Operating conditions

We systematically evaluated the effects of operating conditions on biofouling behaviors in reverse osmosis (RO) membrane processes. The biofouling experiment was performed by filtrating nutrient-containing feed water with a cross-flow cylindrical membrane cell through a circular polyamide RO membrane

Desalination via pervaporation has the potential to be an efficient way of getting fresh water from non-potable saline sources with the advantages of a high rejection of salt and the capability of coping with high-salinity solutions. This overview of desalination via pervaporation mainly focuses on m

This work presents a systematic evaluation of the membrane and process characteristics of a scaled-up pressure retarded osmosis (PRO). In order to meet pre-defined membrane economic viability (≥5 W/m2), different operating conditions and design parameters are studied with respect to the increase of t

The removal of arsenic from synthetic waters and surface water by nanofiltration (NF) membrane was investigated. In synthetic solutions, arsenic rejection experiments included variation of arsenic retentate concentration, transmembrane pressure, crossflow velocity and temperature. Arsenic rejection

A mathematical model for the simulation of ultrafiltration process has been developed in this study. Ultrafiltration tests were carried out on an aqueous solution of lignosulphonate — a natural polymer — employing a pilot-scale ultrafiltration configuration that accommodates spiral wound membranes.

An investigation of wastewater treatment by ultrafiltration (UF) is introduced. In the experiments a UF membrane (UFPHT20-6338) and samples of Behshahr Ind. Co. wastewater as feed were used. The effect of operating conditions such as pressure difference, cross flow velocity, shear stress, temperatur
