MBR costs − an overview
There are a number of factors to consider when implementing MBR technology, most importantly capital cost and operating costs
MBR costs
Membrane bioreactor costs
Topic
Aeration costs in MBRs
Membrane aeration for scouring an immersed membrane is a key contributor to energy consumption in the operation of an MBR
Topic
Sludge pumping costs in MBRs
Sludge (or mixed liquor) transfer is often the second most significant contributor to MBR total energy demand after aeration
Topic
Membrane permeation costs
Costs for pumping water through the membrane relate to the transmembrane pressure (TMP), the flux and the operating protocol
