Effect of Seawater Variability on Endemic Bacterial Biofouling of a Reverse Osmosis Membrane Coated with Iron Nanoparticles (Fenps)

•Biofouling study of endemic bacteria on iron nanoparticle coated membrane.•The Sea of Cortez water has a high potential to biofoul the Reverse Osmosis membranes.•Physicochemical parameters values of El Sol Beach water delay biofilm growth.•Temperature, pH and dissolved oxygen affect directly the biofilm growth.•Temperature, pH and dissolved oxygen improve iron nanoparticle coating effectiveness.
