MBR Costs

MBR Capex & MBR Aeration costs

The feasibility of a MBR based wastewater treatment plant when it is technically possible to meet the effluent quality following different technical options depends on the best compromise between the capex and the Opex.




  • Pretreatment unit
  • Tanks
  • Reactor blower
  • Membrane tank blower
  • Pumps
  • Control and monitoring equipment




  • Energy for pumping
  • Energy for aeration
  • Sludge treatment and disposal
  • Chemicals


In general, for low strength waters with high flow rates, a CAS based solution will be more cost-effective, but for high organic loads with relatively los flow rates MBR will be the best economic solution.
