Sander Submers - Biofilter
The Sander Biofilter Model Submers has a continuous rinsing process. During the rinsing the biofilm surface of the filter media is in an uninterrupted washing process. Therefore, the plugging and clogging of the filter is being avoided. Sander Biofilter Submers are suitable for fresh and seawater.
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.
