When the water emerges from the spouts in a well system, a fountain array or especially in a water feature, it must be visually clear and must not present any health hazard.
However, the reality is often quite different:
Depending on location-specific environmental and human influences, water quality declines continuously. Unwanted substances (e.g. leaves, sand, faecal contamination from animals, left-over food etc.) enter the water circulation system all year wound. The consequence of this is often emerald-green water and spouts blocked by algae, turbid and foul-smelling water due to oxygen depletion and contaminants being carried in.
A reliable supply of clean and safe water must be guaranteed so that water features, wells and fountain arrays always remain an oasis for fun and relaxation.
This means that in locations where there is no constant supply from a natural fresh water source, the water must be kept in circulation and treated continuously. To us, water treatment does not just mean adding chemicals.
The purpose of water treatment is:
- Removal of physically problematical substances (e.g. impurities causing turbidity, organic carbon etc.) through oxidation and filtration
- Removal and deactivation of bacteria, viruses and germs through disinfection
- Control and adjustment of the pH value
- A continuous supply of pleasant, clean and odourless water
The water treatment is similar to the type employed in swimming pool water treatment. With the HYDROZON compact filter systems (e.g. installed in the TecBox P30), the water is treated in several stages:
- Flocculation: With the aid of a flocculant, agglomerates that are retained in the filter are formed from the substances and other particles in the water.
- Oxidation and disinfection with ozone: Ozone is an outstanding oxidation medium and disinfectant. Its high oxidation potential brings about rapid oxidation of organic and inorganic substances in the water. This deactivates micro-organisms. Following a reaction with the water components, ozone breaks down into oxygen and activated carbon also converts any surplus ozone into oxygen.
- Filtration: The undissolved water constituents and particles are removed at the filtration stage. Micro-flakes and macro-flakes from the flocculation process are retained at the same time.
- pH value adjustment: pH value fluctuations can occur as a result of calcareous constituents leaching out on water-bearing surfaces or from acidic rainwater. These are balanced out during the process by means of dosing, in order to keep the pH value in the neutral range at pH 7.
