In a study of wastewater reclamation for potable reuse, a multiple treatment
barrier approach was required to provide safe water as a drinking water source. High-pressure
membranes, including nanofiltration (NF) and/or reverse osmosis (RO)
membranes, can play an important role in wastewater reclamation as an effective barrier
to pathogenic microorganisms, dissolved organic carbon (DOC) that reacts with
disinfectants to form disinfection byproducts (DBPs), as well as endocrine disrupting
compounds (EDCs) and pharmaceutically-active compounds (PhACs). Recent research
suggests that effluent organic matter (EfOM) present in wastewater secondary effluent is
a constraint to implementing the use of RO and NF membranes due to the significant role
of EfOM in membrane fouling. Soluble microbial products (SMPs) have been found to be
a significant fraction of EfOM from biological treatment processes, and their presence
contributes to fouling of high-pressure membranes (Barker et al, 2000). This study
focused on the role of the SMP associated with the EfOM from wastewater secondary
effluents in fouling of high-pressure membranes, i.e., NF and RO membranes. The SMP
source (feed) waters were generated from bench-scale sequencing batch reactors (SBR).
A glucose solution was used as carbon/energy source for microorganisms in the activated
sludge system. Fouling of high-pressure membranes by the SMP was investigated. Includes 6 references, tables, figures.
