Effect of Ultra-filtration Membrane Aperture on Storage Stability and Flavor of Bottled Huangjiu

open access: yesShipin gongye ke-ji
During the storage and sale of bottled huangjiu, precipitation caused by non-biological factors frequently compromises consumer acceptance. Ultrafiltration has been widely used to control huangjiu's non-biological stability, but this treatment's impact ...

Fouling Characteristics of Dissolved Organic Matter in Papermaking Process Water on Polyethersulfone Ultrafiltration Membranes

open access: yesBioResources, 2015
In the papermaking industry, closure of process water (whitewater) circuits has been used to reduce fresh water consumption. Membrane separation technology has potential for use in treating process water for recirculation.

Relationship of Dye Adsorption Onto Biomass Activated Carbon Mixed Matrix Ultrafiltration: A Mass Transfer Model Study

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explored dye molecule adsorption from water, focusing on activated carbon in polymer membranes for purifying low‐quality water. Polyvinylidene fluoride (PVDF) membranes showed enhanced removal efficiency of methylene blue (MB) from 89.29% to 98.33% with biomass‐activated carbon (BAC).

PREPARATION AND CHARACTERISTICS OF A PAPER-BASED ULTRAFILTRATION MEMBRANE

open access: yesBioResources, 2011
A novel process involving a paper-based ultrafiltration (UF) membrane was developed via paper coating technology. The membrane employed a paper sheet as support layer and a coated thin film layer of adhesive.

Low fouling conditions in dead-end filtration: Evidence for a critical filtered volume and interpretation using critical osmotic pressure [PDF]

open access: yes, 2005
This paper presents experiments showing the existence of a critical filtered volume (CFV) when operating colloid dead-end filtration. The CFV is here defined as the filtered volume below which there is no irreversible (with respect to a break in the ...

Characterization of Ultrafiltration Membranes [PDF]

open access: yesPolymer Journal, 1991
Transport phenomena, that are relevant to ultrafiltration membranes, are discussed. Their basic characteristics are given by the pore-flow theory. In actual applications, however, their behaviors are controlled by gel layer formation, osmotic pressure of solutes, adsorption or plugging in pores and by other chemical and physical natures of membranes ...

Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

A Model for Transport Phenomena in a Cross-Flow Ultrafiltration Module with Microchannels

open access: yesMembranes, 2010
Cross-flow ultrafiltration of macromolecular solutions in a module with microchannels is expected to have the advantages of fast diffusion from the membrane surface and a high ratio of membrane surface area to feed liquid volume.
