Wastewater reprocessing startup ZwitterCo announced on Thursday that it has raised $33 million to scale up its chemically engineered membrane water filtration technology to help industrial companies and large farms recycle wastewater.
The round was led by DCVC with participation from new investors Heritage Group Ventures, Genoa Ventures, and Mott Corporation, and existing investors MANN+HUMMEL Corporate Ventures, Burnt Island Ventures, and R-Cubed Capital Partners.
The patented filtration technology came out of a research lab at Tufts University.
In many cases — such as in manure digestate treatment, meat and poultry treatment, dairy waste water, and bioprocessing applications — the material that is filtered out with can be resold as fertilizer or feedstocks.
