2H BIOdek® Vertical-Flow Fills

Optimum Water Circulation and Sludge Removal in Biological Processes

By free selection of the sheet thicknesses highest mechanical strength is achieved for a long design-life. 2H BIOdek® is resistant against rot, fungi and most chemicals. UV protection additives are part of the compounds.


In our manufacturing process we use premium quality materials for high quality requirements. With our unique welding process fills can be assembled at any place of the world environmentally friendly, safe and avoiding the usage of solvents.


For more than 40 years we have been consistently developing and improving fills for trickling filters and contact aeration. This puts us today in the position of a leading supplier of biofilm technology. You may profit from our experience gained in equipping hundreds of plants with fill media. We will be glad to support you in the design of highly efficient, energy saving trickling filters and submerged fixed beds.

Features of our 2H BIOdek® Vertical Flow Fills:


• Optimum structure ensures sludge removal and water circulation

• Freely selectable foil thickness for high bearing loads

• No memory effect

• Environmental friendly, impact and ageing resistant PP

• PVC optional with reinforced edges

High performance results in high biomass growth! 2H BIOdek® with vertical channels reliably releases excess sludge of trickling filters or of submerged applications. Even at low recirculation rates they enable safe operation of concentrated waste water or application of high volu-metric loads. The straight channels ideally support the water circulation in submerged contact aeration.
