A Fresh Take On Biological Wastewater Treatment

09_Jeff_Kelly

Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and mixing cycles without clogging. Managed by oxidation-reduction potential (ORP) readings, the novel technique supports a biological selection process that encourages the exclusive growth of facultative anaerobes — the most resilient wastewater microbes, which get rid of phosphates and nitrates without producing hydrogen sulfide.
