Wahaso - Ultra Violet (UV) Sanitation System

For many rainwater applications, ultraviolet sanitation (UV) is sufficient for killing pathogens that could present a health risk. These systems expose the water to a specific wavelength of UV light that destroys the DNA of any organisms present. Stored water can be constantly circulated past the UV bulbs to protect the entire water supply, or exposure can take place right before application. The biggest advantage of UV sterilization is that it is chemical-free and requires minimal maintenance. Its biggest disadvantage is that the UV has no residual killing effect – so that algae and other pathogens can still form down stream of the system. Sizing of the UV system is critical to maintain sufficient exposure rates to keep the water sterile.
