Research on biological processes for wastewater treatment (WWT) over the past decade has focused on the development of compact treatment processes at the expense of a high energy demand or a loss of valuable nutrients. The recent worldwide interest in the cultivation of microalgae for energy production, along with the need for more sustainable WWT processes, has turned microalgae-based WWT into a promising alternative to bacterial-based processes from an economic and environmental viewpoint. The O 2 produced photosynthetically by microalgae is used for the oxidation of organic matter and NH 4+ , while the autotrophic and heterotrophic metabolism of algal-bacteria consortia can support an enhanced nutrient recovery. This chapter presents a critical state-of-the-art review of the basis and applications of microalgae in the context of WWT in this 21st century.

Abstract
Research on biological processes for wastewater treatment (WWT) over the past decade has focused on the development of compact treatment processes at the expense of a high energy demand or a loss of valuable nutrients. The recent worldwide interest in the cultivation of microalgae for energy production, along with the need for more sustainable WWT processes, has turned microalgae-based WWT into a promising alternative to bacterial-based processes from an economic and environmental viewpoint. The O 2 produced photosynthetically by microalgae is used for the oxidation of organic matter and NH 4+ , while the autotrophic and heterotrophic metabolism of algal-bacteria consortia can support an enhanced nutrient recovery. This chapter presents a critical state-of-the-art review of the basis and applications of microalgae in the context of WWT in this 21st century.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
