Flush-water-recycling in a closed cycle - biological primary treatment and electrolysis
Viewed from the outside, the user sees no difference to a conventional flush toilet.
After flushing the toilet, the waste water (urine and faeces mixed) enters a sedimentation tank. Here, most of the solids are disintegrated by bacteriological treatment, non-organic residues settle on the bottom of the tank. The remaining liquid passes through the electrolysis reactor (20 l), where it is converted into sterilized, crystal-clear water and finally reused for flushing the toilet again.
This innovative combination of bacterial treatment and electrolysis enables almost unlimited reuse of the water in a closed circuit.
Production of water and compost
The permanent addition of urine increases the volume of fluid in the circulation. This surplus can (according to official regulations) be used to clean the cabin or as irrigation water near the toilets.
The sediment in the primary clarification tank must be pumped out at intervals of three to twelve months. The frequency varies depending on the number and profile of users.
The sewage sludge can optionally be composted. Following the terms of the circular economy, the WeCo toilet recycling system does not generate any waste and does not consume any resources.
