This work deals with thin film composite membranes prepared from m-phenylenediamine and 1,3,5benzenetricarbonyl chloride by interfacial polymerization on the surface of a polysulfone substrate, and graphene oxide was embedded into the membrane during membrane formation to improve the membrane perform

This paper introduces a hybrid desalination system coupled with nano-fluid solar heater for small scale needs. The hybrid desalination system consisting of a two stagehumidification–dehumidification unit and single stage flashing evaporation unit (MSH–SSF) configured by a (Al2O3/H2O) nano-fluid solar wate

This paper aims to investigate the different parameters that affect solar still productivity when the solar still productivity is very low compared with other desalination systems, such as other thermal processes or membrane processes. These parameters include environmental, design and operational p

To study the effects of ethylene oxide (EO) number in alkyl ethoxy carboxylates (AEC) on scale inhibition, ten AEC compounds are prepared. The effect of EO number on the scale inhibition against CaCO3, CaSO4 and Ca3(PO4)2 scales and effects of the operating conditions on scale inhibition against CaC

Reverse osmosis (RO) biofouling is a problem of biofilm development which is initiated by bacterial attachment to the membrane surface following the surface conditioning. In this study, the impact of the initial fouling layers on bacterial attachment was investigated. Both model foulants and MBR perm

• Dense ZIF membranes are prepared through bio-inspired polydopamine modification. • ZIF membranes are developed for the first time for seawater desalination. • The ZIF membranes show high water flux and ion rejection for seawater desalination. In conclusion, in the present work we have successfully de

• Balancing leads to 50% higher GOR than equal inlet flow rates in DCMD. • DCMD balancing achieved by setting heat capacity rate ratio to one at end • Proposed method deviates by about 5% from absolute maximum GOR at high salinity. • Real-time balancing most useful for variations in inlet salinity 1.

• A facility-scale simulation model for the power production of non-ideal river-tosea PRO was developed. • The model was linked to an optimization package to determine the system variables that produce a maximum net power for the facility. • Energy requirements of the components external to the PRO

• Simulation and sensitivity analysis of integrated SWRO-PRO system configurations for eliminating brine post-treatment step. • Identification of energy efficient novel SWRO - PRO hybrid desalination process for reducing the SWRO pre-treatment cost. • Method for optimization of hybrid SWRO-PRO system d

Fouling and scaling is one of the major challenges in membrane distillation process. This study investigates the utilizing of thermal rejected brine produced from multi-stage flash distillation (MSF) to minimize fouling and scaling on membranes in direct contact membrane distillation (DCMD) settings.
