Strictly speaking, resin is called soft water.
The resin purifies the calcium and magnesium ions present in the water by replacement, thereby reducing the hardness of the water.
It is generally recommended to use this type of water as bathing water and for other equipment.
If you drink water yourself, you should always use water from a water purifier or pure water machine.
If you are in Chengdu area, it is recommended to go to Meijing HVAC.
1. Distillation Method: Currently used distillers are made from glass, quartz, copper and other materials. The distillation method can only remove non-volatile substances in water, but cannot remove gases dissolved in water. , depending on the preparation materials, the types and amounts of impurities contained are also different. For example, if a copper still is used, the water cwill contain a small amount of copper ions, and if a glass distiller is used, the water will. contains a small amount of sodium ions and silicate ions. From an economic point of view, distilled water has the disadvantages of high water consumption and high electricity costs. If it is in a remote area, transportation will also be a problem, especially for people. glass and quartz water distillers. 2. Ion exchange method Prepared by ion exchange method Pure water is called deionized water. This is a method that is commonly used today. The advantages of this method are: low cost, the resin can be regenerated and used repeatedly, and the amount of water prepared is large and has strong deionization capacity, but each method has disadvantages, and the method reverse osmosis system is no exception. are that the equipment andoperation are complicated, and it cannot remove non-electrolytic impurities such as organic matter, and there are traces of resin dissolved in water. 3. Dialysis Method Dialysis is also called osmosis method which uses anion. and a cation exchange membrane for selectively impregnating ions in a solution under the action of an external electric field to separate impurity ions from water. The most commonly used method now is reverse osmosis technology, reverse osmosis can remove 90-99% of most pollutants. but the impurity removal efficiency is relatively low. If used alone, it is only suitable for certain undemanding experiments. It is generally used as a preprocessing method.
