Pulp and paper mills are among the largest industrial water consumers. They need water to ensure reliable, continuous operations. But at the same time, they’re being pressed to reduce their water footprints.
Innovative technologies and industry knowledge from DuPont Water Solutions can help solve water treatment challenges — from high-purity boiler makeup water treatment to fiber removal from the waste streams — thorough the entire pulp and paper production process.
Like in many processing plants, pulp and paper mills need to deal with challenging cooling tower water. If not properly filtered, cooling tower water can result in scaling, corrosion, and contamination that can adversely affect production.
Our industry-leading knowledge and local expertise in cooling water treatment can help you define a strategic solution that saves money, prevents problems, and helps better manage overall water resources.
Our solutions address:
Water-treatment needs for boiler feedwater in pulp and paper mills depend on the operating pressure and type of boiler. This can vary from simple soft water for low-pressure boilers to demineralized, or even polished, makeup water for high-pressure boilers and power turbines.
We provide a variety of applications to help lower costs and increase production, including ultrafiltration pretreatment, industrial softening demineralization, and the polishing of demineralized water or condensates.
Our solutions address:
An increase in global and local regulations means pulp and paper plants must become more environmentally responsible, particularly in the development of sustainable waste solutions and residuals management. It’s also a very water intensive, with plants facing increased pressure to reduce its water use.
We offer proven technologies that facilitate waste and process stream treatment to significantly reduce a facility’s water footprint.

Our technologies provide industry-leading, long-lasting, and cost-effective solutions. Learn more about the technologies relevant to the pulp and paper industry.
UF uses a membrane barrier to exclude colloids, bacteria, and more; for pretreatment in demineralization, industrial water production, drinking water production, or wastewater reuse.
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.
RO is a pressure-driven separation process that reduces the smallest of solute particles and treats most ions and large molecules in the water.
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.
