Natural
swimming pools
Public and private swimming pools can be
designed as natural outdoor pools with a highly aesthetic biotope
appearance and without using chemicals like chlorine.
For the natural purification of the nutrient load (nitrogen and
phosphorus) and a hygienically safe state, the pool water is
re-circulated between the swimming area and a regeneration zone, which
consists of planted soil filters for an environmentally friendly water
treatment.
In 2006 we realized the
redevelopment of the conventional bath pool in the city of Goettingen,
Germany, in a natural pool. The treatment is implemented by constructed
wetlands and shows the natural character of the system.
The
water
treatment plant is dimensioned for an average number of approx. 1,200
swimmers per day. It works without any chlorine or chlorine dioxide. We
apply a special filter material to realize continuous high flow rates
on the one hand and an effective treatment concerning disinfection and
turbidity on the other hand. The regeneration and following
recirculation of the treated water bases only on biological and
physical processes.
