Abstract
In recent years, the use of reverse osmosis (RO) membranes in advanced wastewater reclamation has been extensively applied. The treated secondary wastewater effluent, which is the feed source for reclamation process, contains a considerable amount of divalent cations (i.e., Ca2+, Mg2+) and dissolved organic macromolecules. The presence of divalent cations has been reported to form scales with various anions and complex macromolecules with the constituents of dissolved organic matters, which are having significantly adhesive properties to membrane surface. In our study, the effects of feed solution chemistry (species of cations and anions, pH) and dissolved organic composition on the adhesion of biochemically formed complex macromolecules and chemical scales to RO membrane surfaces were specifically investigated.
