The GUNT Biofilm Process Unit demonstrates biological wastewater treatment using fixed biofilm processes in a trickling filter setup. It provides insight into organic substance degradation and nitrification.
Product Features
- Wastewater pumped to the upper end of the trickling filter and distributed via rotary distributor
- Fixed bed filled with special carrier material supporting biofilm growth
- Microorganisms form a thin biofilm layer that biologically treats wastewater as it trickles down
- Organic degradation predominates in the upper filter region; nitrification (ammonium oxidation) predominates in the lower region
- Wastewater collected in a tank with recirculation pumps returning portion to rotary distributor
- Natural convection aeration openings in lower filter region or optional compressor aeration
- Biofilm production via filling trickling filter with carrier material, wastewater, and activated sludge
- Activated sludge continuously discharged to secondary clarifier and pumped back to filter
- Compressor aerates trickling filter to support biofilm growth
- Adjustable flow rates: wastewater, recirculation, aeration (compressor)
- Adjustable rotary distributor speed
- Sampling points enable concentration profile analysis
- Requires activated sludge from wastewater treatment plant
- Recommended analytical parameters: biochemical/chemical oxygen demand, ammonium concentration, nitrate concentration
Benefits
- Provides hands-on understanding of biofilm processes in wastewater treatment
- Enables study of organic degradation and nitrification in fixed bed systems
- Flexible control of flow rates and aeration for process optimization
- Ideal for teaching environmental engineering and biological treatment principles
