In this study, a dual-layer hollow fiber nanofiltration (NF) membrane was fabricated with an inner layer of poly(vinylidene fluoride) (PVDF) via thermally induced phase separation (TIPS), and an outer layer of cellulose diacetate (CA) via non-solvent induced phase separation (NIPS). The intermediate-tr

The aim of this study is to investigate analytically and experimentally the effect of using an induced atmospheric air, water heaters, external reflector and weather condition on the performance augmentation of humidification– dehumidification (HDH) system. This novel HDH system is a modified solar stil

In this paper, authors breakdown the specific energy consumption for seawater and brackish water desalination in an attempt to quantify the value of high permeability membranes on specific energy consumption for desalination. The trends from the analysis presented in this paper show that in both seawa

On-site treatment and reuse is an increasingly preferred option for produced water management in unconventional oil and gas extraction. This paper analyzes and compares the energetics of several desalination technologies at the high salinities and diverse compositions commonly encountered in produce

The growth in population and in the standard of living in the developing countries coupled with inefficient use of water and pollution of available water resources have driven desalination to be a major source of fresh water for both domestic and industrial purposes. The potential environmental impac

Although membranes are widely employed in separation processes, their performance can be severely deterred by fouling due to organic, inorganic and biological foulants. Periodic electrolysis is a fast and simple technique for membrane cleaning, but requires membranes with high electric conductivitie

• A model for water flux through a PRO membrane is developed. • A validated model for temperature distribution over the membrane is also provided. • The effect of the solution temperatures on the membrane properties was highlighted. • It is shown how raising the feed solution temperature enhances the

Theoretical and experimental studies of direct contact membrane distillation (DCMD) using commercially flat sheet hydrophobic polyvinylidene fluoride (PVDF) membrane were investigated to remove boron from simulated and natural seawater. Mass transfer mechanism and theoretical flux were determined using

Thermodynamic losses caused by the flow resistances and the boiling point elevation (BPE) in low-temperature multi-effect evaporation (LT-MEE) desalination plant were investigated. The purpose is to provide detailed considerations for the design and modeling of LT-MEE process. Design parameters were

In this paper, we focused our work on the direct contact membrane distillation (DCMD) capability to treat hypersaline solution. The governing operative model for mass transfer was investigated. The measured flux has been well predicted by the Knudsen-molecular mechanism model. The effects on the DCMD
