Filtration is the process of removing particles from the water, absorbing undesired odors, tastes, colors and organic pollutants, eliminating iron, chlorine, manganese and arsenic, as well as neutralizing the water acidity. Simple in appearance, filtration is in reality a sophisticated water treatment process.

Ultraviolet Water Treatment

Ultraviolet Water Treatment

Culligan’s Ultraviolet Water Treatment (UV) is a physical, chemical-free process that attacks and destroys the DNA of the bacteria directly. This inhibits the bacteria's ability to reproduce and renders them harmless. In addition to killing mircoorganisms, UV water treatment can assist with total oxidizable carbon (TOC) reduction, chlorine/chloramine destruction, ozone destruction and microbial disinfection.
