The characteristic parameters of pressure retarded osmosis (PRO) membranes (water permeability, A, solute permeability, B, and the structural parameter of the membrane support layer, S) were estimated by a single PRO test combined with a statistical approach. The single PRO test measures water and r

Hydraulic turbocharger is a common energy recovery device used in reverse osmosis water desalination plants to recover the stored energy in brine. Also, it can be used to control the pressure variation due to the change of plant operating conditions. The aim of the current work is to apply the compu

• Direct UF–RO integration was implemented through an advanced control scheme. • RO concentrate stream was utilized for UF backwash. • Pulse backwash significantly improved overall UF backwash effectiveness. • Self-adaptive UF backwash successfully retarded the progression of UF fouling. A novel RO d

Biofouling and scaling are commonly encountered bottlenecks in large and small scale installations of membrane technology for surface-, waste- or seawater treatment. The phenomena can pose persistent operational challenge with substantial economic impacts if they are left unresolved. Effort has been

Multidisciplinary, innovative and high values development of high performance, cost-effective and environmentally acceptable separation systems is highly desired to tackle the sustainability challenges that facing current desalination technology. Owing to their versatility and immense potentials to

This paper investigates the annual performance of multi-effect desalination plant combined with a thermocompressor MED–TC driven by a solar steam generation plant. The desalination model is coupled with solar steam generation plant model to supply the necessary thermal energy to drive the desalinati

• Modifications of support layer were conducted using a commercial PTFE/PP bi-composite membrane. • Macro punctures of support layer were designed based on the porosity of the support layer. • Porosity of support layer and sizes of macro punctures affected the fluxes of the modified membranes. • The or

• Adsorption/fouling-layer model analyzes the flux decline during RO filtration. • The model provided a qualitative appreciation of the flux decline. • The factors of filtration time and membrane flux are considered in the fouling model. • The main interfacial interaction in each fouling step was discuss

This study demonstrates how seawater reverse osmosis (SWRO) plants, necessary to meet increasing future global water demand, can be powered solely through renewable energy. Hybrid PV–wind–battery and power-to-gas (PtG) power plants allow for optimal utilisation of the installed desalination capacity

Large-scale Li-ion doped graphene/carbon nanofiber porous architectures were prepared by electrospinning homogeneous LiNO3/graphene oxide/polyacrylonitrile nanofibers, followed by carbonization at 900 °C. Capacitive de-ionization was measured in a dynamic mode. The architectures show excellent electri
