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.
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.
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.
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Lofsdalen, Sweden, had an outdated water treatment process complicated by variable water quality from an unreliable source.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.
