The steps towards an ecological future
From grey water to process water: Here you can understand step-by-step how Pontos AquaCycle systems work:
1. Pre-filtration
First any coarse particles in the incoming shower and bath water (e.g. hair and fluff) are filtered out. Residues flow into the drainage system. The filter is automatically backwashed.
2. Two-fold biological treatment
First stage of biological treatment: micro-organisms remove water contaminants – by supplying atmospheric oxygen. The substrate in the containers (foam cubes) provides the micro-organisms with the surfaces they need to settle on. The system pumps the water on during the second stage of biological treatment. Here the process is repeated.
3. Sediment disposal
Sediments generated during the biological treatment process are automatically drained off into the drainage system at fixed regular intervals.
4. UV hygienisation / sterilisation
The water now flows through a UV lamp which performs sterilisation. It is stored in the process water tank until it is reused. The quality of the purified water conforms to the hygienic requirements of the EU Bathing Water Directive 76/160/EC.
5. Pressure pump
Let the process water flow! The pressure booster system takes the treated water to the consumption points, for example to the toilet flushing system. It also supports the automatic filter backwash system.
6. Automatic drinking water top-up feed system
If there is not enough process water available, the automatic drinking water top-up feed system fills up the storage tank so that consumption points have a secure supply. Where there is a combination with rainwater, rainwater can be fed in initially instead of drinking water.
