Post-Aeration

Post-Aeration and Chlorine Contact Chambers

High level disinfection of the effluent is provided in the post-aeration/chlorination tanks. A chlorine residual of over 1.0 mg/L is maintained. The chlorine is then removed by addition of sulfur dioxide prior to discharge to Hillsborough Bay.  If the effluent is reused, the chlorine is not removed.
