This presenation cover the upgrading of lime softening plants to membrane nanofiltration. Discussed are an overview of the two technologies, a comparison of their capabilities, the use of membranes and the cost to implement the change....

Paper compares reverse osmosis (RO) rejection of total dissolved solids (TDS) and boron for three high rejection membranes treating estuarial feed and evaluate the requirements for a partial second pass to meet permeate TDS and boron requirements to meet WHO guidelines. The evaluation also considers the impact of pH, recovery and feed water ion mix...

The focus of the technical paper and presentation will be the performance of the pretreatment systems, primarily in terms of turbidity and SDI performance indicators, and relative ability and robustness of the pretreatment systems to accommodate variations in seawater quality. Operational and analytical data will be presented of pretreatment system...

Implementation of low-pressure membrane systems requires many factors to be considered in order to have a successful design....

This powerpoint presentation addresses the future of membrane filtration and membrane separation technologies including the optimization of current technologies as well as new techniques and new materials on the horizon....

This talk summarizes the rapid growth of the use of MF and UF as pretreatment for seawater desalination. Cost, filtrate quality, operations, membrane materials all contribute to the increase in MF/UF for RO pretreatment on a world wide basis....
