Direct contact membrane distillation (DCMD) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. DCMD is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...

Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...

In this study, the focus is on magnetic separation of fresh water algae Chlamydomonas reinhardtii and Chlorella vulgaris as well as marine algae Phaeodactylum tricornutum and Nannochloropsis salina by means of silica-coated magnetic particles. Due to their small size and low biomass concentrations, harvesting algae by conventional methods is often inefficient and cost-consuming. Magnetic separa...

Pressure-driven ultrafiltration membranes are important in separation applications. Advanced filtration membranes with high permeance and enhanced rejection must be developed to meet rising worldwide demand. Here we report nanostrand-channelled graphene oxide ultrafiltration membranes with a network of nanochannels with a narrow size distribution (3-5 nm) and superior separation performance. Th...

INTRODUCTION: Multi-contrast water-fat separation based on the Dixon method is steadily gaining importance in clinical routine. An accelerated examination using dedicated acquisition schemes in combination with an iterative reconstruction is therefore highly desirable. A direct reconstruction of water and fat images incorporating field inhomogeneities, relaxation effects as well as gradient del...

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

Introduction In the three-point Dixon water fat separation method, one in-phase echo and two out-of-phase echoes are sampled in Cartesian k-space trajectory conventionally [1][2]. The Cartesian sampling is sensitive to motions, such as from pulsation and flow, which cause artifacts degrading the image quality. To address this problem, a non Cartesian sampling method, TSE BLADE three-point Dixon...

Electrodialysis is an electrochemical membrane separation technique for ionic solutions that has been used in industry for several decades. It can be used in the separation and concentration of salts, acids, and bases from aqueous solutions, the separation of monovalent ions from multivalent ions, and the separation of ionic compounds from uncharged molecules. It can be used for either electrol...
