ABSTRACT
Photodegradation of milk solutions (dairy sewage substitutes) occurred both in the presence and absence
of TiO2 photocatalyst, as it was monitored using COD measurements. At lower milk concentration the photoreaction
rates were directly proportional to the concentration. Small additions of hydrogen peroxide
enhanced greatly milk photodegradation, especially in the presence of titanium dioxide photocatalyst.
