Beer filtration is inherently a balancing act. Precoat filtration
technology is the most widespread method of filtration used. It
has been developed over the last decades into an increasingly
efficient filtration technology. We have to discuss the removal
of haze particles, haze-producing substances, and removal of
organisms. Filtration must be tight enough to remove these
unwanted components, without losing the essential quality of
the beer filtered. It is the unique design of powder filters, and
the twin flow system (TFS) filter in particular, that allows for
the use of many types of filter aids, including replacements for
kieselguhr, some of which are being researched or are close to
market release. In powder filtration, the brewing industry has
relied on a proven, effective, and flexible system, with a high
flux rate producing high-quality results.
Fred Scheer graduated in 1976 from Doemens Brewing
Academy (Munich, Germany) with a brewmaster’s degree in
brewing and malting. He worked at several breweries in Europe
before emigrating to the United States in 1983 to help establish
Capital Brewery in Madison, WI. Later, he was technical
director for the Frankenmuth Brewery, a 50,000 bbl brewery in
Michigan. He also worked for Pabst Brewing in Milwaukee, WI,
in corporate brewing and for their China operation. In 2011
Fred accepted the position of director of brewing and process
