✦ Synopsis
The pretreatment of raw seawater is necessary to reduce the fouling of reverse osmosis membranes and increase run length. To measure the plugging potential of pretreated feedwater, the modified fouling index was tested using both control suspensions and pretreated seawater. The defining equation was found to adequately describe the process. By distinguishing between the various filtration mechanisms, the modified fouling index was found to be more precise than other plugging indexes. A scheme is presented for the in situ, computer controlled measurement of the modified fouling index.
