[Chemical Knowledge]：How to remove chlorine ions in water

Read： 1870 Time：20months ago Source：Transform the World with Simplicity

Chloride ion is a chemical substance commonly found in tap water and groundwater, and its harm to human health and the environment cannot be ignored. In daily life and industrial production, we need to take certain methods to remove chloride ions in water to ensure the safety and quality of water. This article will introduce some common methods to remove chloride ions from water.

1. Activated carbon adsorption

activated carbon is a highly adsorptive material that can adsorb chloride ions, organic matter and other pollutants. Add activated carbon to water, chloride ions will be adsorbed on its surface, so as to achieve the effect of removal. This method is suitable for small-scale and low-concentration chloride ion removal, but the effect will be significantly reduced for high-concentration chloride ions.

2. Reverse osmosis technology

reverse osmosis technology is a method of reverse osmosis under high pressure, which can effectively remove chloride ions and other impurities in water. Under the action of the reverse osmosis membrane filter, the water passes through the membrane filter with high pressure, the chloride ions and other harmful substances in the water will be isolated on one side of the membrane, and the clean water will flow into the other side. Compared with other methods, reverse osmosis technology has the best effect of removing chloride ions, but its cost is higher and it is suitable for production and large-scale water use.

3. ion exchange technology

ion exchange technology is a common water treatment method, which uses polymer resin to adsorb and replace ions, so as to remove chloride ions in water. This method is divided into anion exchange and cation exchange, according to the actual situation to choose the appropriate ion exchange method. Ion exchange technology is suitable for small and medium-sized water treatment and drinking water treatment, but its operation process is complicated.

4. ultraviolet disinfection method

ultraviolet disinfection method uses ultraviolet light to irradiate microorganisms and viruses in water, so as to achieve the purpose of sterilization and disinfection. In this process, the action of ultraviolet light can also remove chloride ions and other oxidizing pollutants from the water. This method is suitable for small and medium-sized water treatment and drinking water treatment, but it has higher requirements for water quality, and it is necessary to ensure that there are not too many suspended solids and organic matter in the water.

To sum up, there are many ways to remove chloride ions in water, and the most suitable method can be selected according to the actual situation and needs. No matter what method we use, we need to ensure the quality and safety of water and take responsibility for our own health and that of others.
