Journal ArticleDOI

Reduction of hexa-valent chromium with zero-valent iron: Batch kinetic studies and rate model

TL;DR: In this paper, a kinetic model that takes into account the direct reduction, the passivation process and the resultant decline of the active surface area of reaction is proposed, and the model parameters have been estimated by global optimization at each of the pH values.
Journal ArticleDOI

Simulation of continuous stirred rotating disk-membrane module: An approach based on surface renewal theory

TL;DR: In this article, a surface renewal model has been developed describing the aspects of mass transfer in a rotating disk-membrane (RDM) ultrafiltration cell, which takes into consideration of two distribution functions of random surface elements, one with respect to their point of origin and the other related to the corresponding residence time on the membrane surface.
Journal ArticleDOI

Adsorptive Mass Transport of Dye on Rice Husk Ash

TL;DR: In this paper, the effective pore diffusivities of the dye molecules studied in RHA were determined by a suitable global optimization technique, and the depth of penetration, on the other hand, has been estimated for various initial concentrations of dyes.
Journal ArticleDOI

Performance characterization and CFD analysis of a novel shear enhanced membrane module in ultrafiltration of Bovine Serum Albumin (BSA)

TL;DR: In this article, a shear enhanced spinning basket membrane (SBM) module has been presented, which is unique in terms of its hydrodynamic cleaning facility, considering its structural similarity with the well known spinning basket reactor.
Journal ArticleDOI

Proposed Adsorption–Diffusion Model for Characterizing Chromium(VI) Removal Using Dried Water Hyacinth Roots

TL;DR: In this article, the effective pore diffusivity of chromium(VI) in the water hyacinth roots is determined by a suitable global optimization technique, and the depth of penetration, on the other hand, has been estimated.
