Division 1: Process Technology

Process Technology within Wastewater, Water and Solid Waste Treatment

  • Nutrient Recovery ( Phosphorus: Crystallisation Technology, MAP Precipitation; Nitrogen: Ion Ex-change using Zeolites)
  • Enhanced Wastewater Treatment (Precipitation, Flocculation, Phase Separation, Chemical Oxidation Processes)
  • Application of Sophisticated Measurement Tools (Zeta Potential, Particle Size Distribution (PSD) and Settling Velocity)
  • Concept Development for Industrial Wastewater and Leachate Treatment
  • Characterisation of Organic Substrates for their Suitability as External Carbon Sources and their Gas Production Potential within Co-Digestion
  • Quantification of the Co-digestibility of Solid and Liquid Organic Wastes
  • Sewage Sludge Treatment, Conditioning and Valuable Matter Recycling
  • Optimisation of Wastewater Chemical’s Application
  • Energy Optimisation
  • System Analysis, Supervision and Consulting of Plant Operators, Industry and Water Authorities

Biofilm Technology

  • Rotating Biological Contactors (RBC) for Municipal and Industrial Wastewater Treatment
  • Suspended Carrier Media (MBBR) to increase the Capacity of Activated Sludge Systems and to Unload the Secondary Clarifiers
  • Biofilm Characterisation (Biofilm Thickness, Oxygen Profiles, Activity Tests)
  • Simulation of Biofilm Systems
