ZwitterCo

ZwitterCo is a water technology company offering solutions for industrial wastewater treatment and reuse. The company’s solution, called “Zwitterionic” membranes, is a rugged polymer membrane made from patented copolymers used for wastewater separation. Zwitterionic membranes are used to recycle tough-to-treat wastewater such as treating digestates, leachates, O&G (oil and gas) produced water, poultry and dairy, bioprocessing, and food and beverage produced wastewaters. The company claims to offer the world's first organic fouling-immune brackish water membranes, reducing cleaning frequency by up to 90%.

Its membranes are also stated to be immune to fouling after every wastewater cleaning cycle compared to traditional membranes whose performance degrades after each cleaning cycle. The company also claims that the material filtered out of the membranes can also be resold as fertilizer or feedstock.

In November 2023, the company initiated its Early Access Program for its new brackish water reverse osmosis (BWRO) membranes, allowing ZwitterCo to collaborate with select customers and OEMs for field applications ahead of the product’s commercial launch in 2024.

Key customers and partnerships

In October 2022, the company partnered with Digested Organics, a Michigan-based wastewater filtration solutions company, as a channel partner in North America to provide solutions for the digestate market. In May 2023, the company partnered with Mott Corporation to deliver wastewater solutions for manure and food-waste digesters, as well as breweries and distilleries, in North America.

Funding and financials

In September 2022, the company raised USD 33 million in Series A funding led by DCVC. The funds were to be used to expand the production and development of Zwitterionic membrane technology and support the construction of the company’s innovation center in Boston.
