Praktické aspekty měření kontaktních úhlů na povrchu filtračních přepážek

Abstract

This thesis deals with wettability of surfaces of technical textile from MITOP company. Wettability was tested on various levels of silting by filtration. As a silting medium was used sludge from treatment for drinking water. Filtration proceeded at constant temperature and pressure conditions. Every single tested sample, was silted at eight cycles, where one cycle mean filtration 5 ml of sludge. At ever cycles was taken measurement of the filtration time and turbidity of filtrate. Measurement was complemented about wetting angle on clean and gradually silted technical textile.
