Greenwater Services is a U.S.-based water technology company headquartered in Brookfield, Ohio, specializing in water remediation through patented NanoBubble Ozone Technology (NBOT). Its chemical-free systems use ozone-infused nanobubbles and advanced oxidation to reduce harmful algae, bacteria, microcystins, nitrates, phosphates and other contaminants while increasing dissolved oxygen. The company provides portable and permanent treatment systems, ozone generators, diffusers, monitoring equipment and customized implementation services. Its technology supports municipal water, agriculture, industrial wastewater, data centers and government-led environmental projects across the United States, combining sustainable treatment with research-backed water quality improvement.
Field deployment of ozone-based treatment in a transboundary river achieved measurable microbial reduction, informing scaled water treatment strategies for U.S. restoration projects.
