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
