Abstract

The revised urban wastewater treatment directive (UWWTD) demands tertiary treatment for plants treating 150.000 p.e. or above. Also, more demanding N and P limits were set, being the new values 8 mg N.L-1 and 0.5 mg P.L-1. Microalgae cultivation shows great promise for this purpose, allowing not only to remove but also to recover N and P, contributing to the circular economy. The aim of this work is to optimize the hydraulic retention time (HRT) in microalgae-based processes to recover nutrients from urban wastewaters.
