Abstract

Purification of sugar beet juice which can exploit the traditional process, without increasing the use of lime, without increasing the environmental effects due to sludge, with reduced carbon dioxide emissions : A purification method for the raw juice obtained by diffusion from sugar beets, comprises sequential stages of pre-defecation and defecation with calcium oxide, carbonation, filtration, a second carbonation, and additional filtration. Before pre-defecation, a great fraction of the raw juice obtained is taken out, pre-filtered, then passed to a membrane filtration stage. The permeate obtained is mixed to the clear juice of the first carbonation, and the mixture routed to the second filtration.
