Lawrence Livermore National Laboratory conducted an independent review of the Electro-dialysis process created by Zero Discharge Technologies and its effectiveness in reducing both chemical purchases and disposal costs.

Zero Discharge Technologies has re-posted a significant Case Study published by Lawrence Livermore National Laboratory on Electroless Nickel Recycling via Electro-Dialysis.

The study, originally published in 1995, has been re-posted to Zero Discharge Technologies’ new online home at http://www.zerodtech.com and is available for viewing and downloading.

Founded in 1983, Zero Discharge Technologies, Inc. provides diffusion dialysis systems for the recycling of contaminated acids. The company also has developed electro-dialysis systems for the purification of plating baths and other baths commonly used in electroplating.

The company’s customizable purification systems are capable of removing deleterious ions from solutions thereby allowing reuse of a “spent” bath. In addition to the ability to recycle the previously unusable bath the removed contaminant can usually be concentrated to significantly decrease waste removal costs. The processes result in a 90 percent reduction of water usage and chemical wastes, creating re-usable baths and significantly reducing disposal costs.

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

Electroless nickel is widely used in the metal finishing industry as a coating because it plates evenly one a wide variety of surfaces and replicates or enhances the surface finish. However, the bath life is limited and it has a tendency to spontaneously plate out on the tank and associated equipment.

Lawrence Livermore National Laboratory conducted an independent review of the Electro-dialysis process created by Zero Discharge Technologies and its effectiveness in reducing both chemical purchases and disposal costs.

Through testing and trials, the review proved that the Electro-dialysis process improved plating performance while also making it possible to use the bath many times over without the need for disposal.

The review concludes that the cost of the equipment is quickly recovered through the process. The review further states that adding nickel recycling to the plating process can save up to $495 per 100 gallons of process solution.

The study was further validated by the Environmental Protection Agency (EPA) which conducted a study of its own at Metco Metals in Arizona. The process reduced the metal finishing company’s annual new bath preparation from 71 down to three while reducing chemical costs by 25 percent.
The EPA study is also available through http://www.zerodtech.com.
