Abstract

This article discusses testing results of industrial trial of new wastewater disinfection comprised of combined use of ultrasonic and ultraviolet methods at final stage of wastewater treatment aimed at elimination of pathogenic organisms, thereby preventing spread of infectious diseases. The new method has been developed, patented and tested at one of the leading water service companies: SUE “Vodokanal of St. Petersburg”. The integrated assembly was fabricated at Novotech-ECO and installed at South-West Wastewater Treatment Plant (SWWTP, SUE “Vodokanal of St. Petersburg”). The test results demonstrated efficiency of combined ultraviolet and ultrasonic treatment of wastewater both in terms of disinfection improvement and in terms of the assembly operation stability through prevention of biological films deposition on lamp sleeves. The latter fact served as background of the challenging project on improvement of existing system of ultraviolet disinfection at SWWTP.

Keywords: combined disinfection methods, pathogenic microorganisms, ultrasonic and ultraviolet disinfection, wastewater, water treatment
