The Orca copper and silver ions penetrate biofilm. This can initially cause an increase in total viable and Legionella bacteria counts due to the bacteria becoming freely suspended in the water since it is being released from the biofilm. But, because bacteria in biofilm proliferate to high numbers and colonise complete water systems from it, it is important that treatment to control Legionella, also, includes biofilm control.
The Orca system is the only system that is proven to attack and remove biofilm.
