When it comes to water quality monitoring, it will involve its standards. In the process of monitoring water quality, through such standards to determine whether the water quality is normal, to determine the normal before use! This chapter water quality online monitoring instrument manufacturers will understand together with you the water quality monitoring indicators are based on what standards to come!

What are the Conventional Indicators of Water Quality? Details are as Follows:

· Microbial indicators: Thermostable Escherichia coli group, total number of colonies, total Escherichia coli, Escherichia coli, etc.;

· Toxicity index: heavy metals (such as arsenic, selenium, cadmium, chromium, lead, etc.), special pollutants (such as fluoride, cyanide, formaldehyde, chlorite, chlorate, nitrate, etc.);

· Sensory properties and general chemical indicators: chroma, total hardness of heavy metals (iron, manganese, copper, zinc, etc.), visible objects, pH of aqueous solution, turbidity, etc.;

· Emission index: total alpha (alpha) radioactivity, total beta (beta) radioactivity;

· Indicators of drinking water disinfectants: residual chlorine, ozone, monoammonium chloride, chlorine dioxide;

So what criteria should be used to determine whether these indicators exceed the standard?

It is understood that “drinking water sanitation standard indicators.” Among the water quality indicators of GB5749-2006, some are routine monitoring indicators, and some are unconventional monitoring.

Conventional indicators are indicators that reflect the basic status of drinking water quality, the detection rate is high, and the projects that can monitor water quality online are classified in the above 5. In addition, each region will incorporate some unconventional indicators with high risk of exceeding the standard into routine projects according to the local water quality, and determine the monitoring frequency. According to the personnel of the relevant departments, the health ministry will carry out sampling monitoring twice at various points in the annual rainy season and dry season, combined with key pollution factors, including key water supply households and water users, etc., and the monitoring project is still based on routine. At the same time, according to the relevant provisions, the water supply unit should carry out real-time online monitoring of water quality, the detection indicators in addition to some mandatory conventional indicators, but also include unconventional, very conventional indicators are selected by the staff of the relevant local departments to negotiate and determine, once found abnormal timely treatment measures!

There is also the health and family planning administrative department will, in accordance with the “Law on the Prevention and Control of Infectious Diseases” and the “Measures for the Supervision and Administration of Drinking Water Hygiene”, and then according to actual needs, regularly carry out water quality and sanitation supervision of major water supply sites and standardize health management. Investigate and punish illegal acts according to law, and timely report to relevant departments when drinking water quality is abnormal.

As for the detection of water quality online monitor is divided into a variety of different indicators of the instrument used will also be different! For example: monitoring biological toxicity in water requires WTox-8000 biological toxicity online analyzer, monitoring the residual chlorine content in water is used to RCl900 total residual chlorine online analyzer, etc., so it is to see what indicators you need to detect to set the instrument!
