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.

本研究的目的是在生物反应器中将微藻和酵母菌在二级处理废水中共培养。在微藻和酵母培养前后，将通过测量pH值、浊度、COD、氨、硝酸盐、正磷酸盐、电导率和总悬浮固体来表征废水，以监测废水处理过程的效率。为了收获生物质，将使用臭氧化/臭氧浮选工艺，通过改变流速、臭氧化时间和臭氧浓度来优化该工艺。本研究将实证研究臭氧浮选法对微藻细胞破碎的影响。此外，本研究旨在通过臭氧浮选与其他技术相结合，找到最佳的收获方法。所有的实验都将进行多次，以获得准确的结果。本研究旨在将微藻的分离和油脂的收获联合收割机结合在同一个过程中，以降低能量需求。此外，它的目的是量化臭氧氧化的微藻细胞破裂。
