Unlike some years ago, there are now many swimming pools choosing more and more often other models of maintenance, leaving aside chlorine and other chemical products that are harmful to the environment and our health.
Sustainable and environmentally-friendly swimming pools or those which replace chlorine for salt water are two of the most widespread options used. We will tell you what these two less polluting models consist of.
Environmentally-friendly swimming pools
Apart from being able to integrate fully into their settings, these kinds of sustainable swimming pools are healthy for both the environment and swimmers. They have been used for twenty years now in Europe, and their use is becoming more and more widespread because in the long term you can save money which is usually spent on chemical products and maintenance.
Plants and stone or sand are used to purify the water rather than chlorine. This emulates the natural filtration which takes place in rivers. It can be understood as an artificial pond but with purification, and creates a micro-ecosystem (all their natural elements integrated are related to each other).
How do they work?
1. Water must be in motion, so it is necessary for the swimming pool to be built on a certain slope.
2. This motion is generated by a power pump –which can be derived from a solar power supply in order to save even more energy.
3.The plants, placed in another space separate from that meant for swimming, are responsible for filtering waste.
4. Stones and sand are also natural filters that naturally remove those impurities and bacteria found in water.
- Water saving (there is no need to empty and refill them; you just have to replenish the part that evaporates).
- Energy saving (filter systems are not necessary).
- They do not use chemical products.
- They do not harm your skin, eyes and mucus health.
Salt-water swimming pools
These swimming pools employ salt to generate chlorine but they are not pollutant because once hypochlorite has been generated, chlorine decomposes and turns back into salt.
That salt employed is the regular one, so it is natural too, and it is much less expensive than those traditional chemical products and chlorines.
Furthermore, salt concentration is ten times less than that found in the sea, so it does not irritate their users’ eyes and skin.
Can you imagine a swimming pool like a natural lake? Or forgetting about having your eyes irritated and your hair spoilt? Tell us if you have ever tried one of them and what the experience has been like!
