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.
Capex
- Pretreatment unit
- Tanks
- Reactor blower
- Membrane tank blower
- Pumps
- Control and monitoring equipment
Opex
- 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.
