Abstract (en)
[origin: EP1046718A1] Purification method for raw juice obtained by diffusion from sugar beets, comprising the stages of pre-defecation and defecation with CaO, first carbonation, filtration, second carbonation and additional filtration; before said pre-defecation stage a great fraction of raw juice obtained by diffusion is taken out, subjected to a pre-filtration stage and subsequently to a stage of membrane filtration, the obtained permeate being mixed to the clear juice of first carbonation and said mixture being prepared for the second carbonation. <IMAGE>
[origin: EP1046718A1] 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.
