Copper Silver Ionization FAQ

What should I consider when deciding between a copper silver ionization Point-of-Entry and a Domestic Hot Water application?

To determine whether you need a Point-of-Entry (POE) or Domestic Hot Water (DHW) application, answer the following questions:

  • Is your incoming facility water above 68°F (20°C)? 

  • Does your facility have low occupancy or the potential for water stagnation? 

  • Is the facility geographically located in the South (Southern USA, Central & South America, Southern Europe, Middle East, Asia)? 

  • Are there liability concerns that warrant treating all of the facility potable water?

If you answered “Yes” to any of these questions, then a POE should be considered. If “NO” is the answer to all of these questions, then a DHW application can be considered unless otherwise recommended by an industry professional.

How do I size a copper silver ionization system for a point of entry application for 100% incoming water treatment?

You will need to gather following information to properly size a copper silver ionization solution for your point of entry (POE) application. 

  • Size of the POE water line where you want the CSI solution installed,

  • Maximum water flow,

  • Location of the cooling towers makeup water line if present,

  • Expected daily water loads,

  • Determine if you want the CSI system installed “in-line” or “in-parallel” to the incoming water line.

Copper Silver Ionization FAQ

Is Copper Silver Ionization safe for humans consumption?

Copper silver ionization water treatment is safe for human consumption and does not pose health risks at WHO and/or EPA regulated potable water levels. Facility managers and building owners should periodically test their potable water for ions no less than once per week. Note that the EPA does not test or endorse commercial products, services, or businesses.

How long do Copper Silver Ionization Cells Last?

When properly sized and with regular preventative maintenance, a CSIDefender® Chamber Cell will last 12 to 18 months or longer. The alloy usage is directly proportional to the daily water usage.
Copper Silver Ionization FAQ

Where are copper silver ionization manufactured?

CSIDefender® and AquaLyse® copper silver ionization water treatment solutions, for Legionella growth control and prevention in facility potable water networks, are designed, manufactured and assembled in Canada. These particular units can be found globally yet all have Canada as country of origin without exception.
Copper Silver Ionization FAQ

How Does Copper Silver Ionization Penetrate Biofilm?

Biofilm is normally made from organic living matter, organic dead matter and inorganic materials. Biofilm is known to build-up over time inside a facility's potable water distribution network where it can protect and nourishes Legionella bacteria. This in turn can provide ideal growth environments that eventually become problematic for Legionella growth & exposure. CSIDefender® releases positively charged copper and silver ions which saturates this biofilm in 30 – 45 days, creating an environment where Legionella can no longer freely grow and can prevent future growth of this bacteria.
Copper Silver Ionization FAQ

What is Legionnaire’s disease?

Legionnaires’ Disease , originally identified in 1976, is a serious type of preventable pneumonia (i.e. lung infection) that happens when infected micro water droplets, containing Legionella bacteria, are unknowingly inhaled by an unsuspecting person who then might develop Legionnaires’ disease or the milder and less severe version known as Pontiac fever. Most people globally have been exposed to Legionella bacteria yet those who are more at risk of developing Legionnaires’ disease include: the sick, immune compromised, the elderly, smokers, athletes and others with health conditions. These demographics are predominantly found in healthcare facilities, long term care facilities, hotels, cruise ships, high-rise buildings and other types of facilities with elaborate potable water distribution networks.
Copper Silver Ionization FAQ

Why is preventing Legionella bacteria important?

Legionella bacteria, causes Legionnaires’ disease, is a severe and often lethal form of pneumonia. It can develop when a person inhales micro water particles contaminated with Legionella bacteria. Each year, an estimated 10,000 – 18,000 people are infected in the United States alone.
Copper Silver Ionization FAQ

Is Legionella bacteria strictly found in cooling towers?

People believe that most cases of Legionnaire's disease, cause by Legionella bacteria, are associated to HVAC and/or cooling towers. This is false. In fact, The WHO reports that cooling towers only accounted for 28% of global reported Legionnaires' disease cases. Other sources or Legionella contamination and Legionnaire's disease outbreaks include potable water outlets, hot tubs, domestic plumbing systems such as those hound in healthcare, hotels and long term care facilities.
Copper Silver Ionization FAQ

How are copper silver ions created?

CSIDefender® Ionization Chamber Cells contain medical grade electrodes which release positively charged copper and silver ions into the potable water distribution network. These ions bond with and neutralize Legionella bacteria, while saturating the biofilm where Legionella grows to prevent future growth. The result is a powerful and reliable solution that works across the entire water distribution system and keeps facility occupants safe from potential exposure.
Copper Silver Ionization FAQ

What preventative maintenance is required, and what are the effects if this is not performed?

Cleaning the ionization chamber cells is required every 3-6 weeks depending on water quality. Cleaning is very easy. Simply close the bypass, drain the chamber cell, remove the cell, clean & scrub, rinse and reinstall. A chamber cell maintenance activity can normally be done in less than 20 minutes. Chamber cell electrodes are consumables and will deplete over time. These should be replaced every 12-18 months depending on the water load and electrode depletion, to maintain performance.
Copper Silver Ionization FAQ

Do CSIDefender® Copper Silver Ionization Chamber Cells meet fire and plumbing construction codes?

Yes, unlike PVC and CPVC ionization chamber cells, CSIDefender® Ion Chamber Cells are housed in Schedule 40 (316) stainless steel external jackets. Not only does this provide increased durability, it also exceeds local fire building codes and plumbing water pressure and temperature codes.
Copper Silver Ionization FAQ

What happened is we don’t perform the monthly cleaning of the ionization chamber cells?

Failure to conduct preventative maintenance could damage the cell. CSIDefender® systems will detect the lack of maintenance and trigger fault alarms, eventually shutting down automatically until the cell is properly cleaned or replaced.
Copper Silver Ionization FAQ

How soon can we expect to detect ions after the CSI unit is started?

Depending on the size of the unit and number of cells, it can take between 5 – 40 minutes to fully saturate and maintain ionic concentrations in your potable water distribution network.
Copper Silver Ionization FAQ

How often should we test the water for ions once a CSI unit had been installed and calibrated?

Ongoing water testing should be conducted no less than once per week for technology validation.
Copper Silver Ionization FAQ

Can we install a smaller swimming pool CSI unit in a domestic potable water application and expect the same results as a commercial unit?

No. Smaller swimming pool type CSI units are not designed for facility potable water having larger daily water loads. Typically, these CSI units are physically much smaller, less alloy, do not adapt to varying water conditions, and have small electrodes, meaning they do not provide the performance or durability required for larger potable water distribution systems.
Copper Silver Ionization FAQ

Can we use copper silver ionization in drinking water?

Yes. City water treatment classified as primary and copper silver ionization is classified as secondary water treatment. When installed at a facility point of use, copper silver ionization can be safely utilised to provide Legionella growth prevention by following EPA drinking water guidelines. CSI technology compliments the initial “primary” city water treatment since city water known to not provide Legionella growth protection for larger facility water distribution networks.
Copper Silver Ionization FAQ

Where can I find Legionella growth control recommendations or standards?

Yes, there are a wide range of Legionella growth control standards available online. These include but not limited to: L8 Code of Practice (UK), ASHRAE188 (USA), WHO, CDC (USA), EPA (USA), JCAHO 1.7 (USA), CSA (Canada), CMS (USA), Health Canada, and many more.
