Use of Biocidal Silver to Disinfect Recirculated Water

This research focuses on an innovative materials technology that allows the entrapment of biocidal organic compounds in biocidal silver resulting in the formation of a powerful antibacterial composite called SilverPlus. These silver composites perform better than  silver alone and their material properties ensure that they be used for disinfecting closed loop re- circulating water systems and to obtain drinking water during emergencies.

The research is of interest to fields such as environmental, cleantech and water technologies. The prototype for this research has been completed and PCT patent application has been filed.

Innovation

A device prototype that will help disinfect a recirculating water system has been developed utilizing a novel biocidal silver composite.

Key Features

The key features of this technology include the following:

• Novel antibacterial compositions based on normally used active substances
• Controlled release of the organic biocidal agents that are entrapped in silver
• Synergetic microbiocidal activity
• Minimized environmental fingerprints and burdens
• Residual disinfection abilities in the treated water systems

Applications

This technology has potential applications in the following:

• Industrial hot and cold water systems
• Hospital hot water systems
• Aquaculture
• Swimming pools

Current Status

Currently, opportunities are being sought to enable funding and commercialization of the technique to enable continued research and development.
