    Time:September 28, 2025


    For water treatment plants, ensuring that the water quality at the end of the distribution system meets the standards is a crucial task. Among various factors, the residual chlorine content is one of the important indicators to measure the safety of water quality. However, the problems with the membrane of the online residual chlorine analyzer often put the work of ensuring the water quality at the end into a difficult situation. Here, the manufacturer of residual chlorine water quality monitors will explain it to you in detail!

      Pain Point Analysis: The Root Cause of Failing to Ensure End Water Quality

    Online residual chlorine analyzers play a vital role in the water quality monitoring of water treatment plants. However, when the membrane of the residual chlorine analyzer is exposed to dry air for a long time, just like a person getting thirsty without drinking water for a long time, it is very prone to cracking.

    This small crack can bring about big troubles. After the membrane cracks, the detection data will be falsely high. Even though the residual chlorine in the pipeline network has been exhausted, the instrument misjudges that it meets the standards. It's like a "messenger" who only reports good news but hides bad news, transmitting wrong information. Due to inaccurate detection data, the disinfection work of the water at the end will be insufficient. Bacteria are likely to grow in such an environment. When residents turn on the tap, they may find that there is a problem with the water quality.

    Statistics show that cases of residents' complaints due to bacteria growth caused by insufficient residual chlorine are not uncommon. Some water treatment plants may also face penalties for failing the water quality spot - checks. This not only affects the residents' water - using experience but also brings economic and reputational losses to the water treatment plants.

     The Key to Solving the Problem: The Core Role of Membrane Moisturization

    To solve the problems caused by membrane cracking, "membrane moisturization" is the core. There are two types of online residual chlorine analyzers on the market: ordinary ones and moisturizing ones. The moisturizing online automatic water quality monitoring instrument is equipped with an automatic spray moisturizing system, which is like a considerate "small kettle" for the membrane.

    When the instrument is shut down, it will regularly moisten the membrane with pure water to keep the membrane always in a moist state. At the same time, it is also equipped with a sealed protective shell, which further reduces the contact between the membrane and dry air. The service life of the membrane of an ordinary model may be only one month, while that of a moisturizing model can be extended to three months. Moreover, the data error of the moisturizing model can be controlled within ±0.02mg/L, greatly improving the accuracy of detection.

     Selection Points: Selection Criteria for Ensuring End Water Quality

    When selecting an online residual chlorine analyzer and an automatic residual chlorine sensor, in order to better ensure the water quality at the end, the "end - protecting" selection criteria should be followed. First of all, give priority to models with intelligent moisturizing start - stop functions. This can automatically adjust the moisturizing mode according to the detection intervals, which is more energy - efficient. Secondly, instruments that allow tool - free membrane replacement are very popular. This can save a lot of maintenance time and make the work of the staff easier. Finally, models that support linkage adjustment with the chlorination pump are also very important. When the detection data shows that the residual chlorine content is low, it can automatically control the chlorination pump to supplement chlorine, ensuring water quality safety in a timely manner.

     Effect Verification: Real - life Cases Prove the Strength

    A certain municipal water treatment plant used to use ordinary residual chlorine analyzers, and there were continuous problems with the water quality at the end. Residents' complaints were constant, and the water treatment plant staff were in a complete mess. Later, they switched to a moisturizing online residual chlorine analyzer. The effect was immediate. The compliance rate of residual chlorine in the end pipeline network increased from 82% to 99%. Residents no longer had to worry about water quality problems, and the number of water quality complaints decreased from 15 per month to 0. Moreover, the cost of membrane replacement was reduced by 4000 yuan per year.
