(EP874784-A1)      Stationary container (10) for keeping solids in suspension in a liq. by causing forced circulation, has an upper part of the container wall (11) shaped to guide the liq. flow along a downwardly curved path.    Also claimed are:(a) a method of keeping solids in suspension in a liq. which comprises either making the suspension flow in a circulatory path about a non- vertical axis, following a downward curve along part of the path, or flowing the solids and liq. together along a circulatory path about a non-vertical axis, so that the suspension remains homogeneous;(b) a container for mixts. of liqs. and solids, having either a partition from the bottom to the mid region and a smoothly, continuously curved upper wall to divert an upward flow outwardly and downwardly in a smooth circulatory movement, or a curved lower surface with an intermediate cusp, and(c) a method of making a slurry container which comprises folding opposite edges of a rectangular sheet about parallel fold lines, bending the sheet opposite to the folding to form a continuously curved container wall and fitting end walls to close the container.    USE -   The device can be used for fermenting slurries, e.g. from animal manure.    ADVANTAGE -   Solids are kept in suspension with lower energy input and cost than current methods. Suspension effectiveness is maintained for a wide range of solids, mfr. is simpler and cheaper, running is economical and performance is reliable over long periods.
