The intent of this paper was to review reverse osmosis and nanofiltration membrane plants located in five states. The plants selected address both inland and coastal designed facilities as well as various plants using nanofiltration membranes, brackish water membranes and low pressure energy efficient membrane processes. Discussions for each plant selected include plant location, water supply source, and selection of membrane type, projected operating pressures; permeate water quality projected, operating temperature, and projected power costs for the generic type of membrane used. Discussions include operational experience of the plant design to avoid scaling and fouling and address high organic laden well waters and limiting the organic fouling potential. The writer hopes to provide a better understanding to new plant engineers and facilitate “out of the box”thinking for future reverse osmosis and nanofiltration plant designs.
