Figure 3

E. coli concentration versus fluence for two UV systems. Black circles represent bench-scale treatment at 254 nm using a LP collimated beam system. Yellow squares represent bench-scale treatment at 279 nm using an UV LED collimated beam system. The red dotted line represents target effluent concentration to meet regulatory discharge requirements. The black line and shaded region represent the mean and 95% confidence interval (n = 12) of the effluent concentration from post UV samples.
