We help customers make significant advancements by continuously innovating in the water filtration and purification technologies that form the core of DuPont Water Solutions.
RO is a pressure-driven separation process that reduces the smallest of solute particles and treats most ions and large molecules in the water.
NF is a pressure-driven separation process positioned between reverse osmosis and ultrafiltration used to treat color and pesticides, and to partially soften the water.
UF uses a membrane barrier to exclude colloids, bacteria, and more; for pretreatment in demineralization, industrial water production, drinking water production, or wastewater reuse.
IX uses polymeric resins capable of exchanging ions; applications include softening, bulk demineralization, trace contaminants removal, and condensate water polishing.
EDI is used as a polisher for boiler and ultrapure water makeup and can deliver the lowest conductivities, sodium, and silica in the product without chemical regeneration.
