Abstract text Novel micro-orifice diffuser concepts and dynamic aeration for enhanced efficiency of biological treatment are proposed. Micro-orifice diffusers have up to 22% higher oxygen absorption at 51% less power demand compared to conventional spargers. Pulsed aeration modes show an increase of kLa by up to 24% and a potential reduction of the gas flow rate by 16% compared to continuous aeration.
