Bio-polymer modified nanoclay embedded forward osmosis membranes with enhanced desalination performance

The substrate of forward osmosis (FO) thin-film composite (TFC) membranes supports the formation of the selective layer. It can remarkably influence the structure as well as the physiochemical characteristics of the selective layer formed atop. Therefore, the improvement of TFC substrates in terms o...
