Although Pseudomonas seldom infects healthy individuals it's a significant threat to those already suffering from a medical condition, particularly cystic fibrosis, AIDS and cancer. It's also very hard to eliminate. However, ProEconomy's copper and silver water treatment system is a proven method of Pseudomonas control for commercial sites, industrial buildings and cooling towers.

Pseudomonas Control With ProEconomy
Pseudomonas Control With Copper Silver IonisationOur Orca copper and silver ionisation system provides advanced Pseudomonas control for cooling towers and industrial and commercial sites across the UK and Europe. Unlike other water management systems, copper silver ionisation contains the following benefits:
- Is non-corrosive
- Has a proven residual effect
- Is fully compliant
- Is scientifically proven to work
- Creates no COSHH issues
- Is effective at high and low water temperatures
The Science Behind Pseudomonas Control With The OrcaResearching water treatment since 1993 has enabled us to build up ample data on Pseudomonas control methods and prove the efficacy of the Orca system with case studies and scientific reports. With a PhD in Legionella control, ProEconomy founder Dr Birgitta Bedford has researched and compiled a list of 40 scientific papers that support copper and silver ionisation for Pseudomonas control, some of which you can view here.
Lutz, J.K. & Lee, J., 2011.Prevalence and antimicrobial resistance of Pseudomonas aeruginosa in swimming pools and hot tubs. Int. J. Environ. Res. Public Health, 8, 554-564. "The temperature range in indoor recreational water is ideal for P. aeruginosa proliferation, which routinely grows in water 4-42 degrees Centigrade."
About PseudomonasPseudomonas is a water borne pathogen that typically infects those already suffering from a medical condition and is unfortunately regularly found in hospital water supplies.
Pseudomonas Monitoring With TetrasOur Tetras cloud based water management system uniquely combines our water sampling service and management software to provide you with real-time results that allow you to monitor Pseudomonas and control risk.
Health and Safety Executive, (2014) HSG274 Part 2: The control of bacteria in hot and cold water systems, para. 2, p.3“There is a reasonably foreseeable Legionella risk in your water system if:
- water is stored or recirculated as part of your system
- the water temperature in all or some part of the system may be between 20–45 °C;
- there are deposits that can support bacterial growth, such as rust, sludge, scale and organic matter;
- it is possible for water droplets to be produced and, if so, if they can be dispersed;
- it is likely that any of your employees, contractors, visitors etc. could be exposed to any contaminated water droplets.”
Scientific Evidence for Copper and Silver efficacy against Pseudomonas bacteria
- Field Studies
- Panzer et al. (2013) studied the isomorphic deactivation of a Pseudomonas aeruginosa oxidoreductase. They showed using X-ray crystallography that the silver ion binds to a key respiratory enzyme in P. aeruginosa, inactivating it. Link to abstract
- Fisher et al. (2009) studied the combined effect of copper and silver against Pseudomonas. Sterile cotton swabs impregnated with copper nitrate and silver nitrate solutions removed 100% of P. aeruginosa from a stainless-steel surface. There was no cross-contamination of other surfaces when the wipes were applied, suggesting that the microbes had been inactivated.
- Huang et al. (2008) studied the in-vitro efficacy of copper and silver ions in eradicating Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Acinetobacter baumanii. The three species of bacteria were exposed to a range of copper ion concentrations (0.1 - 0.8 mg/L), silver ions (0.01 - 0.08 mg/L), and combinations of both. All copper solutions achieved more than 99.99% reduction of P. aeruginosa. Silver at 0.04 - 0.08 mg/L achieved more than 99.99% reduction. The two together showed a synergistic effect. Link to paper
- Yahya et al. (1989) demonstrated complete inactivation of Pseudomonas aeruginosa, and a 2.4 log10 reduction within 2 minutes of Staphylococcus species, by 0.4 mg/L copper, 0.04 mg/L silver, and reduced levels of free chlorine (0.3 mg/L).
