Mecana AG
About
Mecana AG, a Swiss firm headquartered in Reichenburg, has built municipal and industrial water and wastewater treatment plants since 1964, working in both biological and chemical-physical processes. The company originated polystyrene fibre (Polstoff) filtration and counts some 170,000 square meters of installed filter area worldwide. Its pile cloth media filtration, introduced in the late 1990s as a branch of cloth filtration, passes water through a fibre layer where surface sieving combines with genuine depth-filtration effects, an approach noted for modest footprint and energy demand. Alongside the filters, the long-running catalog includes scraper systems, disc diffusers, and compact treatment plants. Paired with polishing technology, Mecana's processes address current industry requirements, including the elimination of PFAS.
