Abstract

1,261,913. Settling suspensions. ENGLISH CLAYS LOVERING POCHIN & CO. Ltd. 21 Mareh, 1969 [21 March, 1968], No. 13832/68. Heading C1C. In a mineral effluent treatment in which the solids concentration is too low for floc formation, the solids concentration is automatically maintained at a suitable level by the addition of solids, e.g. returned sludge.
