Abstract: 10Submerged aerated filters (SAFs) treat wastewater to achieve stringent organic carbon and ammonium (NH 4 + ) effluent consents. Currently SAF design follows a black box approach, where inlet and outlet contaminant concentrations are monitored, with little consideration for internal hydrodynamic conditions. Although tracer tests have been used on bioreactors, integrated monitoring of internal fluid velocities, mixing characteristics and process 15 performance has not been established for SAFs. Tracer tests we…
