ABSTRACT:
Impure aqueous media, e.g., contaminated white wines or sugar-containing liquors, are purified by (i) immersing therein a package which comprises a unit purifying amount of a characteristically chemical active charcoal powder enveloped within a film of a water-soluble, notably PVA polymer, (ii) permitting such package to dissolve and intimately contacting the active charcoal powder with the impure aqueous medium for such period of time as to sorb the impurities therein onto the active charcoal powder, and (iii) thence recovering and optionally filtering the aqueous medium thus purified, and whereby essentially none of the water-soluble polymer is present therein.
