Apparatus and method for wastewater nutrient recovery

摘要

An apparatus for treating a secondary treated wastewater effluent. The apparatus comprises an anoxic first zone for accepting the secondary effluent wherein the first zone includes heterotrophic bacteria, a carbon source, and an outlet structure including a limestone aggregate. The apparatus further comprises a second zone including an entrance structure that is in fluid communication with the outlet structure and an exit structure in fluid communication with the second zone. The exit structure includes a cationic exchange medium wherein the exit structure discharges the effluent to a disposal mechanism such as a subsurface disposal field.
