Subsequent to a validation period of over six months, the Ecoflux KF1600/50 kieselguhr precoat filter was tested and evaluated by the State Testing and Evaluation Institute for Brewery Equipment of the Technical University of Munich in Weihenstephan. Optimal results were obtained in terms of operating cycle time, kieselguhr consumption, microbiology, haze and oxygen concentration in the filtrate, these results are discussed in this article.
A microbiological monitoring test of the new SeitzSchenk candle precoat filter KF1600/50 Ecoflux was carried out in a German brewery on November 30th, 1999. At the same time, pressure relationships, oxygen values, kiesel-guhr consumption as well as hazes measured from two different angles were checked. Klaus Litzenburger.

SeitzSchenk Filter Systems GmbH of Bad Kreuznach/Waldstetten in Germany have developed a new generation of candle filters to round off their product program. When used for beer filtration, these provide significant benefits in terms of ease of operation and economics. The first results are discussed in this article.
In the brewing industry, candle filters are, together with horizontal filters, one of the most common filtration systems for filtration of beer. These filters are used especially for pre-filtration as precoat filters, customarily using kieselguhr as a filter aid. SeitzSchenk Filter Systems GmbH, Bad Kreuznach/Waldstetten in Germany, have developed a new generation of candle filters to round off their product program.

In the context of the thesis of Marx (1), particle count as well as particle distribution were measured online in seven large breweries in Germany during beer filtration, using the new PCS 2000 particle counting system from Seitz-Schenk. Kolczyk and Oechsle (2) have already given a detailed description of this particle counting system. The objective of the investigations was to test the particle counting device under industrial conditions and prepare a particle balance in the filtration section of the brewery.
The portable instrument was connected to each of the sampling taps of the individual stations of the filter line. During filtration, measured values were recorded at the individual stations of the filter line every two minutes.

In this article, a measuring method for on-line measurement which has been newly developed for beer filtration will be presented. Up to now this kind of measuring systems was mostly suitable only for laboratory use.

Among the numerous applications of cross-flow microfiltration (CFMF) in the food processing industry, beer micro-filtration represents a wide potential market and an interesting technological challenge. CFMF and its potential applications in brewing are presented here. The purpose of this paper is to show that rough beer CFMF is a technical alternative to the conventional dead-end filtration with filter aids (diatomaceous earth).

Following on the positive reaction to the 1996 Seminar, and in view of the many questions and problem areas arising since that time, E. Begerow GmbH & Co. company of Langenlonsheim/Germany organised another Filtration Seminar in 1998.

Though modern filtration techniques are used in beer filtration, the filter aids required are still prepared to a very large extent manually.

This contribution deals with structure, possible modifications and mode of action of silica sols used in unfiltered beer to improve filterability and raise colloidal stability. Test methods applicable to commercial situations are presented.

Kieselguhr filtration is state-of-the-art nowadays for prefiltration of beer. No other filtration method comes even close in terms of performance and economics. Commercially available systems are mature and proven. Nonetheless, users still have questions about optimal apparatus and processes suited to their specific plant conditions. Familiarity with design and process characteristics simplifies selection for a specific plant situation.

This paper contains a report on fine and sterile filtration immediately ahead of filling in three medium-sized German breweries.
Filtration
For many breweries, a yeast-free filtrate in the bright beer tank is a minimum requirement in terms of microbiology. In order to achieve this, final filtration is required in order to assuredly separate out particles and yeasts. The most frequently used equipment is sheet filtration. Despite a number of new developments in recent times, sheet filtration involves certain disadvantages. This paper describes the results of a long duration test with a new system for final filtration.
