Detection of drinking water analysis parameters

Baijia.net - a professional third-party testing and inspection platform that provides related testing and inspection services such as drinking water a

Drinking water refers to the drinking water and domestic water used for human life. The current "Hygienic Standards for Drinking Water" (GB5749-2006) set strict hygiene requirements for the quality of drinking water, namely: ① good sensory properties: transparent, colorless, without odor or odor, and without visible objects to the naked eye; ② Epidemically safe: free from pathogenic microorganisms and parasitic eggs; ③ Chemical composition is harmless to humans: The chemicals contained in water do not cause acute, chronic, or long-term harm to the human body. Today, the editor will take everyone to understand the indicators for routine testing of drinking water

Sensory indicators:

Sensory indicators include chromaticity, turbidity, odor, and visible matter to the naked eye.

. These indicators are basic indicators in the quality control of purified water, and the standard values formulated refer to the standards for drinking water (i.e. tap water)

Physical and chemical indicators:

The most important physical and chemical indicators are conductivity and potassium permanganate consumption. Conductivity is a characteristic indicator of pure water, reflecting its purity and the quality of production process control. Water with lower conductivity is purer. Potassium permanganate consumption refers to the milligrams of oxygen consumed by reducing substances in 1L of water when oxidized by potassium permanganate under certain conditions. It mainly examines the content of organic matter, especially chloride, in the water
