ECOFARIO has developed an innovative separation process based on hydrocyclone technology which, by installing it as a mechanical final stage in municipal or industrial sewage treatment plants, significantly reduces the discharged microplastic load and the associated pollutants. Unlike alternative filtration methods such as micro-, nano- ultrafiltration and reverse osmosis, this new technology allows skipping an active filter medium, thus enabling volume flow rates of virtually unlimited size without the otherwise mandatory flushing sequences and long service downtimes.


  • Concept based on hydrocyclone technology

  • Extreme performance increase through patented modification of the hydrocyclone principle

  • Modular design

  • Applicable from small municipal to big urban wastewater treatment plants

  • Can be integrated into almost every waste water and process water cycle

  • Relatively low investment and maintenance costs compared to micro, nano and ultrafiltration

High-G-Separator (the core component)

At the heart of the ECOFARIO technology are hydrocyclone-based High-G-Separators:


The focus while developing the ECOFARIO technology was the filter medium-free, hydrocyclone-based separation of microparticles with a low density difference to water from contaminated aqueous media with a separation accuracy of up to 97%. This focus is pursued because conventional filtration methods for the production of clear water such as micro-, nano- and ultrafiltration bring some procedural as well as economic disadvantages. Although it is possible with these methods to filter off microplastic particles to a certain extent, the process effort and the associated costs are significant. Thus, the ECOFARIO technology is the cheaper and more efficient alternative to existing technologies.
