Implementing CCDTM Reverse Osmosis to Minimize Water Footprint
This presentation provides a general overview of the water issues surrounding the southwestern United States and sustainable measures that can be implemented to reuse valuable wastewater resources for agriculture and indirect potable reuse applications. As the growing population of the southwest moves inland, the need for maximizing water resources...
Permeate Recovery and Flux Maximization in Semi-batch Reverse Osmosis
This paper considers process designs and projected membrane performance of semi-batch reverse osmosis (RO) systems for a range of brackish and low-salinity source water types and compositions. The potential advantages of new process design features that are attainable with batch RO but not practical for conventional RO, such as short membrane arra...
Concentrate Volume Minimization Utilizing Closed Circuit Reverse Osmosis
Closed Circuit Reverse Osmosis (CCRO) has demonstrated itself in a variety of environments and industries to provide a host of benefits including minimizing concentrate volumes. A concise introduction to the flexible CCRO process interlaced with explanation as to how maximum recoveries are achieved while minimizing the inefficiences related to tra...
Closed Circuit Reverse Osmosis (CCRO)
The mass adoption of a newly emerging Closed Circuit Reverse Osmosis (CCRO) technology across multiple industries represents one of the most fundamental breakthroughs in reverse osmosis since its commercialization in the 1960?s. The simple solution combines the benefits of dead-end filtration with the strengths of crossflow filtration. Using stan...
PFAs Rejection by NF and RO as a Function of Speciation, Membrane Characteristics and Recovery
Academic research on the use of flat-sheet coupons of NF and RO membranes at bench scale for removal of PFAS dates back to 2006. Tang et. al (2006) investigated removal of perfluorooctanesulfonate (PFOS) by four RO membranes (BW30, LFC3, ESPA3 and SG). PFOS passage through these membranes at feed concentrations ranging from 1 to 1,500 ppm was, in n...
