Limescale is a natural component of our water. Although it is not harmful to health, its unpleasant taste and smell can make using mains water unpleasant. What’s more, limescale can build up in our mains equipment, impairing its operation and reducing its lifespan. The only solution to this problem is anti-limescale filtration.
Limescale, a natural component of water with two facets
Limescale is a mineral naturally present in water, formed by the dissolution of calcium carbonate. It affects water’s ability to dissolve other substances. Limescale is not harmful to health; on the contrary, it provides the body with essential elements such as calcium and magnesium. However, it can have undesirable effects on the taste and smell of water, as well as on the operation of household appliances, pipes and taps. This is because limescale deposits in the form of scale, which reduces the flow of water, increases energy consumption and promotes corrosion. To avoid these problems, there are anti-limescale filtration solutions that reduce the limescale content of water and improve its quality.
Anti-scale filtration, a complete process for greater efficiency
To combat the harmful effects of limescale in water, there are anti-limescale filtration systems that treat the water at source, i.e. at the water cooler’s main inlet. These systems consist of several filtration stages, ensuring that the water is soft, pure and pleasant to drink. Here are the main stages in anti-limescale filtration:
- Pre-filtration to retain the thickest particles and dirt that may be present in the water, such as sand, rust or algae. This is done using a fibre or polypropylene filter with a filtration capacity of 5 to 50 microns.
- Second pre-filtration, this time with activated carbon, to adsorb organic substances and impurities present in the water, such as chlorine, pesticides or heavy metals. It also reduces water hardness by capturing some of the limescale.
- Passage through an ion exchange resin: in the case of anti-limescale filtration, the resin exchanges the calcium and magnesium ions, responsible for scale formation, with sodium ions, which have no scaling effect, softening and purifying the water
- 2nd treatment with activated carbon to improve the taste of the water and guarantee a neutral taste. This stage eliminates any sodium or polyphosphate residues that could alter the taste of the water.
- Fine filtration: to finalise filtration by retaining the finest particles, smaller than 1 micron, that may still be present in the water. This stage is carried out using a fibre or ceramic filter, which ensures crystal-clear water.
Limescale filtration is therefore a complete process that enables water to be treated effectively and sustainably, while preserving its taste and health qualities.
An advantageous solution from every point of view
Limescale filtration offers a number of advantages, both in terms of water quality and equipment preservation. By eliminating limescale, anti-limescale filtration saves water and electricity: limescale reduces the flow of water and increases the energy consumption of appliances. By preventing these deposits, anti-scale filtration helps to reduce water and electricity bills. What’s more, it protects equipment to extend its lifespan: limescale can damage the entire circuit. By protecting them from limescale, anti-limescale filtration prevents leaks, blockages, breakdowns and costly repairs.
To take advantage of these benefits, equip your water coolers properly with a range of anti-scale filtration products from Global Coolers, with products to suit every need and every budget. These filters can be fitted to water coolers to treat the water in the network, making it purer and healthier. These filters are made up of ion exchange resins, activated carbon and polyphosphates, which work in synergy to reduce water hardness, eliminate impurities and prevent the formation of limescale. They are easy to install, maintain and replace, and offer filtration capacities ranging from 5,000 to 20,000 litres. You can find out more about the anti-scale filtration range on the website of Global Coolers, the water cooler specialist.
