Guar Gum (GG) is one of the problematic water pollutants connected to hydraulic fracturing. There is a pressing need to investigate appropriate unit operations that can be employed to protect the aquatic environment. This study investigated the use of light-emitting diodes (LEDs) in the advanced oxidation process (AOP) of GG. Chemical oxygen demand (COD) removal provided mixed results, depending on the concentration of hydrogen peroxide (H2O2) in solution, and was between (0-95%) for H2O2-to-GG ratios between 7.0 and 176.3 g H2O2/g GG. COD removal was greatest at the …
