About

Like in a disinfected pool bath....

...the swimming pool with biological water treatment also consists of a usage area (in-situ) and a treatment area (ex-situ), which is usually outsourced. What is the depot effect of the disinfectant in the pool water in the disinfected pool is the following degradation mechanisms in a biological swimming pool:

  • Filtration by zooplankton

  • Competitive situations of microorganisms

  • natural UV light.

This means that harmful germs, viruses and protozones are also broken down in the area of use.

The use of biological water treatment systems such as filter systems and hydrobotanical systems must ensure that the bacterial count in the pool water is minimized. So that the guideline values required by law for the indicator germs E. coli, enterococci and Pseudomonas aeruginosa secure
be complied with.

Every year, millions of people around the world enjoy carefree bathing in swimming pools with biological water treatment, which sometimes have the character of a pool and sometimes the character of a swimming pond.

The latest news on the international development of swimming pools with biological water treatment can be found on the "International Organization for Near-Natural Bathing Waters" (IOB).

The many successful systems installed worldwide are clear proof of the functionality and safety of the system.
