Abstract (en)
[origin: DE19729802A1] The invention provides for a method and device for separating solid mineral grain materials, such as sand, from organic materials, suspended mateterials, easily or hardly soluble materials contained in a liquid-solid mix, for instance a mix from waste water purification plants. According to said method, the liquid-solid mix is tangentially introduced into a vessel (1), at an inlet port (13). Said liquid-solid mix flows towards an outlet port (16), in said vessel (1), at a sufficiently low rate so that when flowing said heavy components from liquid-solid mix, that is essentially solid mineral grain materials, settle forming a sediment bed (22). Said components forming sediment bed are removed and optionally dehydrated. The method according to the invention is characterized in that said liquid-solid mix is forcibly conveyed, in order to flow in a spiral fashion, between the inlet port (13) and the outlet port (16), at least through a partial deep area.
