Summary

This review critically examines the effects of light parameters on nitrogen removal performance in microalgae-bacteria symbiosis systems used for wastewater treatment. The paper covers nitrogen removal mechanisms driven by artificial illumination and highlights the role of light as the dominant factor controlling system performance and efficiency.

The littering of nitrogen into water bodies has led to several adverse effects on the environment. “Nitrification-denitrification” is still a prevalent method for removing nitrogen from water bodies, which demands high energy consumption and complex operational conditions. In recent years, MBS has attracted much attention because of its advantages in recovering nitrogen, emitting oxygen, and capturing CO2. It has been proven that light is the top factor influencing the performance of MBS. This paper will critically review the effects of light parameters on nitrogen removal by MBS, and the nitrogen-removal mechanisms of MBS driven by artificial illumination.
