Effects of feed and draw solution temperature and transmembrane temperature difference on the rejection of trace organic contaminants by forward osmosis
The effects of feed and draw solution temperature and transmembrane temperature difference on the rejection of 12 trace organic contaminants (TrOCs) by two forward osmosis (FO) membranes were investigated. The membrane structure parameter (S) and the reverse salt (NaCl) flux selectivity (RSFS) were constant over the temperature range of 20-40 1C, suggesting that within this range, the solution ...
متن کاملComprehensive bench- and pilot-scale investigation of trace organic compounds rejection by forward osmosis.
Forward osmosis (FO) is a membrane separation technology that has been studied in recent years for application in water treatment and desalination. It can best be utilized as an advanced pretreatment for desalination processes such as reverse osmosis (RO) and nanofiltration (NF) to protect the membranes from scaling and fouling. In the current study the rejection of trace organic compounds (TOr...
متن کاملRemoval of trace organic contaminants by the forward osmosis process
The rejection of trace organic contaminants (TrOCs) by an osmotically driven membrane filtration process was investigated. A set of 40 compounds representing major groups of TrOCs of concern was selected for this study. The rejection of the TrOCs by a commercial cellulose acetate asymmetric forward osmosis membrane, as well as a ''tight'' commercial thin-film composite nanofiltration (NF) membr...
متن کاملRejection of trace organic compounds by forward osmosis membranes: a literature review.
To meet surging water demands, water reuse is being sought as an alternative to traditional water resources. However, contamination of water resources by trace organic compounds (TOrCs), including pharmaceuticals, personal care products, disinfection byproducts, and industrial chemicals is of increasing concern. These compounds are not readily removed by conventional water treatment processes a...
متن کاملMicroalgae (Scenedesmus obliquus) dewatering using forward osmosis membrane: Influence of draw solution chemistry
Article history: Received 9 October 2015 Received in revised form 8 December 2015 Accepted 22 January 2016 Available online xxxx Forward osmosis (FO) is gaining increasing interests for its potential applications in biofuel generation. In this study, bench-scale experiments were conducted to investigate the FO performance for microalgae dewatering which is one of the technical challenges in alg...
