摘要

Beer is the fifth most widely consumed beverage in the world behind tea, carbonates (sodas), milk, and coffee, and it continues to be a popular drink with an average consumption of 23 L/person per year. The consumption of nonalcoholic beers is significantly increasing due to its fewer calories, the health consideration (against alcohol disadvantages), and prohibitions in some cultures and religions. This has led to the development of a healthy market and most major brewers have included alcohol-free beer in their product portfolios [1-3]. Brewers are very concerned that the techniques they use are the best in terms of product quality, cost-effectiveness, and environmental impact. Consequently, energy consumption, water use, and wastewater generation constitute real economic opportunities for improvements in the existing process. Beer clarification is probably one of the most important operations, when rough beer is filtered in order to eliminate yeast and colloidal particles responsible for haze. In addition, this operation should also ensure the biological stability of the beer. It should comply with the haze specification of a lager beer in order to produce a clear bright beer. Standard filtration consists of the retention of solid particles (yeast cells, macrocolloids, suspended matter) during dead-end filtration with filter aids. The variety of compounds (chemical diversity, large size range) to be retained makes this operation one of the most difficult to control [3,4]. Recently, membrane technology has been successfully used in clarification operation wherein kieselguhr filtration is replaced by cross-flow microfiltration (MF). Since cross-flow MF has been introduced, it was found that there could be additional benefits in quality, environments, health, safety, simplicity, flexibility, and cost. At the time being, several industrial membrane filtration plants are being operated in the big companies for producing famous brands [5-8].
