Characterization and effect of biofouling on polyamide reverse osmosis and nanofiltration membrane surfaces.
Biofouling is a major reason for flux decline in the performance of membrane-based water and wastewater treatment plants. Initial biochemical characterization of biofilm formation potential and biofouling on two commercially available membrane surfaces from FilmTec Corporation were investigated without filtration in laboratory rotating disc reactor systems. These surfaces were polyamide aromati...
متن کاملPhysiochemical Control of Composition and Location for Fundamental Studies of Biofouling Resistant, High Fouling Release Surfaces
Ideal marine antifouling/fouling release surface coatings should be non-leaching and nontoxic, while effectively resisting the attachment of marine organisms or easily releasing them postattachment. This program aims to fundamentally understand the spatial and temporal chemistry and physics required for new polymer-based antifouling surfaces, based on dynamic structures which respond to their c...
متن کاملPilot Plant Studies on the Recovery of Caprolactam by Reverse Osmosis
The performance of a polyamide-based thin film composite reverse osmosis membrane (RO) in a spiralwound element BW3025 (FilmTec) for the recovery of caprolactam from an aqueous solution have been investigated. The experimental tests of the RO membrane were carried out using pure water (permeate from a nanofiltration system), brackish water (2000 ppm NaCl) and caprolactam solution (1000 ppm) and...
متن کاملBiofouling: lessons from nature.
Biofouling is generally undesirable for many applications. An overview of the medical, marine and industrial fields susceptible to fouling is presented. Two types of fouling include biofouling from organism colonization and inorganic fouling from non-living particles. Nature offers many solutions to control fouling through various physical and chemical control mechanisms. Examples include low d...
متن کاملSYMPOSIUM Barnacles and Biofouling
Synopsis Biofouling, the attachment and growth of organisms on submerged, man-made surfaces, has plagued ship operators for at least 2500 years. Accumulation of biofouling, including barnacles and other sessile marine invertebrates, increases the frictional resistance of ships’ hulls, resulting in an increase in power and in fuel consumption required to make speed. Scientists and engineers reco...
