The Hydrobalance Filter

Detailed information regarding the Hydrobalance Filter System

First and foremost the Hydrobalance Filter System stands out due to its closeness to nature. Supporting biological action, just as it naturally happens in rivers, the filter system maximizes the decomposition and absorption of nutrients with the minimum use of energy. Due to its compact building system and flexible options for installation the Hydrobalance Filters can be fitted in all natural Pools without any need for additional space. The filter consists of a fabric made of randomly arranged Polypropylene and Polyamide wrapping the inner layers of mineral wool. Inside the filter, you will find a drainage and a collecting pipe. The filters are covered with washed, phosphate free round gravel 4/8 and 16/32 and are partly overlaid with a plant substrate.

The filter can be placed in a separate small pond section, the skimmer pond, and can be positioned in the direction of the prevailing wind. The water is sucked in via the filters and then pumped to the opposite side of the pond via the pump, to then be channeled into the pool by means of a stream, a source or a simple influx opening. Thus, a surface current is created in the prevailing direction that transports foliage and petals into the filter or the skimmer pond, where they can be easily removed with a fishing net.
The Hydrobalance filters can also be installed in the pool banks or in the swimming area of the natural pool. The filter does not need any light and therefore can be installed in shaded areas (for example at great depths such as underground wells and similar).
The filter system is based on the principle of mechanical, biological water purification. Mechanical filters will carry out the removal of firm mineral and organic particles. This supports the biological purification process. The Pre-Filtering is already carried out via the layers from gravel 16/32 and 4/8.
The biological purification processes cause the transformation of microscopically small substances or solute. This is done by microorganisms, which settle at the surface and in the gaps of the run-through filter substratum. The bigger this surface, the bigger the habitatavailable for the microorganisms.
The more diverse an environment that can be arranged, the better the whole system works asthe different types of microorganisms prefer different aquatic conditions (for example aerobic versus anaerobic areas in the water).

Slow flux filters, used primarily for the purification of drinking water, filter out particles which are microscopically small up to bacterium size. Thus, they guarantee crystal-clear water and optimal hygienic conditions. Fast flow filters build upan oxygen supplied bio film on the surfaces, which binds the mineralized nutrients. Thus, the content of nutrients is reduced and the growth of algae in the water prevented.

Hydrobalance is the only filter system combining slow and fast filters in a joined system.
Due to the simple design system and the flexible options for installation, faults can be prevented, and a steady flow to all areas can be guaranteed.
Our filter systems generally need very little maintenance and are extremely long-lasting. Since starting to use this kind of technique in 1998, no Hydrobalance Filter system has worn out and needed to be exchanged.
