Transport characterization in flat reverse osmosis membranes: Utilization of the Kimura-Sourirajan analysis method for the determination of mass transfer coefficient K, transport parameter [formula omitted], and permeability constant A

A study was carried out on a NaCl H 2O RO thin film composite reverse osmosis membrane system to characterize these membranes, determine their performance and predict the effects of pressure and solute concentration in the feed using the correlation from the Kimura Sourirajan analysis.

Description
Summary:A study was carried out on a NaCl H 2O RO thin film composite reverse osmosis membrane system to characterize these membranes, determine their performance and predict the effects of pressure and solute concentration in the feed using the correlation from the Kimura Sourirajan analysis. The effect of the solute concentration in the feed (0.0043–0.086 molal) operating at pressures of 500–2000 kPa was studied. The permeability constant, A, and the transport parameter D Am kδ for CA 990 PP and HR 98 PP flat membranes were calculated and the results from both membranes were compared. The M20 lab unit had a total permeation surface of 0.72 m 2 when all 20 membrane pairs were installed. During the experiments one pair of membranes was installed, resulting in a permeation surface of 0.036 m 2.
