CAVITECH - Radically reduces energy use for wastewater treatment by means of energy-efficient wastewater aeration

The CAVITECH Solution aims at providing a profitable, energy-efficient, and ecologically healthy option to traditional wastewater aeration. To a greater extent, CAVITECH aims at providing a more sustainable wastewater treatment system. The solution enables to increase the access to decentralized wastewater treatment facilities and thus to boost the wastewater re-use for agriculture and industry. The radical reduction of the air used for the aeration reduces odours nuisance and exposure to harmful and dangerous aerosols, which include bacteria and viruses, for the operators' staff and the surrounding population up to 10km around the plant.

Key features

  • Reduces energy consumption by 60%-80% : Aeration Efficiency 5kgO2/kW-h to 10kgO2/kW-h compared to the mainstream alternative 1.5-2.0 kgO2/kW-h ( after 24 months of operation)
  • CAVITECH Aeration Modules are independent self-contained installations, which are deployed in Aeration Basins, report periodically its operational status and can be controlled remotely
  • Service Life of CAVITECH' Modules is more than 15 years, with very low cost of preventive maintenance - once per 6 years pump maintenance
  • Up to 80% less energy consumed and 80% less CO2 emissions
  • 5 times less odours, fumes, and harmful aerosols polluted, reducing risk exposure of staff and surrounding population up to 10km
  • Renewable energy sources can be used to power CAVITECH Aeration, making possible to reach energy neutrality or positivity


  • Operational Expenses of CAVITECH Solution are by 5-8 folds lower compared to the mainstream alternative, Fine Bubble Diffusers
  • CapEx of CAVITECH solution is by order of magnitude lower compared to the mainstream alternative

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
