Recirculation of flow from within a wastewater treatment system has been utilized as a tool for decades. This one-hour class will look at the benefits of recirculating water from the back of your lagoon system to the front; including how and why it can improve BOD removal, reduce algae, lower nitrate levels, increase alkalinity and improve nitrification. We will then investigate the theoretical design from a biological process point of view; how much to recirculate, the benefits/cost of creating a pre-anoxic zone, adding mixing, covers, cycling air, and blending influent flow with recirculated flow prior to returning it to the lagoon. Finally, we will look at how to implement recirculation and present case studies.
