• 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

Forward osmosis (FO) has recently attracted growing attention in wastewater, brackish groundwater and seawater desalination, and power generation. This study evaluates the potential of using a batch laboratory-scale FO system as a pre-treatment for the reverse osmosis (RO) process. FO is a low press

Biopiles are a common treatment worldwide for the ex-situ remediation of contaminated soil. Much research has been carried out on understanding and modelling microbial degradation, but hitherto no study has attempted to model the effect on a biopile of its ambient surroundings. This paper presents a

The vegetable sponge of cylindrical loofa, a natural product which grows in the north of Algeria, was used for phenol removal from wastewater. Adsorption isotherm of phenol onto the prepared cords of loofa was determined by batch tests. The effects of various parameters such as contact time, initial

The leaf sheath fibres of the Mediterranean seagrass Posidonia oceanica (L.) were used as low cost, available and renewable biological adsorbent for the removal of a metal complex textile dye from aqueous solutions. Batch experiments were carried out for sorption kinetics and isotherms. Operating va

In this work, the membrane technique of nanofiltration (NF) was used to carry out partial demineralization of whey and milk ultrafiltration permeate (MUP). The experiments were performed in a completely automated NF pilot plant. An aromatic polyamide spiral wound membrane supplied by Osmonics (USA)

In this work, modelling of a submerged membrane bioreactor (SMBR) system for municipal wastewater treatment is evaluated using ASM1 and ASM3 models. Dynamic data (and pseudo steady state) collected in an aerobic SMBR working at high sludge retention time (SRT) are considered. Work is focused on susp

Pervaporation, a membrane technology requiring low energetic demands, is considered to substitute the conventional distillation unit employed in the beverage industry in order to recover the key aroma compounds, and that would avoid the damages to the quality of the flavour profile. The analysis of

The aim of this paper is to model and optimize the conditions of obtaining the activated carbon prepared from the date cores, and the elimination of phenol by adsorption. Several activation chemical agents were tested for the preparation of the activated carbon. Best results is obtained with the pho

Recently, computational fluid dynamics (CFD) models of flows in membrane channels have been proposed and validated against published simplified models available in the literature. In this paper, experimental and numerical analysis is performed for a reverse osmosis (RO) module and results compared i
