2 Silver Ionization: What are the benefits?
Silver has been used for centuries as a way to prevent or reduce bacterial growth. In ancient times cultures
discovered that water stored in silver pots had a longer useable life than other types of pots. Today silver
is used in a variety of bacteria-reducing & preservation applications from clothing to water purification.
The Electro Katadyn (EK) system uses electrical modulation of the catalytic process to introduce silver ions
into water flowing through the system. Based on Faraday’s law and system design, as parts per million
amount of silver ions are introduced into the water. At various concentrations, this ion-enriched water
preserves drinking water, is used for rinse and disinfection of food equipment, or in hot water systems to
prevent Legionella growth.
Silver ionization offers additional benefits in simplicity, maintenance and eco-friendly processes.
Compared to liquid or gas chemical treatment, ionization offers a much simpler process. Depending on
the application and volume required, the EK system can be piped into a bypass or direct line to deliver the
ions. It does not require separate chemical pumping, dose control and contact tanks to ensure safety. The
Electro-Katadyn system use of Silver anodes means operators aren’t constantly adding new chemical
mixtures to the process and reduces the chances of under- or overdosing the water in normal operation.
This reduces the complexity and logistics required to support the chemicals as well as any additional safety
protocol equipment.
The Katadyn EK silver ionization system is easy to maintain. Anode changes are simple mechanical
replacements requiring no electrical or special materials handling by site operators.
Katadyn anodes are a fraction of the volume of liquid or gas containers used by other treatment methods.
The small size of the anodes reduces the freight costs and carbon footprint, handling and packaging
required for operating the system. The overall system has a much smaller footprint also reducing the
associated capital costs for space for the client.
The EK 24 systems offer users two types of solutions:
Normal water treatment (conductivity > 100 µSiemens) for preservation, legionella or cleaning
applications are covered by the standard EK x-24 units.
Customers with low conductivity water (conductivity 10 to 100 µSiemens), typically marine or Food and
Beverage production, can benefit from the EK x-24 LC units.
