The DLR UV water purifiers are capable of treating small to mid size water flow projects. Ultraviolet (UV) disinfection is a proven, dependable and effective method for eradicating microorganisms present in the water source. UV radiation with 253.7 nanometer wavelength is extremely effective in killing microorganisms such as bacteria (E. coli), viruses (poliovirus, influenza, hepatitis), protozoan cysts (Cryptosporidium, Giardia Lamblia), yeasts and molds. UV in this range targets the DNA of the microbial contaminants and renders them non-viable.
