Effects of pilot-plant photochemical pre-treatment (UV/H2O2) on the biodegradability of aqueous linear alkylbenzene sulfonate (LAS)
The effects of the photochemical pre-treatment by using a pilot-plant UV/H2O2 process on the biodegradability of aqueous linear alkylbenzene sulfonate (LAS) were studied. It was observed that the photochemical pre-treatment of the LAS solutions by UV-254/H2O2 increased the biodegradability of LAS so...

| description | The effects of the photochemical pre-treatment by using a pilot-plant UV/H2O2 process on the biodegradability of aqueous linear alkylbenzene sulfonate (LAS) were studied. It was observed that the
photochemical pre-treatment of the LAS solutions by UV-254/H2O2 increased the biodegradability of LAS
solutions. Aqueous solutions with higher concentrations of LAS (> 100 mg/L) were non-biodegradable. The
ratio of BOD5/COD of the pre-treated LAS solutions was increased, indicating that the pre-treated LAS solutions
were more biodegradable. This ratio was improved as the LAS solutions were more pre-treated. Also,
the biodegradability factor for the pre-treated LAS solutions was increased as the time of the photochemical
pre-treatment was increased. |
