Abstract
The purpose of this research is to co-culture microalgae and yeast in secondary treated wastewater in a bioreactor. Wastewater will be characterized via measuring pH, turbidity, COD, ammonia, nitrate, orthophosphate, conductivity, and total suspended solids, before and after microalgae and yeast cultivation to monitor the efficiency of the wastewater treatment process. For harvesting biomass an ozonation/ozoflotation process will be used with the variation in the flow rate, ozonation time and ozone concentration to optimize the process. This research will empirically investigate the effect of cell disruption of microalgae using ozoflotation. Furthermore, the research aims to find the optimum harvesting approach by combining ozoflotation with other techniques. All the experiments will be done multiple times in order to achieve accurate results. This research aims to combine the separation of microalgae and harvesting of lipid in the same process to reduce the energy demand. Also, it aims to quantify the cell rupture of microalgae by ozonation.

| Description | My work focuses on using yeast to treat wastewater, which is an important area of research as wastewater can have harmful effects on the environment and human health if not treated properly. I have developed a model that can predict how much yeast biomass will be produced and how much carbon, nitrogen, and phosphorus will be consumed during treatment. This information can be beneficial for designing and optimising wastewater treatment systems. I have also developed a method for harvesting the yeast using induced air flotation, which is a process that can separate the yeast from the wastewater more efficiently than traditional methods. This can help reduce the cost and time required for yeast harvesting. In addition, I have prepared different biocomposites (yeast biocomposite, microalgae biocomposite and yeast and microalgae biocomposite). I have also investigated the performance of these biocomposites in treating wastewater and found that they can effectively remove pollutants from the wastewater. Overall, my work has contributed to developing a sustainable method for treating wastewater using yeast and microalgae. This research can potentially improve the quality of wastewater treatment. |
