Microalgae to treat aquaculture wastewater

Researchers at Purdue University have demonstrated new, environmentally sustainable methods for treating aquaculture wastewater, as documented in four studies. The team, led by Jen-Yi Huang and Halis Simsek, explored the use of microalgae Chlorella vulgaris to treat nutrient-rich wastewater from aquaculture systems. Their research proves that microalgae can effectively recover nutrients and reduce environmental impacts compared to traditional treatments. Findings suggest that integrating microalgae treatments could significantly enhance the sustainability of aquaculture operations by minimising nutrient discharge and supporting zero-waste production goals.
