Abstract

An improved method of decantation in a decanter for separating solid particles suspended in a liquid consists of creating a single thermal barrier located solely in the liquid phase least charged with product to be separated. In the case of a continuous decantation method the thermal barrier is formed between the inlet zone for the mixture to be decanted and the outflow zone for the decanted liquid.
