What is the difference between pure water and softened water
What is hard water?
Hard water is water containing high concentrations of minerals, especially high concentrations of calcium and magnesium. Also, CaCO3(s) is produced when heated. Therefore, if the tap water is hard water, there will be a white precipitate after heating in the water heater.
1. The content of water is different: soft water contains no or less soluble calcium and magnesium compounds, and hard water contains more soluble calcium and magnesium compounds.
2, soft water is not easy to produce soap scum with soap, and hard water is the opposite. Hard water does not pose a direct health hazard, but it can cause a lot of troubles in life, such as scaling on water appliances, soap and detergent cleaning. Use this to distinguish between hard and soft water.
3. Wash your hair with soft water to make your hair softer and more lustrous. Washing your face with softened water can have a cosmetic effect. It can be said that the softening of domestic water plays a very important role.
4. Hard water can be converted into soft water after treatment. Hardened water treated by softening refers to softened water obtained by reducing the content of calcium salt and magnesium salt to 1.0-50 mg/L. The DC power source is used as a power source to selectively pass ions in the water through the ion exchange membrane to obtain soft water.
5. Generally speaking, "hard water" and "soft water" mainly refer to the content of calcium carbonate and magnesium carbonate, expressed as "mg calcium carbonate / liter of water" or "ppm", which is called the hardness of water.
What is the difference between pure water and softened water?
The difference: pure water can be directly consumed, mainly refers to drinking water. In principle, the softened water from the softened water equipment cannot be used for drinking. It is mainly used for domestic water, and soft laundry is used to make the clothes more vivid, fluffy and soft.
Pure water machine is pure water, it uses reverse osmosis membrane filtration technology, the core is microporous filtration, only water molecules and minerals smaller than water molecules can pass through the filter membrane and remain, bacteria, pollutants, minerals Can not pass the filter membrane to ensure the purity of the effluent water.
The water softener basically adopts the ion exchange technology, and uses the regenerated sodium type resin to replace the easily scaled calcium and magnesium ions in the water, thereby softening the water to achieve the purpose of removing scale.
