5. 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
6. 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

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

8. “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”

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.

12. 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

13. 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
