Water treatment
Chemical-free industrial water treatment · FIONER
Clean water, free of algae and scale, in large tanks and industrial circuits, with no biocides or additives.
Keeping water in condition used to be costly and demanded constant attention. With the ionic input of FIONER, developed by FRIMONT, water stays in condition with lower consumption, less blowdown and no chemicals to handle.

Applications
What it solves.
Water exposed to heat, air and nutrients grows algae, bacteria and biofilm; water that evaporates or heats up deposits carbonates. FIONER treats the water from the circulation pipe and regulates blowdown so the circuit runs at higher cycles of concentration.
- Large service water tanks and reservoirs.
- Open process cooling water circuits.
- Heat exchangers running on hard water.
- Cooling towers and evaporative condensers.
Configurations
A configuration tailored to your application.
Technical selection defines the equipment and its integration with the process.
Algae, fungi and biofilm
Eliminated in the water and wherever there is liquid water, once the required treatment intensity is reached. Without biofilm, bacteria lose the shelter biocides cannot reach.
Bacteria, viruses and Legionella
Full or partial elimination depending on the selected electrode. Helps prevent Legionella and other infections.
Carbonate scale
Prevents new deposits and slowly breaks down existing limescale, with no acid descaling treatments.
Water and effluent savings
With automatic blowdown and higher cycles of concentration, make-up water and effluent volume go down.
Safety and maintenance
No chemicals on site: no handling, no storage and no corrosion from chlorine or acids.
In operation
- Non-toxic and non-irritant to people.
- Not aggressive to metals.
- The dispenser needs no maintenance; the electrode kit is swapped on the spot.
- Only an acceptable pH, between 7 and 8, is required.
Technical data
Reference values.
Traditional chemical treatment and FIONER
| Aspect | Chemical treatment | FIONER |
|---|---|---|
| Biological control | Biocides dosed periodically; they do not reach bacteria sheltered in biofilm and under scale. | Continuous ionic input; eliminates biofilm wherever there is liquid water. |
| Scale | Anti-scalants and periodic acid cleaning. | Prevents new deposits and breaks down existing ones. |
| Consumables | Constant replenishment: part of the additives is lost with every blowdown. | No additives; only the electrode kit is replaced. |
| Metals | Chlorine and acids call for added corrosion inhibitors. | Not aggressive to metals. |
| Safety | Chemical handling and storage. | Non-toxic and non-irritant. |
| Blowdown | Manual or continuous. | Automatic, controlled by FIONER. |

Final selection depends on the equipment, the recirculation flow and the water analysis.




Selection
How we define the solution for your process.
We start from what you need to achieve and your facility conditions. We guide you through defining requirements and selecting an appropriate configuration. You do not need to have all this data to start the conversation.
What we evaluate during technical definition
- Annual use
- FIONER pays off when the circuit operates more than 3 months a year.
- Circuit and flow
- Water volume, recirculation flow and pipe diameter set the series and the dispenser length.
- Water quality
- Make-up water analysis, with no prior chemical treatment (softened water is fine), and pH between 7 and 8.
- Installation
- Power supply, control panel location (preferably indoors), level control and a blowdown discharge point.

Scope is defined with you.
From equipment selection to integration, installation, and commissioning, we agree on what the project needs and how it connects to your facility. Control systems and after-sales service are integral parts of that conversation.
