In June 2020, EDI integrated with Nexom after having been acquired by KKR and XPV Water Partners. This enables EDI to hold a much stronger position in the market with enhanced, synergistic capabilities and a wider range of solutions in our integrated portfolio of biological treatment and filtration technologies. Together with Nexom, our vision is for every drop of wastewater to meet the highest nutrient standards at the lowest possible energy footprint.
