Water and wastewater treatment

Services for the water sector

Process optimisation

Treatment process optimisation

  • Improve mixing (e.g. cure dead (stagnant) zones)
  • Optimisation of hydraulic residence time (assuring disinfection, preventing regrowth)
  • Limiting byproduct formation
  • Optimisation of gas/liquid transfer (ozonation, aeration)
  • Optimisation of coagulant/flocculant dosing
  • Determination of optimal sensor location
  • Improve effluent quality
Process design

Effective design and retrofitting of treatment processes

  • Storage/contact tanks
  • Water towers and distribution systems
  • Drinking water reservoirs (e.g. raw water intake ponds)
  • Ion exchange columns
  • Flotation and settling processes
  • Disinfection and oxidation processes
  • Membrane filtration
  • Activated sludge processes
  • Wastewater stabilization ponds
  • Membrane bioreactors
  • Aeration systems
  • Anaerobic digestion
  • Primary and secondary settlers
Process scale-up

Accelerated scale-up

  • Saving scale-up costs (e.g. omit/limit piloting)
  • Increase piloting effectiveness
  • Decrease time to market
  • Co-creation of unique ip together with technology developers (new inventions)
