Ionosilica nanoparticles are original ionic nano-objects at the interface of liquids and mesoporous silica. nanoparticles' synthesis was achieved via sol-gel procedures exclusively from trialkoxysilylated precursors without any silica source. However, knowledge about main parameters for a controlled ionosilica remained fragmental so far. In this work, we present systematic study nanoparticle fo...

Microalgae shows a high potential to produce biofuel and forward osmosis (FO) has been proposed as promising dewatering process for algal biomass separation from water. However, the effect of reverse salt flux (RSF) on during using FO not completely explored. This study was investigate different types their concentrations in terms conductivity, settling velocity, lipid contents FS simulated FO-...

In the current lab scale study, two treatment technologies of FO (Forward osmosis) and DCMD (Direct contact membrane distillation) were used in combination to create a continuous system for water reclamation using, inorganic NaCl, surfactant (Tetraethyl ammonium bromide, TEAB) polyelectrolyte (Polydiallyldimethylammonium chloride, PDAC) as draw solutes with both DI (FO-MD), monoculture municipa...

Waste activated sludge (WAS) treatment has gained growing interests for its increasingly capacity and high process cost. Sludge thickening is generally the first of WAS treatment. However, traditional approach was restrained by large footprint, low efficiency, tendency releasing phosphorus. Here, we reported a novel microfiltration (MF) membrane assisting forward osmosis (FO) (MF-FO) thickening...

In this study, a novel integrated forward osmosis - membrane distillation (FO-MD) module equipped with an isolation barrier carefully placed between the FO and MD membranes is experimentally investigated, its performance compared conventional hybrid module. The function of to osmotically thermally separate draw solution (DS) feed channels. A systematic approach adopted compare flux through both...

The feasibility of bilayer polymer hydrogels as draw agent in forward osmosis process has been investigated. The dual-functionality hydrogels consist of a water-absorptive layer (particles of a copolymer of sodium acrylate and N-isopropylacrylamide) to provide osmotic pressure, and a dewatering layer (particles of N-isopropylacrylamide) to allow the ready release of the water absorbed during th...

Fouling behavior along the length of membrane module was systematically investigated by performing simple modeling and lab-scale experiments of forward osmosis (FO) membrane process. The flux distribution model developed in this study showed a good agreement with experimental results, validating the robustness of the model. This model demonstrated, as expected, that the permeate flux decreased ...
