Filtration membrane fouling index measuring method
A filtration membrane fouling index measuring method including: (a) serially connecting two filtration membranes having the same membrane properties, and sequentially passing influent water therethrough; (b) measuring the flow volume that has passed through the first of the filtration membranes; (c) measuring the flow volume that has passed through the second of the filtration membranes; (d) measuring the cumulative pass-through volume that has passed through the first or the second filtration membrane; and (e) determining the fouling index of the filtration membrane, based on the flow volume that has passed through the first filtration membrane, the flow volume that has passed through the second filtration membrane and the cumulative pass-through volume. The method eliminates pore-blocking-induced measurement errors that occur with measurement methods involving Modified Fouling Index which is a fouling index for filtration membranes.
