Kieselguhr filtration A presentation of modern filtration theories
For over 100 years, brewery technologists have been addressing the subject of beer filtration. In laboratory scale experiments, numerous investigations have been carried out on representation of filter pressure drops. The process described here makes it possible to determine the filter aid resistance in commercial filtrations, also without directly measuring the cake thickness.
Filtration, introduced in breweries almost exactly 100 years ago with the beginning of mass filtration, is closely connected with clarification as well as most other steps in the brewing process. Yet in early times, there were also those who were not exactly in favour of filtration.
Indeed, beer filtration is not a magic solution for rectifying mistakes in the preceding operations in beer production...
