The transport properties of cellulose acetate membranes have limitations due to polymer impurities that may restrict flow and/or act as sites for salt leakage. Under the conditions found in this study, a novel technique was developed to obtain an image of these impurities. These impurities can be determined semi-quantitatively per unit area, and co...

This paper describes work done by the US Bureau of Reclamation to produce Cellulose Acetate membrane that is naturally chlorine resistant allowing for easier biofouling control and are a better option than Polyamide membranes for waters with high organic particulate fouling potential....

Recycled water projects that include some form of potable reuse are becoming more common in the water industry. They are being built to help alleviate water shortages throughout the world by allowing the reuse of available water. Many of these systems utilize membrane processes to remove soluble and insoluble contaminants to produce high quality pr...

Cal Poly Pomona, Carollo Engineers, Inc., and Pall Corp. are participating in a water reuse research funded by Bureau of Reclamation to evaluate novel treatment train ?integrated membrane anaerobic stabilization (IMANS)? system for wastewater treatment and water reclamation, the performance of microfiltration (MF) and reverse osmosis (RO) of primar...

The USBR conducts and/or sponsors a long list of water supply and treatment research programs, including many university and post-doc fellowships. USBR's membrane oriented research projects are described in the presentation....
