Wave pool

A wave pool is a swimming pool where artificial waves are produced. Thus the bather is mediated an experience that comes closer swimming in the sea than in classical swimming pools.

Technique of wave generation

There are several designs of wave machines. What is each used depends in particular on the size of the bath and the desired size of the shaft. In smaller tanks, compressed air is blown onto the water surface, so there is no pendulum used is water. In contrast, displacement body or swing wings are used for medium wave sizes mostly, which have a pneumatic ( indirect ) or mechanical ( direct ) drive. Another possibility is " accordion-like " bellows, which compress air through pressure and thus express water or reopen and thus collect water. For large bathrooms finally mostly a large amount of additional water (pendulum water) is supplied from a few meters higher ground reservoir suddenly in the wave pool, which creates the wave by fast displacement. The pendulum water is then pumped back continuously from the tank into the reservoir. This technology also wave heights of up to 3 meters can be achieved. In some wave pools even descending the breaking wave with a surfboard is possible. In systems with spherical water of the pool water level is lowered before the start of wave operation, so that the water does not overflow at wave operation. The Absenkwasser is either in the raw water storage (formerly Splash container ) or buffered in a separate container.

Safety aspects

Wave pools provide the supervisory staff and swimmers before increased demands. Due to the continuous movement of the water surface, the changing optical refraction of the surface and reflections, it is difficult to identify people in need. Also, some swimmers overestimate their abilities under the difficult conditions with waves swimming. Therefore, the operator of the wave pools dispense generally to wave height.

Water treatment

The wave pool and possibly the shaft chambers must be flowing outside and during wave operation continuously with chlorinated pure water. If a separate container used for the Absenkwasser, so there must also be circulated and chlorinated water in accordance with DIN 19643 at a caching duration of about 20 minutes.
