What is Copper Silver Ionization?
Process that introduces (+) charged copper and silver ions into a water system
Ions bond with ( - ) sites on bacterial cell walls and denature proteins
Long term, ionization disperses and destroys biofilms and slimes that harbor Legionella
5
Benefits of Copper Silver Ionization
Ability to penetrate the biofilm on pipe walls Eradicates Legionella in both hot and cold water Copper Silver Ions have a larger residual effect
than most other disinfectants Efficacy does not depend on water
temperature Low consumables cost compared to other
disinfection modalities Non-corrosive

Components: Flow Cell
The flow cell chamber houses the copper silver alloy electrodes which release ions into the domestic water supply

“Potable water is the most common source of healthcare-associated legionellosis…it was not
until a copper silver Ionization system was installed that we saw a decline in Legionella
numbers”-John Marx, MPH, Lead Infection Preventionist & Microbiologist

Copper Silver Ionization: How It Works
COPPER ION
SILVER ION
BACTERIA
The copper and silver ions disinfect synergistically. The positively charged copper ion will bond to the negative cell wall of the waterborne bacteria. The silver ion will the deconstruct the DNA of the bacteria causing cell death.

Target Copper Silver Levels
11
Components: Microprocessor Controller
The POWER SOURCE to the flow cell
Controls the release of the copper and silver ions
“Closed Loop Proportional Control” allowing the system to adjust itself based on water usage to ensure no over or under ionization
12
Components: Ultrasonic Flow Meter
The ultrasonic flow meter communicates the flow rate to the microprocessor controller
Allows for the system to dose copper silver ions based on water demand at any given time achieving “closed loop proportional control” which is unique to the LiquiTech system

Remote Engineer Monitoring System (REMS) Provides an outlet for continuous monitoring and trending of system
performance Remote communication & control to LiquiTech’s Engineering team Instant alarm notifications to facilitate immediate response via the
internet
