WEST LAFAYETTE, Ind. โ€” Aquaculture production operations that help feed the worldโ€™s growing population also generate polluted wastewater that harms the environment. Four studies published by Purdue University scientists since last May document the feasibility of previously unproven methods for successfully treating the wastewater.

โ€œThose wastewaters are not good for the environment because they discharge a large amount of nutrients like nitrogen and phosphorus,โ€ said Jen-Yi Huang, associate professor of food science. These nutrients cause harmful conditions such as oxygen depletion and algae blooms when they are discharged into the aquatic environment.ย We want to use microalgae as a wastewater treatment approach. We grow algae in the aquaculture wastewater,โ€ said Huang, who led a study focusing on microbial use of nutrients as a biological wastewater treatment method.

Huangโ€™s study appeared in the May 2024 issue of Bioresource Technology. Halis Simsek, assistant professor of agricultural and biological engineering, led the other three studies. One will be published June 1 in Environmental Research, and the others were published in the March 15, 2024, and Aug. 15, 2023, issues of Environmental Pollution.
