Aquatic animals can help purify our wastewater, says researcher

Aquatic creatures may help purify our wastewater. A team of researchers has investigated how invertebrates, such as worms, non-biting midge larvae and mussels that live on the bottom of streams and ditches, may benefit wastewater treatment plants. These creatures can degrade sludge, reduce greenhouse gas emissions, and remove excess nutrients from the water together with floating plant species.
