In the play, Gu Jia uses water related terms such as TDS value and pH value to frighten the ladies into a daze. A water tasting meeting becomes a knock on the door, making her successful in getting into the devil's palace.
Many viewers said that they didn't know what they didn't know. They were scared after watching. They also paid so much attention to drinking water.
TDS
TDS is the abbreviation of total dissolved solids. Its unit is mg / L. it is used to indicate how many mg of dissolved solids are dissolved in one liter of water. The higher the TDS value, the more impurities in the water, the saltier and rougher it will be.
PH value
PH describes the degree of acidity and alkalinity of aqueous solution, expressed by pH value. Under the standard condition of thermodynamics, the aqueous solution with pH = 7 is neutral, pH < 7 is acidic, pH > 7 is alkaline, low pH has corrosive effect, high pH affects taste and has soap taste. The pH value of drinking water should be less than 8.
EPA drinking water quality standard:
Primary water: no specific indicators
Secondary water: pH value is 6.5-8.5
EU drinking water quality standard: pH value is 6.5-9.5
EU bottled or barreled purified water standard: minimum pH value should be reduced to 4-5
Japanese drinking water quality standard: pH value is 5.8-8.6
The hygienic standard of drinking water in China is as follows: pH value is 6.5-8.5
GB 17323 bottled purified drinking water standard: pH value is 5.0-7.0.
Water is the source of life and the foundation of health. Water accounts for more than 70% of human body. People need to drink water every day. Whether drinking water is safe or not is very important to health. TDS and pH value, to some extent, reflect the taste and quality of water.
However, there are many factors affecting water quality, such as water source, transportation process and so on, which will have an impact on water quality.
In recent years, the deterioration of water quality has brought a lot of troubles to human health, and the quality and safety of water are very important.
At present, most of the drinking water in China conforms to the relevant national standards, and the tap water can also be drinkable after being treated by various waterworks processes. However, in the process of transportation, tap water is likely to encounter secondary pollution when it is transported to thousands of households through the water supply network.
Therefore, a healthy and qualified pipeline is essential to the safety of domestic water use.
