the negatively charged colloids in water. Fouling by aluminum-based colloid carryover can occur, with alert levels for the RO designer ranging from 0.1 to 1.0 ppm aluminum in the feed water. Aluminum chemistry is complicated by the fact that it is amphoteric. Aluminum at low pH’s can exist as a positively charged trivalent
