新しい型式のエア・フィルターについて

概要

Pressure drop of air flow and collection efficiency of bacterial particles through a specific plate filter were studied. A remarkably high collection efficiency with less pressure drop was obtained. The experimental results were compared with the performance of a fibrous glass filter which is extensively employed in the fermentation industry. The comparison, with reference to the field data of the plate filter, predicts a possibility that the plate made from polyvinyl alcohol could be applied in the fermentation industry. If the fibrous air sterilization filter is replaced by the plate filter, the size of the current device will be reduced tremendously with economy of construction as well as maintenance costs. However, the mechanism which accounts for the excellent performance of the plate filter if left open for further experimentation and theoretical discussion.
