Biological treatment is a close cooperation between water, air and bacteria’s. The single decisive factor for a trickling filters result is how big of contact area between air and water you have. Our trickling filter material PLASdek and BIOdek has a structure that gives a large and effective contact area between air and water. One single cubical meter contains a contact area up to 243 square meters!.
- Trickling filter media is used as a filling material in trickling filter beds and bio-rotors at both municipal and industrial Waste Water Treatment Plants.
- Large contact area air/water.
- The cross fluted filter distributes the water evenly inside the bed which makes the flow trough time long and maximizes the performance. The material carries its own weight and thus there is no unnecessary load on the tank walls.
- Low pressure falls, airflow by its own air draught.
