Abstract

A two-stage system was designed for microalgae cultivation and nutrients removal.

Two species of microalgae were cultivated for biomass production.

UF costed less than centrifuge for harvesting microalgae at small scale.

100% NH4+ of the wastewater was removed and met discharge requirement.
