United Expertise

With the goal of creating a single group with a common vision, three H2O Innovation business lines, PWT™, Genesys®, and Piedmont came together in July 2022 to form a unique H2O Innovation business line dedicated to chemicals, components, and consumables. Whereas Genesys and PWT develop and manufacture specialty reverse osmosis (RO) membrane chemicals, antiscalants, cleaners, flocculants, and biocides, Piedmont is a global leader in corrosion resistant equipment for desalination plants. With a complete line of RO pretreatment and maintenance products, comprehensive analytical and technical capabilities, and a progressive research and development group, we offer solutions to maximize system performance. Our market-leading products and equipment are distributed by a growing network of international distributors, selected for their expertise in the chemical and membrane industries.
