ABSTRACT:
The present invention concerns a process for secondary purification and stabilization of liquids containing polyphenols and/or proteins. The liquid to be treated is first subjected to a centrifuge, or similar apparatus, which performs the primary purification of the liquid. The treated liquid is then mixed with stabilizing means that adsorb the polyphenols and proteins and filter means that retain the fine turbidities contained within the liquid. The liquid mixture is then transferred to an alluvial filter apparatus in laminar flow wherein the filter means and stabilization means along with the adsorbed polyphenols and proteins form a filter cake. The purified liquid is then transported to subsequent treatment while the filter cake is subsequently treated with a solution which dissolves the polyphenols and protein thereby regenerating the stabilization means and the filter means.
