Vibroresonant Effects for Enhanced Ozonation of Wastewater
Ozonation is a wide used technique for waste water treatment at the final stage. 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. This paper aims development of a novel approach in water ozonation intensification by exposure it to vibration at certain resonant frequencies. During such treatment specific processes arise, which are called vibroresonant effects. The experiments were carried out on a lab bench that consisted of a simple column was installed on a shaker. They have showed that exposure to vibration at certain resonant frequencies makes the ozone bubbles smaller, while increasing their total quantity in water and improving their even distribution among water column. This increases specific phase boundary area and improves treatment efficiency without adding any extra impact factor. It was found, that at certain treatment modes COD reduction has increased by 30% compared to sole ozonation without vibration and reached 57% in total.
