Modeling of transitional pore blockage to cake filtration and modified fouling index – Dynamical surface phenomena in membrane filtration

摘要: Abstract The objective of this study was to optimize and model the membrane fouling process. modeling based on two approaches, dynamical phenomenological with combination surface phenomena. established a transitional pore blockage towards cake through new characteristic parameters modified index. developed in described effect restructuring, shear, mass cake, filtered fluid recirculation according effective thickness Z c mechanism. Modified index – Dynamical phenomena (MFI- DSP) by characteristics multiple interactions forces ratio mechanical transition regime. carried out compressibility factor m = 1, n = [0–1] kinetics process corresponding partial orders ω = [0–4]. validated experimental data tangential frontal filtration, using PES-10, UE-100 NF-270 membranes prediction blockage. Statistical analyzes at CI ≥ 95% showed better performance efficiency compared existing models focused absolute relative error, correlation coefficient, number prediction, characterization process, as well from filtration.
