With the rapid advancement of science and the continuous improvement of people’s living standards, all walks of life are also constantly developing and progressing. The development history of the water quality testing industry is quite remarkable. The following online water quality testing instrument manufacturers will share with you the development history of the water quality testing industry.
Among them, the water quality standards for domestic drinking water are related to multiple factors such as human living habits, the level of scientific and technological development, and culture. There will be certain differences in water quality requirements in different places. The main consideration for drinking water is its impact on human health. Besides chemical and physical indicators, this standard also includes microbial indicators, etc. As for industrial water, what needs to be considered is the quality of the product. Water quality testing plays a significant role! As for the water quality testing industry, its development is greatly influenced by policies. Judging from the current situation, the entire industry is developing rapidly.
Relevant Policies Concerning the Water Quality Testing Industry
The water quality testing industry should abide by the “Environmental Protection Law of the People’s Republic of China”, the “Law of the People’s Republic of China on the Prevention and Control of Water Pollution”, the “Administrative Measures for the Operation Qualification License of Environmental Pollution Control Facilities”, the “Surface Water Environmental Quality Standards”, the “Regulations on the Prevention and Control of Pollution in Drinking Water Source Protection Areas”, the “Administrative Measures for New Products of Measuring Instruments”, the “Administrative Measures for the Operation of Automatic Monitoring Facilities for Pollution Sources”, and the “Pollution Control Standards” Laws and regulations such as the “Measures for the Administration of Automatic Monitoring of Pollution Sources”, the “Measures for the Administration of Operating Qualification Permits for Environmental Pollution Control Facilities”, the “Measures for the Review of the Validity of Automatic Monitoring Data of Pollution Sources of National Monitored Enterprises”, the “Regulations for the Supervision and Assessment of Automatic Monitoring Equipment of Pollution Sources of National Key Monitored Enterprises”, and the “Measures for the Administration of Environmental Monitoring”.
Technical Level and Characteristics of the Water Quality Testing Industry
If we only look at the current situation of water quality testing equipment, the technical level of China’s water quality testing instrument industry still needs to be improved, and the development issues are relatively weak. The main standards lie in the reliability and stability of the products. This has led some users to choose imported products, especially large and precise instruments and core control system technologies in complete projects. This means that for some water supply enterprises, the cost of investing in water quality testing equipment is high, which is unaffordable for some small enterprises. So the overall level of water quality testing equipment still needs to be improved to ensure water quality safety.
Development of Water Quality Testing
In 2011, there were over a hundred enterprises in China that produced online water quality testing equipment. The water quality testing industry in China started relatively late. Judging from the current products, they are relatively monotonous and the quality is not yet stable enough. Some enterprises still have a relatively high degree of product repetition and their technological content needs to be improved. Some core components are still imported. However, the investment in research and development up to now has been greatly affected by market fluctuations. Advanced independent technologies are still left in high-efficiency and research institutes. There is still a lot of room for development in terms of industrialization degree and channels.
In fact, the early installed laboratory water quality analysis instruments were not only inconvenient but also had poor real-time performance. It is precisely for this reason that many enterprises have developed online water quality detection equipment, which can detect the content of water indicators in real time. This is a huge progress!
What Exactly are the Water Quality Testing Indicators?
There are many of these. The main water quality and various pollutant indicators in the water all need to be tested. For example: color, total phosphorus, total nitrogen, turbidity, total residual chlorine, heavy metals in water (cadmium, lead, silver, iron, nickel, etc.), COD (Chemical Oxygen Demand), BOD (Biological Oxygen Demand), TOC (total organic Carbon), biological toxicity, coliform bacteria, total bacterial count, Escherichia coli, etc. It is to conduct real-time monitoring of its parameters based on different water quality conditions.
