The performance (i.e., water flux and solute rejection) of a thin-film composite aromatic polyamide nanofiltration membrane its relation to surface charge (electrokinetic) characteristics were investigated. Membrane streaming potential measurements carried out as function pH for several solution chemistries, including an indifferent electrolyte, humic acid, anionic cationic surfactants. Performance results the interpreted by relating salt/ion rejection characteristics. In case electrolyte...
Growing demands for potable water have strained resources and increased interest in wastewater reclamation reuse. This has brought attention to endocrine-disrupting chemicals (EDCs) as emerging contaminants. The effect of EDCs, particular natural steroid hormones, on humans is heightened the study reuse advanced life support systems (e.g., space missions) because they are excreted urine high potencies. Direct contact membrane distillation (DCMD) forward osmosis (FO) being investigated...
A pilot system was designed and constructed to evaluate reverse osmosis (RO) energy reduction that can be achieved using pressure-retarded (PRO). The RO-PRO experimental is the first known utilize from a volume of water transferred atmospheric pressure elevated across semipermeable membrane prepressurize RO feedwater. In other words, demonstrated could exchanged between PRO subsystems. Additionally, power density data for now available. Average densities ranged 1.1 2.3 W/m2. This higher than...
Initiated chemical vapor deposition (iCVD) was used to coat two porous substrates (hydrophilic cellulose acetate (CA) and hydrophobic polytetrafluoroethylene (PTFE)) with a cross-linked fluoropolymer improve membrane wetting resistance. The coated CA superhydrophobic symmetric. PTFE asymmetric, smaller pore size lower porosity on the top surface than bottom surface. Membrane performance tested in distillation experiments (1) high-salinity feed solution (2) surfactant-containing solution. In...
Theoretical predictions of interaction energies for several membrane–colloid pairs were made using the classical DLVO theory and an extended (XDLVO) approach. The XDLVO approach accounts acid-base (polar) interactions that are not considered in theory. For all membranecolloid studied, similar. However, inclusion resulted substantially different short-range (separation distance <10 nm) investigated. Predicted compared with atomic force microscopy (AFM) measurements. colloid probe technique...
