Silver's antimicrobial effect isn't new, it's been understood for hundreds of years. What's new is dosing it electronically, at a precise and constant low level, straight into the water flow. No chemicals are added, stored, or topped up.
Every Silverflow Technology system, regardless of size, works on the same underlying mechanism.
Low-voltage pulsed direct current passes across high-purity (99.99%) silver anodes, releasing microclusters of silver colloids directly into the water flow.
Electronically controlled dosing keeps concentration constant, calibrated to 20–50 μg/L, well within WHO and Australian Drinking Water Guidelines (100 μg/L).
Positively charged silver colloids bind to thiol groups in bacterial cell walls, disrupting membrane transport and stopping replication.
Unlike chlorine, silver colloids don't off-gas or evaporate. That "depot effect" keeps static water and low-flow lines protected for up to 180 days.
Silver colloids need contact time to penetrate a bacterial cell wall. That makes it fundamentally suited to static storage, overnight stagnation, and low-flow systems, rather than high-flow environments like cooling towers that need an instant kill.
In hard water, mineral scale can build up on any electrode over time. Silverflow Technology's controller firmware automatically reverses polarity every 120 minutes, shedding that buildup before it becomes a problem, without any manual descaling.
High suspended solids in raw water can absorb active silver colloids before they reach the bacteria. A standard 5-micron sediment pre-filter on the incoming supply line is the only preparation required.
A system that needs constant topping up or monitoring isn't really solving the problem. Silverflow Technology is designed to keep working quietly in the background.
Silver colloids don't evaporate or degrade in warm temperatures, unlike chlorine, which loses effectiveness within days.
Operates well below drinking water safety limits, with none of the chemical taste that comes with chlorine or peroxide flushes.
Completely inert on polyurethane tubing, rubber seals, copper, brass, and fibreglass, so fittings last longer.
Ultra-low power draw makes every model solar and battery-compatible where mains power isn't practical.
The most common concern raised about silver-based systems, addressed directly.
Yes. Silverflow Technology systems are hard-calibrated to 20–50 μg/L, less than half the WHO and Australian Drinking Water Guidelines safety ceiling of 100 μg/L. Independent lab testing confirms dosing stays within this range at all times.
Argyria is associated with prolonged, very high-dose silver exposure, orders of magnitude above drinking water levels. At the micro-doses Silverflow Technology uses, this isn't a realistic risk, and it's the reason every system ships with lab certification.
No. At these concentrations, silver is imperceptible to taste, which is part of why it suits environments like dental practices and food production where chemical taste is a genuine problem.
The controller's automatic polarity reversal handles mineral scale build-up on its own, every two hours, so hard water doesn't require any extra maintenance step from you.
The mechanism is the same everywhere, but what it solves looks different in a dental chair versus a cooling tower.
