ABSTRACT
Our study used a photocatalytic oxidation process for degrading slaughterhouse wastewater
(SHWW). Characterization of the wastewater before and after treatment with TiO2 and Ag-TiO2 in terms
of BOD, COD, and nitrogen was done. The effect of hydrogen peroxide, ozone, and various operating
parameters such as catalyst dose, pH, and reaction time on the degradation efficiency of the process were
also investigated. An increase in catalyst dose and reaction time increased process efficiency. However,
process efficiency was decreased with elevating pH. The results also revealed that the type of catalyst
and their operating parameters have significant influence on the oxidation of SHWW. Ag-TiO2-H2O2
catalyst under UV (400watt) irradiation was found to be best for the degradation of SHWW and resulted
in 95% BOD, 87% COD, and 74% nitrogen removal.
