Ozonation is a wide used technique for waste water treatment at the final stage. Ozone oxidation results in a complex effect of water disinfection, deodorization and decolorization. Ozone oxidizes both organic and non-organic substances in water. However, among other concerns, it is considered to be one of the most expensive treatment methods and, hence, cost optimization together with the increase of treatment efficiency is desirable.

There are known many approaches in ozonation efficiency enhancement. Most of them rely on the synergy effect of ozone combination with other treatments, such as ultraviolet light, chemical detergents (i.e. hydrogen peroxide), ultrasound and others (Amrutlal, 2016). However, introduction of any additional factor with different nature of impact results in increase of plant complexity and cost of maintenance. There are also known few researches on intensification of ozonation processes in a multi-orifice oscillatory baffled column (Lucas et al, 2016). Ozonation in a special design of the oscillated column resulted in significant change of ozone bubbles size and their more even distribution among the column volume. Such approach allows to increase the treatment efficiency by 20% without adding any extra factor with different nature of impact. However, the complex design makes it to be hardly applied for a real usage due to low maintainability of the column.

Thus, this paper aims development of a novel approach in water ozonation intensification by exposure it to vibration at certain resonant frequencies....
