CE 701 Biofilm Process
Education / GUNT Hamburg / Process Engineering / Water Treatment /
description

The fixed biofilm process is an aerobic, biological process. CE 701 provides a detailed demonstration of this process. 
  A pump delivers the raw water from a tank to the upper end of the trickling filter. The trickling filter contains a fixed bed made of a special carrier material. A thin layer of microorganisms (biofilm) forms on this carrier material. A rotary distributor is used to distribute the raw water evenly over the fixed bed. Oxygen can be supplied to the microorganisms in two different ways: by natural convection or with a compressor. Detached parts of the biofilm are subsequently separated from the water by sedimentation in a secondary clarifier. Part of the treated water can be recirculated.
  The distributor speed is adjustable. Samples can be taken at all relevant points.
