Combined Membrane Processes : Comparing of Dead-end and Cross-flow Modes

Original language description

This contribution deals with the study of process combining both cross-flow microfiltration and ionic exchange on zeolite A added to the feed stream. The experimental set-up for cross-flow microfiltration was used with ceramic tubular membrane, the nextset of measurements was carried out with dead-end hollow fiber microfiltration unit. It was found, that the permeate flux reduction was not significant, if we used powdered zeolite as an additive in cross-flow microfiltration. In contrast to this fact, granulated zeolite tendency for irreversible membrane fouling was rather high at permeate fluxes above 40 L/m2.hr, even if backflushing was used. The preliminary batch experiments were performed for the sorptive kinetics and the sorptive capacity determination. From these measurements the parameters of Langmuir and Freundlich isotherms were determined. A theoretical model for dynamic sorptive process prediction was suggested and verified ranging from batch experiment results.

Kombinované membránové procesy: Srovnání výsledků měření při dead-end a cross-flow uspořádání

Czech description

Příspěvek se zabývá studiem kombinavaného membránového procesu spojujícího mikrofiltraci a iontovou výměnu na A zeolitu. Byly provedeny předběžné experimenty pro stanovení sorpční kapacity a studium reakční kinetiky. Z těchto měření byly určeny parametryLangmuirovy a Freundlichovy izotermy. Dále byl navržen teoretický model pro předpověď chování dynamického systému.
