- E. coli is a bacteria indicating the presence of contamination in clean water. This research aims to design a tool to eliminate E. coli bacteria, so water well worthy citizens for the purposes of everyday. Photolysis process with variations in reactor diameter of 2.5 ", 3", and 4 "in the detention time 20, 40, 60, 80, and 100 minutes will be used to eliminate the bacteria E.coli. Photolysis process in this reactor using ultraviolet light 10 watts, λ = 365 nm. analysis of the data used is the correlation between the allowance of E.coli with photolysis process variations and combinations of reactors. E.coli preliminary results reached 80% in the detention time of 100 minutes in the reactor 2.5 ". Whereas in the photolysis of the detention time of 100 minutes with reactor 3" allowance of E.coli reached 79%. And the allowance of E.coli reach 77% in 100 minutes detention time at reactor 4 ". Key words : E.coli - Photolysis - UV intensity - Variations Reactors
