Abstract:
Sonolysis effects are based on ultrasonic cavitation which means generation of very reactive radical especially hydroxyl radical. Its high oxidation potential makes sonolysis one of the best advanced oxidation methods for removal of micropollutants from drinking water sources. Ammonia ions are often present in groundwater sources and must be removed because it favors microorganism development. Chlorination and biological nitrification are the well-known methods for ammonia removal from drinking water. This paper emphasized the alternative of ultrasonic and chlorination for advanced removal of ammonia ions. Laboratory tests have shown 80% ammonia removal efficiency for 9 mg NH4+/L initial concentration for 8.5 reaction pH.
