However, in natural baths without chlorine use, it is necessary to prevent zones with reduced current since they cause hygienic problems.

The company EKO-PLANT GmbH developed a »computer-based hydro-dynamic current model« which stands for guaranteed purity and secures the perfect bathing in natural baths. In the planning phase, the procedure facilitated to calculate the optimal currents of the basin and to visualize them on the computer.

In operation, impurified basin areas can be specifically determined and cleaned with help of the process management system and the specific technology. This instrumentation and control technology, installed in the EKO-PLANT natural baths, facilitates the complete exchange of the entire water volumes. The new model developed with different partners has already been tested successfully many times. With the corresponding control engineering, the hydro-dynamic model increases the operational safety in natural baths and helps to minimize the overheads.
