Many reclamation treatments as well as integrated processes for the purification of olive mill wastewaters (OMW) have already been proposed and developed but not led to completely satisfactory results, principally due to complexity or cost-ineffectiveness. The olive oil industry in its current status, composed of little and dispersed factories, cannot stand such high costs. Moreover, these trea...

Forward osmosis (FO) requires a specific membrane structure for applications like juice concentration. The phase inversion method was used to make cellulose acetate (CA) FO membranes. solvents were acetone and 1,4-dioxane. Additives included polyvinylpyrrolidone (PVP), methanol, maleic acid in the preparation of CA membrane, which it easier improve membrane's permeability. performance fabricate...

Article history: Received 9 October 2015 Received in revised form 8 December 2015 Accepted 22 January 2016 Available online xxxx Forward osmosis (FO) is gaining increasing interests for its potential applications in biofuel generation. In this study, bench-scale experiments were conducted to investigate the FO performance for microalgae dewatering which is one of the technical challenges in alg...

Seawater desalination for agricultural irrigation will be an important contributor to satisfying growing water demands in water scarce regions. Irrigated agriculture for food production drives global water demands, which are expected to increase while available supplies are further diminished. Implementation of reverse osmosis, the current leading technology for seawater desalination, has been ...

The present work aims to study the possibility of utilization a forward osmosis desalination process as an alternative method extract water from brine solution rejected reverse process. Experiments conducted in laboratory–scale (FO) unit cross flow flat sheet membrane cell yielded flux ranging (0.0315 0.56 L/m2 .min) when using CTA membrane,and (0.419 2.785 for PA under 0.4 bar. Two possible or...

We have examined the gypsum (CaSO4·2H2O) scaling phenomena on membranes with different physicochemical properties in forward osmosis (FO) processes. Three hollow fiber membranes made of (1) cellulose acetate (CA), (2) polybenzimidazole (PBI)/polyethersulfone (PES) and (3) PBI-polyhedral oligomeric silsesquioxane (POSS)/polyacrylonitrile (PAN) were studied. For the first time in FO processes, we...
