The Development of Online Water Quality Analysis Instruments

Since the beginning of the 21st century, due to the increasingly serious problems of water scarcity and water environmental pollution, the water industry has faced many challenges and opportunities such as rising water resource costs, improved drinking water quality standards, stricter wastewater discharge standards, increased water consumption and population, and rising water prices. Under the pressure of regulations and market promotion, the elimination of extensive water treatment and usage models, and the adoption of more advanced automatic control systems to achieve water treatment automation, thereby improving water treatment efficiency and reducing water management and usage costs, has become an inevitable choice for the water industry. At the same time, key equipment in the automatic control systems involved in the water treatment industry -Online water quality analysis instrumentThe manufacturing and application technologies have also rapidly developed with the advancement of disciplines such as analytical chemistry, materials science, and computer technology; The stability and reliability of instruments have greatly improved, and the convenience of instrument use has also made significant progress. More and more water quality parameters can be monitored online·Online water quality analysis instrumentThe power is also becoming stronger and stronger. At the same time, the Organization for Standardization (ISO) has established a standard with the code name "Water Quality Specification and Performance Testing for Online Water Quality Analyzer Analysis Equipment" (ISO 15839-2003), which defines the performance characteristics of online water quality analyzers and establishes testing procedures for evaluating and determining performance characteristic parameters. This universal standard establishes a testing program for evaluating and determining performance characteristic parameters of online water quality analyzer 4 based on its performance characteristics. This universal standard provides a basis for the research, production, and collection of online water quality analysis instruments, thereby providing a technically reliable guarantee for the full application of automatic control systems based on online water quality analysis instruments in the water industry. More and more online water quality analysis instruments are being used in water treatment industry automation control and wastewater discharge monitoring today.
