Polymer surface nano-structuring of reverse osmosis membranes for fouling resistance and improved flux performance†
A new class of surface-structured RO membranes was developed with a hydrophilic brush layer of terminally anchored polymer chains resulting in fouling resistant membranes of low mineral scaling propensity and high permeability. The approach is based on free-radical graft polymerization of a suitable monomer, onto the active polyamide (PA) layer of a thin film composite (PA-TFC) membrane, post-s...
متن کاملBacterial adhesion onto nanofiltration and reverse osmosis membranes: effect of permeate flux.
The influence of permeate flux on bacterial adhesion to NF and RO membranes was examined using two model Pseudomonas species, namely Pseudomonas fluorescens and Pseudomonas putida. To better understand the initial biofouling profile during NF/RO processes, deposition experiments were conducted in cross flow under permeate flux varying from 0.5 up to 120 L/(h m(2)), using six NF and RO membranes...
متن کاملEffects of chemical preservation on flux and solute rejection by reverse osmosis membranes
This study investigates the impacts of chemical preservation on the performance of polyamide reverse osmosis membranes with respect to water permeability and solute rejection. Three preservative chemicals, namely formaldehyde, sodium metabisulfite, and 2,2-Dibromo-3-Nitrilopropionamide, were evaluated for membrane preservation at pH 3 and 7. Experimental data show that chemical preservation may...
متن کاملConcentration Polarization in Reverse Osmosis Membranes: Effect of Membrane Splitting
We propose a simulation study in order to evaluate the effects of concentration polarization damping by splitting a single spiral-wound membrane module in two units connected in series inside the same shell. The reverse osmosis process in each unit is described by the advection-diffusion equation in two dimensions which is solved by a finite difference technique. Several feed regimes and operat...
متن کاملSalt cleaning of organic-fouled reverse osmosis membranes.
Cleaning of organic-fouled reverse osmosis membranes with concentrated salt solutions has been investigated. Polysaccharides (alginate and pectin) and Suwannee River natural organic matter were used as model organic foulants. By systematically varying the chemical and physical factors affecting salt cleaning efficiency, we were able to elucidate the processes and mechanisms involved during salt...
