What are the current technologies that can effectively remove residual chlorine in water

The water that enters the body daily includes not only direct drinking water, but also cooking water. If you just use bottled water to improve direct drinking, the water used for cooking actually enters the human body without being filtered. Since consumers have chosen bottled water, they agree with the concept of healthy drinking water. To truly achieve healthy drinking water, you must ensure that the above two types of drinking water that directly enter the body are safe and healthy. Therefore, installing a water purifier is a good choice.

The current technologies that can effectively remove residual chlorine in water include: RO water purifier, residual chlorine ball purifier, activated carbon water purifier, KDF water purifier, ultrafiltration water purifier, medical stone purification and other technologies. According to the experimental results, the residual chlorine removal effect of normal tap water is as follows:
1. Maifan stone has a purification function that can absorb part of the residual chlorine molecules, and can remove 5-10% of the residual chlorine of the bleaching powder for a duration of 1-3 months.
2. The ultrafiltration membrane has a filtration accuracy of up to 0.01 microns, which can filter bleaching powder and free molecular residual chlorine, with a residual chlorine removal rate of 10-20% and a long service life.
3. Activated carbon's super adsorption capacity can absorb most of the bleaching powder and residual chlorine, and the removal rate of residual chlorine can reach 90-95%. The higher the iodine value, the stronger the adsorption capacity of the activated carbon, the higher the removal rate of residual chlorine. The adsorption of a single substance is easy to saturate, and the duration is about 1-2 months.

4. The RO reverse osmosis water purifier series products integrate international advanced RO membrane technology, a purely physical filtration method driven by pressure, and a five-stage filtration combination with a filtration accuracy of up to 0.0001 micron, which can not only filter many kinds of water that are harmful to the human body The radioactive elements, especially heavy metal ions such as lead, arsenic, mercury, and cadmium, residual chlorine, pesticide and fertilizer residues, bacteria, viruses and other microorganisms can be thoroughly filtered, and the residual chlorine removal rate is nearly 100%.
5. The residual chlorine ball purifier, the chemical composition is calcium bisulfite CaSO3, which is mainly a chemical reaction, and the amount should not be too high. Its main function is to remove residual chlorine in the water body, including chemical residual chlorine and free residual chlorine ClO- (hypochlorite ion), HOCl (hypochlorous acid), Cl2 (chlorine gas), etc., change the chlorine element in tap water into an element that is harmless or beneficial to the human body. The removal rate is close to 100%, and the service life is 8-12 months.
