Algae in the pool

There is one thing every pool owner would like to avoid: the heavy build-up of algae in the form of floating algae, filamentous algae and blue-green algae, which occurs even though you have spent a lot of money on the pool and the associated technology. Algae are not only unsightly, they also significantly impair the water quality. They can greatly increase the pH value of the water, which can lead to corrosion-related failure of pumps and pipes. However, you are not defenceless against this algae plague. There are a variety of ways to deal with this problem. Even if these methods differ from one another, the basis is always a HEPA filter that filters out coarse particles. Normally, sand filters or backwash filters are installed in pools, which are coupled with a corresponding water pump. These pool accessories achieve a basic cleanliness of the pool, but do not provide effective protection against algae infestation, as algae are too fine to be sucked up by these filters.

DISINFECTION WITH CHEMICALS

To get really crystal-clear pool water, you need a disinfectant. There are chemical and physical methods, with chlorine being the best known of the chemical methods. Water disinfection with chlorine has the disadvantage that the pH value of the water increases and pH value reducers must be used. In addition, other chemicals such as flocculants are often used. These toxic substances are permanently present in the pool water and prevent the formation of algae over a longer period of time (depot effect). It should not be forgotten that the disinfectant can also be dangerous for humans: Children can accidentally drink the water and it is harmful to the eyes and skin. It also has far-reaching ecological disadvantages: Pool water that has been disinfected with chlorine and other chemicals is hazardous waste and must be specially disposed of. It is therefore impossible to use this water as an alternative, e.g. for watering the garden.

ECOLOGICALLY AND ECONOMICALLY COMPATIBLE DISINFECTION WITH UV-C LIGHT

One form of water disinfection in a swimming pool that has received little attention to date is physical disinfection, which involves treating the water with UV-C light. In this variant, a UV-C system is placed between the filter and the water in the pool. This illuminates the water with a high UV-C output, which specifically breaks down the algae's DNA, rendering it harmless or inactive. The result is disinfected water without algae and bacteria, which can be used as pool water without any concerns. Without the disadvantages of one of the chemical processes and from an ecological point of view, the disinfected water can later be used for watering the garden without any problems. At the same time, this process pays off as it is significantly cheaper in the long term than the use of various chemicals. With the UV-C method, the owner of the pool is only responsible for permanently checking the pH value, as acid rain, for example, can bring it into an unfavorable range. This can result in damage to the pool and the associated technology.

THE DREAM OF A CRYSTAL-CLEAR POOL

Every pool owner wants to have a pool with crystal-clear water that is a visual highlight in the garden and that both children and adults love, without too much effort and with a clear ecological conscience. With the help of the effective UV-C disinfection process, this dream becomes a reality.
