This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot. The operating conditions of the treatment process, including pH, FeCl3 dose, and influent flow, were investigated. Following that, its efficienc...

Flow in porous Silicon Carbide (SiC) has been investigated in order to increase the understanding of the determining parameters. Porous SiC is used in the fabrication of ceramic membranes, for use in cross-flow and dead-end filtration. Therefore, a description of the flow would help to design more efficient filtration modules, and to improve the use of the existing modules. The investigation pe...

PURPOSE Membrane-based Tangential Flow Filtration (TFF) unit operations are used for clarifying, concentrating, and purifying proteins. This technical brief is a practical introduction to protein processing using tangential flow filtration. It is intended to help scientists and engineers achieve their protein processing objectives by discussing how the choice of key components and operating par...

Membrane filtration is a vital industrial process, with applications including air purification and blood filtration. In this paper, we study the optimal design for concertinaed membrane composed of angled porous membranes dead-ends. We examine how filter performance depends on angle, position, thickness, permeance membrane, through combination numerical asymptotic approaches, latter in limit s...

Micropuncture techniques were used to evaluate the determinants of glomerular filtration in hydropenic dogs. Stop-flow and servo-null techniques were used to estimate the glomerular capillary and proximal tubule hydrostatic pressures. The validity of stop-flow estimates was verified by comparisons with direct puncture of glomerular capillaries in Munich-Wistar rats. Efferent arteriolar oncotic ...

Prediction of pore fouling by microparticles is still challenging and remains a difficult step to optimize membrane and filtration processes. The scientific issue consists in determining the relevant operation parameters controlling the capture of particles and the clogging of the filter. In this study, we have developed for a dead-end and cross-flow filtration a poly-dimethylsiloxane (PDMS) de...
