Can Chlorine and UV be good partners for water disinfection?

Two of the most often utilized techniques for contaminating water are chlorination and UV disinfection systems. These may be used in conjunction to produce some of the cleanest water.

Chlorine is a very effective water disinfectant, but it also has certain drawbacks. Chlorine byproducts can cause human cancer and have a detrimental effect on aquatic life. Without a secondary disinfectant, a variety of microorganisms that are resistant to chlorine may still remain in the water. UV disinfection is useful in this situation.

You may make sure that there are no dangerous byproducts or microorganisms that are resistant to chlorine by installing a UV system as a secondary disinfection. Installing a UV system downstream from a chlorine filter will make it even simpler for the UV system to function in applications for drinking water, such in the video below.

Swimming pools are another another setting in which UV disinfection and chlorine may work well together. Given the surge in waterborne illness outbreaks brought on by parasites that are resistant to disinfectants, the Model Aquatic Health Code (MAHC) emphasizes the necessity for a secondary disinfection system. The goal of secondary disinfection is to cut down on the amount of time that hazardous germs are exposed. The MAHC recommends ultraviolet (UV)-based and ozone-based secondary systems as two examples. It has been discovered that treating 100% of the recirculated water flow with UV is quite effective in bringing the number of live Cryptosporidium oocysts below the infectious threshold. Microorganisms are destroyed by UV radiation by changing their DNA structure and obstructing cell division. Using a high dosage UV beam with a water filtration system can be an effective secondary line of defense for battling dangerous microorganisms and managing RWI outbreaks.
