The economic factor of the microalgae harvesting step acts as a barrier to scaling up
microalgae-based technology designed for wastewater treatment. In view of that, this study
presents an alternative microalgae-bacteria system, which is proposed for eliminating the
economic obstacle. Instead of the microalgae-bacteria (activated algae) flocs, the study
aimed to develop activated algae granules comprising the microalgae Chlorella sp. as a
target species. The presence of the filamentous microalgae (Phormidium sp.) was necessary …
