MET4Grey - Give water a second life
Head R&D Department at METfilter S.L.

About
MET4grey® collects greywater from showers and sinks and directs it to a storage tank. The water then passes through two modular greywater treatment systems based on METland® technology, where electroactive microorganisms remove organic matter and other pollutants. Finally, the water is disinfected, stored, and ready for reuse in non-potable applications on-site such as irrigation or toilet refilling.
