【Chemical Machinery Equipment Network Hot Concern ] Recently, a study showed that drinking water in many cities and regions in China contains high concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS).
PFAS is usually used in the manufacture of coatings for clothing and food packaging.
It is resistant to heat and oil, but it is also a substance harmful to the human body.
Hot attention of Chemical Machinery Equipment NetworkChemical machinery and equipmentPFAS is usually used in the manufacture of coatings for clothing and food packaging.
It is resistant to heat and oil, but it is also a substance harmful to the human body.
Researchers reviewed 526 drinking water samples in 66 cities, and more than 40% of the cities had drinking water PFAS levels that exceeded the limit level issued by California in 2019.
The drinking water PFAS levels in eastern and southwestern China are even higher.
Zigong, Lianyungang, Changshu, Chengdu, Wuxi, and Hangzhou are cities with high concentrations of PFAS in drinking water.

Water is the source of life, and human beings cannot do without water in life and production activities.
With the rapid economic development and the continuous increase of population, drinking water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development.
With the rapid economic development and the continuous increase of population, drinking water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and social sustainable development.
Drinking water safety has always been the focus of social concern.
With the development of society and economy, residents have gradually increased their requirements for drinking water quality.
In order to better meet the people's demand for high-quality drinking water, in March 2018, the state* and relevant ministries and commissions launched the "Sanitary Standards for Drinking Water" In a new round of revision work, the new standard will incorporate indicators of health hazards into the standard and introduce inspection methods.

In addition, to protect the safety of drinking water,Detector apparatus essential.
From the above research, it is not difficult to see that monitoring of water quality is indispensable.
Online water qualityAnalytical instruments are widely used in water source protection as a common analytical instrument.
Online water quality analysis instruments are mainly divided into monitoring type and process type.
The monitoring type is mainly used to determine whether the water quality meets the standard.
It is a pure water quality monitoring instrument; while the process water quality online analysis and monitoring instrument can reflect the changing trend of water quality and can provide for the treatment of water pollution.
Reliable data support.
Using this type of online water quality analysis and monitoring instrument, relevant staff can protect drinking water in a targeted manner.

In addition, in addition to water quality supervision of water sources, water treatment in water plants is the main link to ensure drinking water safety.
When the water company performs water treatment, it will use an online disinfectant analyzer to monitor the disinfectant content in the water in real time, such as residual chlorine and chloramine analyzers.
This can not only save water treatment chemicals, reduce operating costs, but also ensure that the tap water Without too much disinfectant, the safety of tap water is improved.
In addition, modern analytical instruments such as atomic absorption photometers, atomic fluorescence spectrometers, gas chromatography, ion chromatographs, and other conventional testing equipment, while promoting the improvement of water quality testing technology, ensure the safety of drinking water.
