Six application scenarios of online water quality sensor instruments

In the current era of the Internet of Things, big data, and artificial intelligence, online water quality analysis instruments, as an important component of the Internet of Things perception layer, are increasingly required.

Online water quality analysis instruments are a technology for obtaining water quality information, but any field where water is used for human activities is within the scope of application of online analysis instruments. Such fields as water quality monitoring, environmental protection, water treatment, industrial production, etc.
Generally, online water quality analysis instruments can be divided into two categories based on their application purposes: monitoring type and process type products.


The typical six application scenarios are as follows:
drinking water safety
Online water quality analysis instruments can be used to monitor water quality parameters in drinking water, such as pH value, dissolved oxygen, turbidity, conductivity, residual chlorine, ammonia nitrogen, etc. They help ensure the safety and hygiene of drinking water. On the one hand, it provides early warning for possible water quality exceeding standards. On the other hand, a large amount of water quality data from the pipeline network can also support the optimization of treatment processes and pipeline water delivery scheduling decisions for water plants.
In the water treatment plant, various water quality parameter analysis instruments (online turbidity, residual chlorine, total chlorine, acidity and alkalinity, etc.) will participate in the automatic dosing and chlorination process control of the plant, greatly improving the level of automation operation.

sewage treatment
In the process of sewage treatment, online water quality analysis instruments can monitor various pollutants in sewage, such as suspended solids, chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, etc. This helps optimize the sewage treatment process and ensure compliance with discharge standards. Water quality analysis instruments provide a basis for enterprises to achieve self discharge of pollutants, declare environmental protection taxes, and conduct real-time environmental inspections to understand the discharge situation of enterprises.
Various online water quality analysis instruments have also been successfully applied in municipal sewage treatment plants.

industrial process control
In industrial production, water quality parameters measured by online water quality analysis instruments will participate in process control to optimize water treatment processes, improve water treatment efficiency, help optimize industrial processes, and enhance production efficiency. Process based online water quality analysis instruments, photovoltaic applications in thermal power plants, petrochemical enterprises, large metallurgical enterprises, papermaking enterprises, semiconductor factories, biopharmaceutical factories, etc.

environmental monitoring
Online water quality analysis instruments play an important role in environmental monitoring. They can monitor water quality parameters in natural environmental water bodies, such as pH, turbidity, redox potential, dissolved oxygen, chlorophyll-a, etc. of rivers, lakes, oceans, etc. Through real-time monitoring and analysis, online water quality analysis instruments help understand the degree of water pollution, assess environmental conditions, and provide data support and warning information for timely adoption of protection and improvement measures.

Fisheries and Aquaculture
Online water quality analysis instruments are of great significance for fisheries and aquaculture. They can monitor parameters such as oxygen content, temperature, pH value, turbidity, etc. in water bodies to ensure a suitable aquaculture environment and provide appropriate water quality management measures to improve the yield and quality of fisheries and aquaculture.

Swimming Pool and Spa Center
Online water quality analysis instruments play a crucial role in monitoring water quality in swimming pools and spas. They can monitor the concentration of disinfectants, pH value, temperature and other parameters in water in real time to ensure water quality safety and hygiene, and ensure the health and comfort of users.
Generally speaking, monitoring type analytical instruments require high data accuracy, but there are many limitations on detection principles and methods. Process analysis instruments require high reliability and stability of the instrument, and generally have a fast response time.
