Abstract
Disinfection is one of the last processes in waste water treatment plants before the effluent is discarded. Its goal is to rid of any potential pathogens, suspended solids, organics or any contaminants. The current, most widely used disinfection method in waste water treatment plants nationally is chlorine disinfection. It is a well-established and cheap technology. Even though it is an effective method for pathogenic microorganism disinfection, it does have certain health and safety limitations, along with environmental concerns. In this study we observe an alternative technology, Ultra Violet (UV) disinfection. We explore the type of microorganisms and pathogens that are destroyed with UV disinfection. The data investigates the wavelength required to achieve complete disinfection, flow rate required and the effects that the chemistry of effluents might have on the disinfection efficiency. Statistical analysis is conducted using SPSS and crystal ball software. SPSS was used to compile the data used from peer-reviewed papers and to create regression equations between flow characteristics, pathogen concentration, and UV disinfection efficiency to understand the relationship between each variable. Crystal ball is used to define the confidence interval of the analytical values. After analyzing the efficiency of UV distinction, it can be concluded that UV disinfection is efficient to remove these pathogens as effective as chlorine but unlike chlorine it does not have any by products or environmental disadvantage. UV disinfection is cost effective and a great alternative to chlorine for removing pathogens from waste water.
