it will reduce the chlorine dosage. This avoids the lag of manual adjustment and ensures that the residual chlorine content is always within the standard range.

      For waterworks, the online residual chlorine monitor brings tangible value. Firstly, it ensures the stability of water quality. Previously, it was "post - adjustment", that is, solving problems after they were discovered. Now it has become "real - time control", which can detect changes in residual chlorine in time and make adjustments, greatly reducing residents' complaints about water quality and maintaining the enterprise's reputation.

     Secondly, it can also reduce operating costs. Precise chlorine addition avoids the waste of chemicals. For a waterworks with a daily water supply of 100,000 tons, it can save tens of thousands of yuan in costs per year.

      The safety of tap water is a matter of great concern to thousands of households. The online residual chlorine monitor is like a dedicated "early - warning sentinel", making the residual chlorine control in waterworks more precise and allowing residents to drink water more safely. If you are also interested in a more advanced and intelligent water quality monitoring method, welcome to consult Maideshi, a manufacturer of digital residual chlorine sensors and online residual chlorine detectors!
