Microfiltration

The integrated system with microfiltration/electrodialysis was proposed for wastewater reclamation. The filterability of metal membrane, membrane fouling reduction by ozonated water and the effect of operational parameters were experimentally investigated. Backwashing by ozonated water showed stable

A bench scale submerged microfiltration system coupled with high concentration of PAC (powdered activated carbon) was applied in order to purify a river water containing secondary effluent. The system was operated with four different modes: Run-1, -2, -3 and -4. The PAC concentration was set at 0, 4

The ceramic microfiltration system with periodic N2-back-flushing was operated for treating paper wastewater discharged from a company making toilet papers by recycling milk or juice cartons. Two kinds of alumina membranes with 7 channels used here for recycling paper wastewater. The optimal N2 filt

The objective of this study is to evaluate the effect of electric fields application for the reduction of membrane fouling, the inactivation of microorganisms and the enhancement of particle coagulation. It was found that electric fields treatment prior to microfiltration showed in large quantity of

The anion exchange membranes had high rejection of the gold sols with flux three times greater than those of GVWP, whereas the cation exchange membranes and GVWP showed little capture as expected. The increase in pressure decreased the rejection rate of the gold sols indicating that residence time a

The results of studies are presented on the treatment of natural waters with a high content of organic compounds. The research involved unit processes of coagulation, microfiltration, and the hybrid process coagulation– sedimentation–microfiltration. In the membrane filtration process 19-channnel ce

Ultrathin alumina hollow fibers were prepared by a phase inversion and a sintering method. A polysulfone solution containing well-dispersed alumina powders is spun, which is then sintered at elevated temperature. To increase the packing density of alumina powers in the hollow fiber, 1,4-dioxane was

The present study investigates the respective impact of dissolved constituents in the fermentation, suspended solids, and particles on the purification of fermentation broth by an electro-microfiltration membrane process. Microfiltration by these constituents induced sharp initial flux declines, the

Microfiltration of rigid spherical particle suspension in a hollow fiber module operating with inside–out flow, at a constant module inlet flow rate, was simulated using the shear-induced hydrodynamic diffusion model of Mondor and Moresoli, with consideration of the axial variation of the pressure d

In this paper, the effect of operation parameters of microfiltration (MF) and ultrafiltration (UF) processes on the performance of purification and de-colorization of raw juice have been studied. Experiments were carried out using the pilot plant MF/UF membrane system equipped to a tubular module wi
