Abstract
Starch conversion liquors having a pH value less than 7 and contaminated by a substance which can be removed by causing it to flocculate are clarified by increasing the pH value of the liquor whilst maintaining it at at least 80 DEG C by the addition of an alkaline substance, viz. one or more of the following, carbonates, sesquicarbonates, bicarbonates and hydroxides of the alkali metals and alkaline phosphates, silicates and aluminates, to a value at which flocculation occurs, adding finely divided bentonite and then removing the flocculating or precipitating matter from the liquor The fine colloidal materials are added in the form of hydro-sols or hydro-gels but the coarser materials may be added direct to the liquor. Bleaching agents more particularly alkaline and alkaline earth salts of chlorous acid, hypochlorous acid and sulphurous acid may be added initially if the liquor contains non-colloidal soluble colouring matter. After removal of the flocculating material the liquor may be treated with activated carbon.
