We are the first ionization company to obtain NSF/Ansi 61 Certification!
Enrich Products Inc., was the first ionization company to begin using??short-term, or as we refer to them, “Short??Course” treatments. ??We introduced this application in 2007 as a response to the need expressed by our health care client to have a solution ( to a Legionella outbreak) immediately without incurring a large cost. ??Their primary need was for immediate results however, they were also concerned with seeing its efficacy before committing to a long term program.
Our??Short??Course??method requires diligent??monitoring, can significantly reduce Legionella in water quickly,??and copper silver levels needed for Legionella control can be achieved within hours.
Enrich Products has been a leader in Legionella control for over 17 years and is our systems are EPA registered. Our dedicated staff work as partners with facilities to control Legionella using the Best Available Technology, and can deliver an emergency??Short??Course??system within 24 hours.

Abstract ??? Copper/silver ionization is a new disinfection method that is being used to eradicate Legionella pneumophila from the hospital hot water recirculating systems.?? The objective of this study was to determine the susceptibility of L. pneumophila serogroup 1 to copper and silver ions alone and in combination.?? L. pneumophila serogroup 1 (L.p. sg- 1) was completely inactivated (6-log reduction) at copper concentrations of 1 mg/l within 2.5 h, whereas more than 24 h was required to achieve a similar reduction at the highest silver ion concentration tested (0.08 mg/l).?? Checkerboard method and Gard additive model prediction demonstrated that copper and silver ions in combination could result in additive or synergistic effect depending on the concentration of copper and silver ions.?? Under the experimental conditions used in this study, synergism of copper/silver ions in eradicating L.p.sg-1 was observed at higher concentration combinations of copper/silver ions (e.g. 0.4/0.04 mg/l) while only an additive effect was observed at lower concentrations combinations (e.g. 0.2/0.02 mg/l).?? This study suggested that both copper and silver ions are effective in inactivating L. pneumophila and the combined effect is greater than that seen with either ion alone.??
