Abstract
Powder filtration has been part of the brewing industry for decades now and has proven to be a robust, effective, and low-cost process. It will continue to be part of the industry because powder filtration is not solely limited to the use of kieselguhr as a filter aid. 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 under research or are close to market release. In powder filtration, the brewing industry has relied upon a proven, effective, and flexible system, with high flux rate producing high-quality results.

Keywords: cost comparison, kieselguhr, powder filtration, TFS, Twin Flow System

 

S�ntesis
La filtraci�n con polvo ha estado presente en la industria cervecera desde hace m�s de medio siglo, y ha demostrado ser un proceso robusto, eficaz y de bajo costo. Seguir� siendo parte de la industria porque no est� limitado al uso de tierra diatom�cea (kieselgur) como adyuvante de la filtraci�n. El dise�o muy particular de la filtraci�n con polvo, y especialmente para el filtro con el Twin Flow System (TFS; sistema de flujo doble) permite el uso de muchos tipos de adyuvante, incluyendo algunos escogidos para sustituir el kieselgur y que est�n siendo estudiados o est�n pr�ximos a ser llevados al mercado. La filtraci�n con polvo le ha dado a la industria cervecera un sistema efectivo y flexible con altos caudales de filtraci�n.
