Water Treatment with Copper & Silver
How does it work?

Copper silver ionisation is a water treatment method that removes bacteria based on the purifying effect of copper and silver ions. These ions control growth and disarm harmful bacteria in drinking water installations, such as Pseudomonas, Legionella, and E. coli.
The 3 step water treatment process of copper silver ionisation is described below.

Copper and silver electrodes can be purchased at ATECA. ATECA is the only Dutch supplier admitted to the ECHA article 95 list. Meaning, that we are permitted to supply copper and silver for both drinking and process water. Therefore, we can offer a guaranteed delivery of electrodes. The electrode costs depend on water consumption and contamination size. On average the electrode costs are €0.10 per m3 of water.

How long do the Cu/Ag electrodes last with proper preventative maintenance?2018-09-18T09:52:30+00:00

The Ag electrodes need to be replaced after every 10,000 m3 of water. The Cu electrodes need to be replaced after every 3,500 m3 of water. (This depends on the concentration settings)

How often should we test the water for copper, silver, Legionella and other microbiological activities?2018-09-18T09:47:26+00:00

We advise to test the water at least once half a year on the most vulnerable tappoints.

Is the ICA system certified?2018-09-18T09:26:11+00:00

The ICA system meets all strict requirements for an electrochemical management (copper silver ionisation) system. This means that the ICA system is KIWA certified on the basis of BRL K14010-1/2. A condition for obtaining this certificate is that the system has a KIWA ATA approval and an admission to the Ctgb. According to the Ctgb permit and the KIWA certification, the ICA system meets all requirements and the system is safe for people and the environment and effective in Legionella control and prevention. Additionally, ATECA obtained governmental concession of several countries to allow the use of the ICA system as a Legionella prevention and control installation.

Is the ICA system under warranty?2018-09-18T09:24:40+00:00

On the entire ICA system and all its parts, a guarantee applies after installation. The warranty period depends on the type of ICA system and on the agreement made before purchase. In the event of damage caused by third parties, ATECA is entitled to charge the restoration and repair costs to the client.

Where is the ICA system manufactured and how long does it take?2018-09-18T10:49:56+00:00

The ICA system is built in the ATECA workshop, completely customized for your location. Normally, we send the ICA system within four weeks after the order. In exceptional circumstances, we can prioritize projects.

The ICA ServiceLink continuously monitors the operations of the ICA system. With this platform, you can always access online logbooks, water analyses, and service reports. Additionally, you can watch live how the system is operating and settings can be adjusted if necessary.

How much does the ICA system cost?2018-09-18T09:19:17+00:00

Based on a location scan we design and build a customized ICA system, specifically adjusted to your location. This will determine the price of the system and installation. Although copper silver ionisation systems sound like a big investment, our customers always seem to be positively surprised after receiving a quotation. As one of our slogans state: “we believe in clean and safe water for everyone”. Hence, feel free to contact us for a price offer, we hope we can surprise you too.

Is the ICA system susceptible for warm water temperature and corrosion?2018-09-18T09:17:10+00:00

No, the ICA system is not susceptible for warm water temperature and is effective at all temperatures. Also, copper silver ionisation is non-corrosive for your pipework.

How long does it take to eliminate the Legionella bacteria after installment?2018-09-18T09:15:35+00:00

The ICA system is Legionella safe within 0-6 months.This depends upon the location and the situation (water quality, biofilm, management, material piping, Legionella problem etc.).

Do I need to perform a chemical shock before installing the ICA system?2018-09-18T09:13:52+00:00

This is certainly not compulsory and we know that it is sometimes unachievable (organisational wise). However, depending on the location and the size of the Legionella contamination, it could be desirable. The advantage of a chemical shock is that the ICA system can be installed in a “clean” situation. This Legionella safe situation will also be achieved without a prior chemical shock, it just takes slightly longer.

How soon can we expect to detect ions after installation of the ICA system?2018-09-18T09:12:04+00:00

As soon as the ICA system is operationalized, ion concentrations can be found in the water. You can accelerate the process by extensive flushing.

Is the ICA system safe for humans and the environment?2018-09-18T09:11:02+00:00

Yes, the ICA system and its technology have been extensively researched by the Ctgb and KIWA and comply with all strict protocols. Conclusion: it is not bad for your health nor for the environment. The active substances in these concentrations can not be absorbed by the human body. Additionally, all materials used in manufacturing are completely safe and environmentally conscious.

Does copper silver ionisation leave grey residue behind?2019-09-06T10:24:10+00:00

It is true that copper silver ionisation can leave a greyish residue behind in sanitary facilities. However, this occurs only at 10% of the locations, primarily in old and damaged plumbing. Besides, it is not dirty or unhygienic, it is a natural reaction of quicklime, silver ions and oxygen. Once the location is Legionella safe, the silver concentrations can be reduced which ultimately decreases the greyish residue. Furthermore, the greyish residue is easy to clean and not permanent.

How do copper and silver ions prevent Legionella bacterial growth?2020-11-04T09:26:06+00:00

The copper and silver ions have a synergistic effect to disarm the bacteria, stop growth, and obstruct biofilm production. This is done in three ways, which are illustrated on the right: a) attack the cell membrane, b) distort the proteins, and c) disrupt the reproductive system.

How are the copper and silver ions created?2020-11-04T09:26:57+00:00

The copper and silver ions are synthesised from very high purity Ag, and separate very high purity Cu electrodes. An electric potential creates a small concentration of ions in the drinking water. These ions are carried through the water and will do their work further down the entire drinking water installation.

Does the ICA system penetrate biofilm and why is this important for Legionella prevention?2019-09-06T10:17:25+00:00

Biofilm is a slimy layer of microorganisms that is attached to the pipework. It is a breeding ground for Legionella. Due to the constant presence of copper and silver, the ions penetrate the biofilm. As a result, the biofilm will dissolve and the Legionella bacteria will die.

When can we speak of a Legionella contamination?2019-09-06T10:15:01+00:00

The Legionella bacteria becomes a problem when it start multiplying. We can speak of a Legionella contamination when more than 100 cfu/L Legionella is detected in the drinking water installation.

Where can we find the Legionella bacteria?2019-09-06T10:14:04+00:00

The Legionella bacteria naturally occurs in soil and in freshwater, usually in low numbers. However, the Legionella bacteria can grow very fast in water, especially if it is stagnant water between 25°C and 45°C.

Why is Legionella prevention important?2019-09-06T10:13:25+00:00

The Legionella bacteria poses a serious threat to many businesses and institutions. Legionella (pneumophila) is a bacterium that causes Legionnaires’ disease or the Legionella flu, a dangerous and sometimes even deadly form of pneumonia. Infection with the disease may occur when people inhale small water droplets or aerosols containing the bacteria. Shower, sprinklers, hot tubs and similar water installations form a particular risk. Choking in contaminated water can also lead to infection; by which the contaminated drinking water can end up in your lungs.
