Development of low-biofouling polypropylene feedspacers for reverse osmosis

Nitric oxide treatment for the control of reverse osmosis membrane biofouling.

Biofouling remains a key challenge for membrane-based water treatment systems. This study investigated the dispersal potential of the nitric oxide (NO) donor compound, PROLI NONOate, on single- and mixed-species biofilms formed by bacteria isolated from industrial membrane bioreactor and reverse osmosis (RO) membranes. The potential of PROLI NONOate to control RO membrane biofouling was also ex...

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...

Biofouling in reverse osmosis processes: the roles of flux, crossflow velocity and concentration polarization in biofilm development

Composition and variability of biofouling organisms in seawater reverse osmosis desalination plants.

Seawater reverse osmosis (SWRO) membrane biofouling remains a common challenge in the desalination industry, but the marine bacterial community that causes membrane fouling is poorly understood. Microbial communities at different stages of treatment processes (intake, cartridge filtration, and SWRO) of a desalination pilot plant were examined by both culture-based and culture-independent approa...

A Novel Photovoltaic Powered Reverse Osmosis with Improved Productivity of Reverse Osmosis and Photovoltaic Panel

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...
