Sander - Biological Trickling Filters

Sander’s Biological Trickling Filters are filled with filter media that is being sprinkled with water via a trickling tube. On the sprinkled filling material, a so-called bacteria bed grows up over time. Surplus material will be led out together with the sprinkling water. A constant gas exchange is one of the advantages of this trickling filter. This gas exchange grants a constant oxygen supply of the bacteria and on the other hand harmful gas as e.g., CO₂ and/or Nitrogen (N₂) are being emitted into the air. An additional ventilation is not required. Sander’s Biological Trickling Filters are suitable for applications in fresh and in seawater.
