Copper and silver ionisation

Copper and silver ionization is a method used to control and combat Legionella and other bacteria in drinking water systems. This unique technique is particularly effective in locations such as hospitals, healthcare facilities, hotels, swimming pools, and saunas.

Unique water management technology

In the early 2000s, Holland Water introduced the copper and silver ionization method to the Netherlands. Holland Water's founder, Leo de Zeeuw, and technical expert Wiebe Pool, developed a brilliant idea for the precise dosing of copper and silver ions. This concept was so innovative and effective that it has since been patented. As a result, 20 years ago, a revolutionary new application of the method was born to make and keep water systems free of Legionella: the HW Bifipro® for drinking water systems.

Highly effective against Legionella and biofilm

Copper and silver ionization is highly effective against Legionella and other bacteria, providing continuous protection. It is a sustainable and cost-effective solution, unlike the use of environmentally harmful chemicals.

What is it?
  • Copper and silver ionization technology
  • Kills Legionella bacteria and removes biofilm
  • Safe for humans, animals, and the environment
  • Compliant with strict (drinking) water regulations

How does copper and silver ionisation work?

Copper ions

Accumulated copper ions play a key role in deactivating and eroding biofilm over time, which is the primary breeding ground for Legionella bacteria and the source of widespread colonization. Copper is crucial for ensuring the long-term effectiveness of biocide application and Legionella control.

Silver ions

Silver ions are especially effective in the early stages by directly killing free-floating Legionella bacteria. The symbiotic interaction between copper and silver also plays a significant role in this process.

Access to safe drinking water

Water has become a scarce resource, we believe that everyone should have access to safe drinking water. We offer technology-driven water management in a smarter, safer, cost-effective, and sustainable manner. With the HW Bifipro®, water can be consumed straight from the tap, eliminating the need for bottled water and reducing plastic pollution and waste. A less intensive flushing regime and a lower hot water temperature decrease water and gas consumption.
