The path for water molecules transported across a membrane in real porous membranes has been considered to be constant factor the distillation (MD) process (i.e., tortuosity); as such, its effect on performance at various operating conditions ignored by researchers. Therefore, simultaneous heat and mass transfer model throughout direct contact (DCMD) module was developed this study taking into account hypothetical variable within because it exhibits changes resistance under DCMD run....
The present study harnessed a commercially available polydimethylsiloxane (PDMSTM4060) membrane designed for the selective separation of soluble benzene (C6H6) and toluene (C7H8) compounds from an aqueous solution employing pervaporation (PV). Two distinct mathematical models, namely universal quasi-chemical (UNIQUAC) model conventional driving force model, were formulated to replicate intricate transport mechanisms both organic solvent water across these membranes. These models instrumental...
Direct contact membrane distillation (DCMD) offers an attractive operation for the separation of mixtures at atmospheric pressure with reasonable energy requirement.

The presence of organic compounds such as ciprofloxacin in untreated pharmaceutical wastewater often poses a serious health risk to human and aquatic life when discharged into water bodies. One the most effective means removing from is photocatalytic degradation. However, synthesis an photocatalyst that can degrade pollutant challenge. Hence, this study focuses on application nitrogen-doped TiO2 (N-TiO2) suspension coated forms for degradation by applying UV-light irradiation. was prepared...
Ring opening and recyclization reactions with 4-hydroxy-6-methyl-3-nitro-2 H -pyrano[3,2- c ]quinoline-2,5(6 )-dione (1) was examined towards some carbon nucleophilic reagents.
Vacuum membrane distillation (VMD) is a promising process for water desalination. However, it suffers some obstacles, such as fouling and wetting, due to the inadequate hydrophobicity of high vacuum pressure on permeate side. Therefore, improving surface roughness important. In this study, effect 1H,1H,2H,2H-Perfluorodecyltriethoxysilane (PFTES) morphology performance CNM/PAC/PVDF membranes at various concentrations was investigated first time. Membrane characteristics FTIR, XRD, FE-SEM,...
Abstract Poly(vinylidene fluoride‐ co ‐hexafluoropropylene) (PVDF‐ ‐HFP) hollow fiber membranes were prepared by using the phase inversion method.
