This presentation explores wastewater treatment using algae-bacteria membrane bioreactors. The setup, nutrient removal, TOC reduction, and microbial growth are analyzed, alongside the impact of microalgae on bacterial signaling and biofilm formation. Key findings reveal that microalgae reduce bacterial signaling capacity, leading to lower EPS production and improving system control. Conclusions cover aeration needs and effective growth management for algae and bacteria within these bioreactors.
