Creating re-usable baths & significantly reducing disposal costs by up to 90%

See How Much You Can Save with Zero Discharge

What We Can Do For You…

Zero Discharge Technologies, Inc. provides diffusion dialysis systems for the recycling of large volumes of contaminated acids.

The company’s customizable purification systems recover spent contaminated acid. The process results in up to 90 percent percent reduction of acid usage and chemical wastes, creating re-usable baths and significantly reducing disposal costs by up to 90 percent.

These innovative systems increase both process quality and profitability while simultaneously moving the plating and manufacturing industry toward environmentally sustainable business practices.

Zero Discharge Technologies’ systems are currently in use internationally with systems operating in China, Taiwan, England, India, and the United States.

Electrodialysis Equipment

Electrodialysis is electrically driven ion-exchange utilizing alternating sequences of cation membranes and anion membranes. Conventional ion-exchange techniques involve the “adsorptive exchange” of an ion in a solution with an ion attached to the functional group of the resin head.

Application:
• Desalination of closed-loop process water
• Recovery of metal salts
• Potable water production

Benefits:
• Maintenance of high-quality process water
• Recovery of valuable resources
• Reduced waste treatment and waste disposal
• No regeneration required

Donnan/Diffusion Dialysis

Donnan/diffusion dialysis is a little known alternative to conventional ion exchange techniques. Using perm-selective ion exchange membranes specific cations or anions can be targeted for removal and concentration.

Application:
• De ionization of closed-loop process water
• Recovery of metals from low concentration
• Non additive pH adjustments
• Separation of monovalent ions from multivalent ions

Benefits:
• Maintenance of high quality process water
• Recovery of valuable resources
• Reduced waste treatment and waste disposal
• No resin regeneration required
• Generate desired cation/anion complexes
