In this study rapid bench-scale membrane tests (RBSMT), conducted using protocols published by the U.S. Environmental Protection Agency (USEPA) in
the Information Collection Rule (ICR), were performed to evaluate microcystin-LR (m-LR) algal
toxin removal by high pressure membranes. Testing was limited to thin film composite
polyamide nanofiltration (NF) and reverse osmosis (RO) membranes due to the relatively low
molecular mass of the m-LR algal toxin (< 1100 Daltons). Water mass transfer coefficients
(MTC) (aka specific fluxes) for the selected NF and RO membranes ranged from 0.1 to 0.4
gfd/psi and from 0.3 to 0.8 gfd/psi, respectively.
The paper summarizes the characteristics of the flat sheet membranes utilized in this study. These
membranes represent currently utilized membranes for drinking water applications. They were
selected to provide a wide range of membrane types to evaluate treatment of m-LR. Low
fouling RO membranes were specifically included in the testing based on their superior
performance in treating high organic, moderately brackish surface water supplies in Florida. Includes tables, figures.
