Ion Exchange

Innovative ion exchange technology and rich industry knowledge from DuPont Water Solutions can help solve high-purity boiler makeup and fiber removal challenges throughout the entire pulp and paper production process. Consider Amberlite resins for industrial softening, demineralization, makeup water polishing, condensate polishin, fiber removal, metal removal and more.

Reverse Osmosis

Filmtec RO technology provides an industry-leading, high performance, reliable, and cost-effective solution for pulp & paper applications.


Nanofiltration elements in the pulp and paper industry is key to supporting sustainable production through effective water treatment and wastewater reuse. Invest in Filmtec NF elements for suspended solids removal, soluble contaminant removal, organics removal (BOD/COD/TOC), or reuse-water corrosion control.


EDI technology is a smart alternative to, and effective replacement of, conventional mixed bed ion exchange. And since electricity is EDI’s only consumable, this method of permeate polishing does not produce a hazardous waste stream, allowing power plants to produce continous high purity water while saving time, money, and space. DuPont EDI-210 and EDI-310 ion exchange modules contain a gaussian, gel, strong base anion exchange resin for industrial demineralization.

Case Study

Nanofiltration Produces Sparkling Clean Water for Swedish Resort Community
Lofsdalen, Sweden, had an outdated water treatment process complicated by variable water quality from an unreliable source. Using FilmTec™ NF255-400 membranes, the town could pull water from Lake Lofssjön, remove the contaminants, and provide sparking clean drinking water to the town residents and tourists.
FilmTec™ NF270-400 Element Helps National Park Service Improve Water Quality
The Denver Service Center of the U.S. National Parks struggled to treat tricky water that needed to meet EPA secondary Standards. Check out the full article to see the raw water constitutes, met requirements, and reduced operational cost.
