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.
Membrane degasification reliably removes dissolved gases from water to prevent oxidation and reduce ionic load on downstream processing equipment.
