Potential use of ultrasound in water disinfection


Ultrasound has been used long enough in engineering and medicine for diagnostics, visualization of underwater objects, surface cleaning and other systems. Using ultrasonic disinfection as a main or additional technology is impractical because of the long exposure time, high energy consumption and lack of regulatory documents. To improve the efficiency of disinfection equipment the manufacturers suggest additional ultrasonic water treatment in combination with oxidi­zers and UV irradiation. The data on possible use of ultrasonics both as an additional disinfection method and method of improving the efficiency of traditional technology from the point of view of the concept of establishing numerous barriers during disinfection is presented. Different types of ultrasonic effect for using in water disinfection systems are considered. Ultrasound provides for the extremely low disinfection efficiency compared to other traditional technologies, therefore it is not used as an independent method. Ultrasonic water treatment improves the efficiency of oxidation technologies. Combined action of ultrasonics and UV irradiation does not have any synergistic effect. For natural water and effluent after treatment according to the operating standards the standard UV dosages are sufficient to ensure meeting the mic­robiological standards. Additional ultrasonic treatment is advisable under special conditions. Quartz sleeves can be well cleaned with mechanical systems and chemical wash which is used by all the world leading manufacturers. Due to the particular hazard of ultrasonic contact impact on humans the process of ultrasonic treatment shall completely eliminate such potential effect.
