Solvated Electron Destruct Units Are Creating a Paradigm Shift Towards Advanced Water Treatment and Purification
Despite the well-known improvements in conventional water treatment technologies over the last half-century, there still remain concerns about harmful effects of residual water treatment chemicals on human health.

Despite the well-known improvements in conventional water treatment technologies over the last half-century, there still remain concerns about harmful effects of residual water treatment chemicals on human health. This is one of the main reasons why non-chemical water treatment technologies are becoming increasingly popular. Some important non-chemical treatment technologies include carbon-fiber filtration, UV photocatalytic disinfection, and solvated free-electr;ons exposure.

In a recent paper co-authored by chemistry and water science professor Dr. Stephen Opoku-Duah, it was shown that coupled solvated free electrons (generated from low-energy UV radiation), and electron separation from porous cellulose fiber and glass particulate filtration (70µm) have strong capabilities in destroying harmful bacteria and pathogens from highly contaminated water sources including local rivers, creeks, ponds and storm-drainage systems.

"Alternative electro-chemistry free-electron-activated water purification systems represent a meaningful paradigm shift toward a unique advanced water treatment and purification approach. Electron-activated water purification can eliminate disease-causing bacteria by nearly 99.995%, and has enormous potential to deliver clean potable water to poor communities around the globe without recourse to chemical additives", said Opoku-Duah.

In this paper, Opoku-Duah et al. do not only show how electron-activated water treatment technologies can improve contaminated sources, but also show how capable alternative electro-chemistry systems can measure against standard parameters such as EPA water quality standards, municipal drinking water, and commercial bottled water. Also, the authors illustrate how simple, adaptable and affordable electron-activated water purification technologies can be, and the possibility for such innovative systems to deliver clean potable water to poor households in developing countries. Opoku-Duah goes on to add that "Field trials of their new water technology predict continuous delivery of clean drinkable water (with very minimal operational maintenance) to local communities at about $0.27 as against conventional water delivery systems, which on average cost $0.50 per person per day."
