Ceramic−carbonate dual-phase membranes have attracted a lot of attention because of the emission of CO2 and environmental problems. In this study, a dense SrFe0.8Nb0.2O3−δ−carbonate dual-phase multichannel hollow fiber membrane has been successfully prepared via a phase inversion−sintering technique and impregnation. The morphology, crystal structure, phase stability, breaking load, and CO2 per...
Take the ethylene-vinyl alcohol (EVAL) copolymer as the infrastructural material, the anion exchange resin D301R as the functional grains, adopt dry-wet method to make resin-filled EVAL hollow fiber membrane, test the pure water flux of the membrane, the rejection rate of the bovine serum albumin (BSA) and the static absorption performance of BSA. Check the influences of coagulation bath temper...
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can no longer meet requirements in terms of volume or quality, or the membrane simply breaks up (hollow fibers), and the system has to be shut dow...
A membrane biofilter is used to biodegrade toluene in the gas phase. Active microorganisms are immobilized on the outside of a hollow fiber membrane cartridge and air containing toluene as the contaminant is passed through the membrane fibers. A porous polysulfone membrane containing water in the pore is used through which both toluene and oxygen are diffused to the biofilm attached to the outs...
