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.

In this paper, a seawater reverse osmosis desalination plant with various energy recovery systems is studied using exergy analysis. These energy recovery devices include turbines and pressure exchangers as well as infinite area based single and two-stage pressure retarded osmosis units. The appropria

• Very thin poly(vinyl alcohol) membranes supported on polysulfone hollow fiber • A controlled coating method for top membrane layer of uniform thickness • Composite hollow fiber membranes having top-layer-thickness of 0.1–1 μm • Best membrane performance so far in pervaporation desalination of saline

• New method for Li recovery from seawater is proposed using the world-first dialysis. • Li ionic superconductor as the Li separation membrane (LISM) was used. • Only Li ions can permeate the LISM. • The Li recovery ratios to approximately 7% after 72 h with no electrical supply. • Li separation proc

Membrane distillation (MD) is a hybrid thermal-membrane desalination process that uses low-grade waste heat and hydrophobic membrane to produce high quality distillate. The MD process can treat highly saline brines that other conventional desalination processes cannot treat. These unique features of

This article discusses the available alternatives for ocean concentrate disposal, site specific factors involved in the selection of the most viable alternative for a given project, and the environmental permitting requirements and studies associated with their implementation. The article focuses on

The main purpose of this study is to evaluate a combined ozone and microfiltration (MF) membrane process as pre-treatment of a seawater reverse osmosis (SWRO) system. During the filtration of seawater (SW) with the MF membranes, membrane fouling on both hydrophilic (PHI) and hydrophobic (PHO) MF mem

The CSIRO Flagship Cluster project Advanced Membrane Technologies for Water Treatment is a collaboration of nine Australian Universities and the CSIRO looking at improving the energy efficiency of desalination of seawater using membrane processes. One of the initial aims of the cluster is to develop

In order to determine the suitability of an ultrafiltration membrane module (OmexellTM SFP2660) to different feed waters, the filtrate quality and the operation status of the module were studied comparatively when it was fed with raw seawater, coagulated seawater and cooling tower blowdown (CTB) res

As a means of optimizing desalination processes, site-specificity in the determination of seawater quality conditions is a crucial point for improving the overall energy efficiency of a seawater reverse osmosis (SWRO) process. To this end, field studies were carried out at 16 sampling sites along th
