This slide presentation outlines information on the integration of membrane bioreactor (MBR) technology and desalting membranes for water reuse. Project objectives include: evaluate MBR systems recently introduced to the U.S.
market;
assess the impact of adding coagulant and
polymer to the MBR feed water on MBR performance;
evaluate MBR performance under extreme operating
conditions (increased flux, low HRT); evaluate several different desalting membranes
(NF/RO) following pretreatment by MBR;
perform cost analysis by comparing cost of
conventional and MBR as pretreatment to RO, and by
determining the cost associated with RO during
wastewater reclamation; and,
evaluate the ability of commercially available
MBR/RO process units to remove EDC/PPCPs
from advanced primary effluent. The materials and methods outlined include: pilot testing performance; pilot treatment train; new and established suppliers of MBR pilot systems; MBR membrane specifications; desalting membrane specifications; MBR pilot operating conditions; RO operating conditions; MBR performance data including particulate removal, organic removal, inorganic nitrogen removal; MBR microbial rejection; RO performance data including water quality data; EDC/PCPPs Analysis; cost analysis; conventional train; MBR train; cost items: ditch + MF and MBR; cost items: chlorine contact and ultraviolet (UV); and, cost items: reverse osmosis.
