Novel disinfection technology developed by Trustwater
I studied for my Bachelor’s Degree in the Trinity College Moyne Institute of Preventive Medicine, and moved and incredible distance of 10 metres to the Dublin Dental University Hospital for my PhD in applied and environmental microbiology.
My project looks at a novel disinfection technology developed by Trustwater, which is based in Clonmel, Co. Tipperary. The technology is based on the electro-chemical activation of water. An electric current is passed through a dilute salt solution in a flow-through electrolytic membrane and this allows for the generation of two oppositely charged solutions. Aversol, the catholyte is highly effective as a detergent and is especially suited to the food and drinks industries. Ecasol, the annolyte is a positively charged solution that is the basis of most of my research. It is a pH neutral solution composed mainly of hypochlorous acid which is known to kill microorganisms, in the same manner that white blood cells in our own bodies kill invading organisms with the oxidative-burst pathway.
One problem with other electro-chemically activated water systems is their capacity for material corrosion due to the solution having acidic pH and leaving behind salt residues. Ecasol is pH neutral and leaves behind 70% less salt than the next leading technology.
Other benefits of Trustwater’s technology are:
• Generated on site
• Replaces toxic chemicals
• Negligible packaging
• Minimal waste
• No disposal precautions
• Low carbon footprint
• No known resistance
We are looking at the ability of Ecasol to kill and remove biofilm from water systems in dental chair waterlines. This is important to prevent susceptible patients from becoming infected with water-borne bacteria such as Pseudomonas aeruginosa . I’m also looking at replacing other toxic disinfectants with Ecasol for use with dental alginate teeth impressions.
