Maintaining a certain pH level in recreational water is the prerequisite for safe water play. This applies not only in a swimming pool, but also in water playgrounds in public spaces. Read more below about what the pH balance means, why it is important for water games and how it can be regulated.
Acidic & Salty
Absolutely pure water is not a natural occurrence; even the purest water found in nature, rainwater, contains ‘impurities’ in the form of dissolved gases, namely oxygen, nitrogen and small amounts of carbon dioxide, as well as sulphur dioxide in densely populated areas in particular. Carbon dioxide and sulphur dioxide react with the water to form acids: Carbonic and sulphuric acid. As these acids in rainwater can dissolve certain saline substances from rocks and the soil, our groundwater and surface water may contain both salts and gases.
The importance of water quality
It is important to control the levels of these substances in water that comes into contact with our bodies, for example while swimming or playing with water. Our skin contains an acid protection agent that consists of fatty acids. This protective layer keeps the skin supple and protects it against the ingress of bacteria. If the skin comes into contact with acids (e.g. in water or soap), thay can break down the protective layer and make our skin feels dry and flaky. Our eyes and some other mucous membranes are even more sensitive to such substances than our skin. It is therefore important to closely regulate the acidity of recreational water.
pH levels in balance
While the acids in water can be harmful to our bodies, they also help to control the levels of bacteria and impurities it contains. Either chlorine or active oxygen is often added to kill bacteria and break down impurities. It is nevertheless necessary to find a sutitable balance: Recreational water has to be both skin-friendly and bactericidal. This balance is measured on the basis of the acidity (or alkilinity) of the water, which is expressed in pH (pondus Hydrogenium, which is Latin for quantity of hydrogen). Bathing water generally has a pH level of between 7.2 and 7.6. Water containing such levels does not irritate the eyes, although it does ensure that bacteria are kept under control, while preventing the formation of limescale on the swimming pool equipment (such as the walls and joints, play elements, the filter and the heat exchanger).
Safe water attractions
We set great store by safe and healthy water quality in our water attractions. Our spray parks also use water that is of swimming pool quality. If the spray park play equipment is installed in a pool, but on a floor without standing waterdepth, such as next to a swimming pool or in the public space, then we also supply a separate water treatment system. This system continuously monitors the pH level, and automatically administers chlorine or acid whenever necessary. In some cases, this process can be remotely monitored by means of an app.
Watergames & More supplies turnkey water attractions, including spray parks and water slides, from design to installation and maintenance. We would be pleased to advise you on the possibilities of constructing a water attraction at your site, including the control of water quality that this entails. Please contact us personally for further information.
