Biological sewage treatment plant Crosspack 22

This is a honeycombed structure designed for the biological purification of modular chamber and circular trickling filters. CROSSPACK 22, the filling common to all our trickling filters, is used to produce facilities with a high level of biological purification. It is suitable for all heights and all forms of trickling filters. These structures are characterised by: A specific and adapted surface. A honeycombed structure that minimises clogging risks. An assembly of smooth sheets that allows for a good control of the biofilm thickness (with the biomass drawn by its own weight), as well as restricting the development of anaerobic bacteria.
