Limescale treatment technologies in water

You notice the presence of limescale and scale on your taps, mixers, and shower walls, which means your water is hard!

Hard water, characterized by a high concentration of calcium and magnesium, can lead to the formation of limescale deposits in plumbing systems and household appliances. To address this issue, several limescale treatment technologies in water have emerged, each with its own advantages and disadvantages. In this article, we will examine three popular approaches: salt and resin softeners, CO2 softeners, and the galvanic principle by anode.

Salt and resin softeners

Salt and resin softeners are among the most widespread solutions to combat limescale in water. The operation of these devices is based on ion exchange where the calcium and magnesium ions responsible for hardening the water are replaced by sodium ions.

Advantages:

High efficiency in reducing limescale.
Improvement of water quality for household tasks.
Extended lifespan of household appliances and pipes.

Disadvantages:

Use of salt, which can increase the sodium content of the water.
Need to periodically regenerate the resin with salt.
Environmental impact related to the disposal of salt used in the regeneration process.

CO2 Softeners

CO2 softeners take a different approach by injecting carbon dioxide into hard water. This method causes a chemical reaction that transforms calcium ions into calcium carbonate particles, which do not form deposits.

Advantages:

Reduction of limescale without adding salt.
No need for regular regeneration.
Reduced environmental footprint compared to salt softeners.

Disadvantages:

Higher initial cost.
Less effective in very hard water.
Requires a source of carbon dioxide.

Well suited for collective housing

From small co-ownerships to buildings with hundreds of units, the CO2 softening process adapts to all sizes of buildings. It is sized according to water flow rates. It is easy to install and requires little maintenance. Costs and maintenance cycles are greatly reduced (showers, toilets, sinks, …).

Galvanic Principle by Anode

This technology is based on the principle of galvanization, using a zinc alloy anode to release zinc ions into the water. These ions react with calcium and magnesium, preventing them from depositing as limescale.

Advantages:

No need for chemicals or salt.
Low maintenance cost.
Environmentally friendly.

Disadvantages:

Reduced efficiency in very hard water.
Requires professional installation.
May require regular monitoring to ensure optimal operation.

The Importance of Hiring an Experienced Professional

The choice of limescale treatment technology depends on various factors, such as local water hardness, environmental concerns, and budget. Salt and resin softeners remain the most common solution, while CO2 softeners and the galvanic principle by anode offer environmentally friendly alternatives. It is crucial to carefully consider the advantages and disadvantages of each option to make the best decision based on individual needs.
