ABSTRACT
This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book focuses on the use of microalgal-bacterial consortia for nitrogen removal. It assesses the removal mechanisms in microalgal-bacterial consortia using synthetic wastewater under different operational conditions in two types of photobioreactors. These two types are: circular and flat panel reactor. The book assesses the microalgal-bacterial consortia using real wastewater. It presents the calibration and validation of a mathematical model that describes the microbiological processes occurring between aerobic oxidising bacteria, nitrite oxidising bacteria, heterotrophic bacteria and microalgae. The book describes the use of respirometric tests for microalgal-bacterial biomass showed the fate of the nitrogen taken up by microalgae and its effects on the nitrification. It demonstrates that microalgal-bacterial consortia removed ammonium 50% times faster than in a solely microalgal system, which ultimately increases the efficiency of the system.
