University of Illinois, Urbana-Champaign Has a New Answer for Seafood Demand
Did you know the U.S. imports more than 80 percent of its seafood? While aquaculture (fish farming) is increasing in popularity, domestic farmers find it hard to raise fish because treating waste can be an expensive and difficult process.
The University of Illinois at Urbana-Champaign created an economical and green way to treat wastewater using wood chips. Filtering water from a fish tank, the wood chips naturally remove nitrogen pollutants. Finding an effective and sustainable way to treat wastewater in aquaculture will encourage more produces to raise fish domestically, helping increase food security as the seafood momentum continues.
The woodchips are placed in a container called “bioreactors” – read more about how the system works here.
