Cross-Flow Filtration with Mixed Matrix Membranes for the Removal of Proteins from White Wines
… mixed matrix membranes (MMM) in cross-flow filtration systems. This process aims to reduce the processing time and reduce or eliminate the generation of bentonite lees. While protein adsorber membranes made using the wet phase inversion technique had been studied before, this …

Retention of fermentation biomass for extended L-Lysine fermentations
… stream is separated from the spent medium using cross-flow filtration. The objective of this thesis was to study, understand, model and optimise the performance of the L-Lysine fermentation with biomass retention using cross flow filtration. Following a review of the factors affecting cross-flow …

PVDF-graphene conductive composite membrane and PVA-graphene conductive composite membrane preparation and application
… prevent membrane blocking in dead-end electrical filtration. Based on calculation, if charged particles were held into electric field, at least 118 V must be used in dead-end electrical filtration. But with a cross flow filtration equipment, only 1 to 2 V was needed. Further research should be …

The marine biogeochemistry of dissolved and colloidal Iron
… the two most commonly utilized methods of sFe filtration were compared: cross flow filtration (CFF) and Anopore filtration. Both were found to be robust sFe collection methods, and sFe filtrate through CFF (10 kDa) was found to be only 74±21% of the sFe through Anopore (0.02μm) filters at 28 …

Effects of filtration process variables on filter cake properties and formation
… provide a better understanding of the effects of filtration variables on filter cake properties and formation. There are three main types of variables that affect filter cake properties: drilling fluid formulations, substrate properties, and operative parameters. The effect of these variables of …

The role of colloidal material in the fate and cycling of trace metals in estuarine and coastal waters
… molecular weight) fractions were separated by cross-flow filtration (CFF). Filtration artefacts (conventional and CFF) involving filter blockage and colloid aggregation/disaggregation transformations were minimised through appropriate protocols.65Zn equilibration experiments were carried out …

Purification of plasmid DNA for use in human gene therapy
… a preliminary purification procedure, an EFD cross-flow micro-filtration module was assessed for its ability to effect the 20-fold concentration, 6-time diafiltration, and final clarification of the plasmid DNA from the subsequent cell lysate that is derived from a 1 liter E.coli bacterial …
