Abstract EN
An Advanced Oxidation Process (AOPs) was carried out in this study with the use of immobilized ZnO and solar/UV as an energy source to degrade dairy wastewater.
The semibatch reactor system consisted of metal plate of 800 × 250 mm and a glass tank.
The reaction time was of 3 h for 3 L of dairy wastewater.
Experiments were performed based on a surface response methodology in order to optimize the photocatalytic process.
Degradation was measured in percentage terms by total organic carbon (TOC).
The entry variables were ZnO coating thickness and pH, using three levels of each variable.
The optimized results showed a TOC degradation of 31.7%.
Optimal parameters were metal-plate coating of 100 μm of ZnO and pH of 8.0.
Since solar/UV is a constant and free energy source in most tropical countries, this process tends to suggest an interesting contribution in dairy wastewater treatment, especially as a pretreatment and the optimal conditions to guarantee a better efficiency of the process.
