This paper presents the results from a Membrane Bioreactor (MBR) system energy analysis and an ongoing air-scour energy optimization study. The energy analysis was conducted on the major MBR system components that include the RAS pump, permeate pumps, and air scour blower. Preliminary energy consumption and membrane transmembrane pressure (TMP) re...

The implementation of potable reuse will require treatment processes with multiple barriers to prevent microbial, nutrients, and other contaminants of concern from compromising public health. The osmotic membrane bioreactor (OMBR) is a multiple barrier that is comprised of three treatment barriers: biological treatment for carbon and nutrient remov...

This paper describes a hybrid ultrafiltration forward osmosis-osmotic membrane bioreactor (UFO-MBR) as a multi-barrier reuse technology that has been studied at the pilot level continuously in the last three years. UFO-MBR treatment has been shown to almost completely remove conventional wastewater contaminants (carbon, nitrogen, and phosphorus) an...
