Computer Simulation Optimizes Design of UV Disinfection Reactors
by Eugen Nisipeanu and Muhammad Sami   Pages: 

Computer simulation can substantially improve the design of ultraviolet (UV) technology used to disinfect water. In UV disinfection design, bacteria and viruses must flow in close proximity to a UV lamp for a sufficient period of time to greatly damage DNA, which adsorbs UV radiation. Without a method to determine the effectiveness of a proposed UV system design, engineers have often been forced to over-design systems to ensure their ability to meet regulatory requirements, substantially increasing their cost.
