Membrane-based gas transfer: an environmental engineering laboratory


, : Membrane-based gas transfer: an environmental engineering laboratory. Water Science and Technology 49(8): 49-56

We propose an educational experience in which students design a membrane gas transfer reactor, construct a bench-scale version in the laboratory, and employ the reactor to measure mass transfer coefficients. The membrane reactor is useful for teaching mass transfer principles because the mass transfer interface is well defined and easily observed. The system can be modeled successfully using straightforward mathematics. The reactor can be designed and constructed by students, using the mathematical model as a basis, providing insight into the physical meaning of model parameters. The proposed membrane system can be readily operated to obtain data that can be employed to develop or modify existing mass transfer correlations. This can provide students with significant insight into the development of mass transfer correlations and how the constants in such correlations are typically determined. These features help promote a deeper understanding of mass transfer principles.

Two new species of the genus Hypoglossum Kutzing (Delesseriaceae, Rhodophyta) are described: H. androlamellare sp. nov. from Zanzibar Island, Tanzania, and H. annae sp. nov. from the Malay Archipelago. The former is the first species of Hypoglossu...

Sister chromatid exchange (SCE) is a sensitive indicator of genotoxicity. In this study we investigated the effects of alcohol consumption and cigarette smoking on the frequency of SCE in cultures of peripheral lymphocytes. The rate was higher in...
