Abstract
NORIT Process Technology and Heineken Technical Services,
in a joint research project, have succeeded in progressing cross-flow
microfiltration to the point in which it is becoming a technical and
economic alternative to kieselguhr (diatomaceous earth) filtration in
breweries. The team has solved the persistent problems of high
membrane-fouling rates, short run times, and inadequate cleaning
procedures. The key to this progression has been the development of a
new cleaning strategy as well as the excellent properties of the
cross-flow membranes themselves, which are discussed in this paper.
Keywords: beer filtration, cross-flow filtration, diatomaceous
earth, kieselguhr, membrane filtration
Síntesis
En un proyecto conjunto de NORIT Process Technology y
Heineken Technical Services, se ha logrado mejorar la microfiltración en
flujo transversal (“cross-flow”) a tal punto que se está convirtiendo
en una alternativa técnica y económica a la filtración de cerveza con
tierra diatomácea. Estos equipos han resuelto los problemas más
persistentes: alta frecuencia de “embarramiento” de las membranas,
corridas cortas y procedimientos de limpieza inadecuados. Este avance se
debe a las excelentes propiedades de las nuevas membranas de flujo
transversal y al desarrollo de una nueva estrategia de limpieza.
