Tóm tắt

For membrane processes, pumping usually costs most.In classical Rayflow filtration, operating conditions must be optimized to limit membrane clogging. In this article, we study the use of dynamic filtration, where the shear rate is independent of the feed rate, as an interesting alternative to achieve flow and high final concentrations and reduction of energy cost from pumping. The tests were carried out in standard Ray flow filtration under similar operating conditions. Conventional tangential filtration assays, micro filtration(PES0,05microns) or ultra filtration (40 kDaPAN), show a constant and linear reduction of the flow and the ability to reach maximum concentrations of microalgae of about 90g/L.
