Pressure driven inside feed (PDI) hollow fibre filtration: Optimizing the geometry and operating parameters

Dewatering of fibre suspensions by pressure filtration

Optimizing Hollow Fibre Nanofiltration for Organic Matter Rich Lake Water

Over the years, various technologies have been utilized for Natural Organic Matter (NOM) removal with varying degrees of success. Conventional treatment methods comprising of coagulation, flocculation, sedimentation, or filtration are widely used to remove NOM. An alternative to these conventional methods is to use spiral wound membranes. These membranes tend to remove too much hardness whilst ...

Separation of whole blood into plasma and red cells by using a hollow-fibre filtration system.

BACKGROUND AND OBJECTIVES The aim of this study was to assess the separation of whole blood into red cells and plasma by using the Sangofer device, which is a gravity-fed, hollow-fibre system. The components would then be compared with those produced by the use of more elaborate technical equipment. MATERIALS AND METHODS Ten whole-blood units were leucoreduced by using a WBF2 filter and immed...

Numerical investigation of effective harbor geometry parameters on sedimentation inside square harbors

Sedimentation is one of the most important problems in harbors that results in considerable economic costs. Harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. In the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...

Fouling of a hollow fibre submerged membrane during long- term filtration of activated sludge

Membrane fouling in membrane bioreactors (MBR) is caused by cake formation on the surface, mainly attributed to suspended solids, and also by surface adsorption connected with pore blocking, attributed to soluble components of activated sludge. In this study, long-term experiments were carried out in sub-critical conditions with frequent backwashing, and the nature of fouling was investigated. ...
