Vuna offers you a complete and up-to-date overview of possible systems and technologies for your sanitary facilities. We plan and build tailor-made systems for you and select the most suitable wastewater treatment for your situation.

Are you looking for a decentralized wastewater treatment system? Our solutions are based on the separation of material flows. Urine, faeces and greywater can be separated and treated individually. We apply the following technologies:

  • Dry and/or separation toilets
  • Treatment wetlands
  • Gravity-driven membrane filters (GDM)
  • SBR (Sequencing Batch Reactors)
  • Urine recycling technology
  • Vermi-composting

With the ingenious combination of technologies, we offer solutions which close water and nutrient cycles.

You are not connected to the drinking water system? We offer filters, which ensure drinking water quality.

Do you have a farm? We use the Vuna process to stabilize farm slurry, which reduces ammonia emissions.

We have a dense network of consulting companies,
manufacturing companies and licensing authorities and thus guarantee a smooth execution of your project. We offer:

  • Feasibility studies
  • Planning
  • Building
  • Research
  • Accompanying authorisation procedures

For a detailed initial assessment of your project, we would be happy to come and visit you.
