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.
