Under normal circumstances, pure water (such as distilled water) has no taste and odor.However, in our daily life, no matter it is tap water, bottled water or even bottled water, there can be some odor in the water, more or less. Your initial reaction may assume your water supply has been contaminated, but there are several reasons why your household water may suddenly possess a bad odor. So the question is: What cause the bad smell?
How does different ingredients influence the taste of water?
- Hardness: Converting calcium and magnesium ions in water to calcium carbonate is the hardness of water. When the hardness is too high, water tastes bad and has odor in it; when the hardness is too low, the water will not have a sweet taste.
- Total dissolved solids: Total dissolved solids refer to the total amount of solid matter in water that can be dissolved in water, which is also known as evaporation residue This includes minerals such as calcium, magnesium, sodium, potassium, and chloride, carbonate, citrate, sulfate, and some organic matter. When there is too much MgCL2 and CaCL2, the water possess a bitter taste.
- Carbonate: Carbonate gives the water a refreshing taste, but when it is too high, it makes the water lose its proper taste.
- Chloride ion: The chloride ion content is too high and has the same taste as the salt. Groundwater in coastal areas is often affected by seawater, resulting in excessive chloride ion content and unsuitable for drinking.
- Iron: When there is a lot of iron in the water, it will feel rust and smell, and it will also stain clothes and water delivery equipment.
- Residual chlorine: In the process of disinfection and transport of tap water, in order to inhibit the reproduction of microorganisms, it often contains a certain amount of residual chlorine, which has a bleaching taste.
- Artificial pollutants, such as industrial wastewater, pesticides, etc.: Anthropogenic pollution includes many, such as phenol (such as: organic chemical raw materials), dimethyl trisulfide (such as pesticides), nitrite (such as: preservatives) and organic matter.
How to improve the taste of water?
Generally speaking, when tap water is delivered from the factory, the water quality can meet the requirements of the national standard. However, due to the water pipe and the secondary water supply pollution, the water output of the user tap is not up to standard.
The good water purification system can not only filter physical pollution in water, such as rust, sediment, colloid, solid impurities, etc., but also filter out chemical pollution such as residual chlorine, organic matter and inorganic substances in the water, as well as algae and bacteria. Biological pollution such as red insects and sand worms makes the domestic water fresh and clean, and enhances the taste of the water.
