Abstract
There is disclosed a low energy separator of the type comprising a vessel (1) in which rotational movement of liquid in the vessel is sufficient to cause or enhance an inward sweeping effect towards an annular opening in the base (3) of the vessel on solids accumulated at the base of the vessel (1) while being of sufficiently low energy that separation of the solids components in the liquid in the vessel (1) is brought about primarily by gravity. In order to reduce turbulence caused by the outlet (7) in the upper region of the vessel (1), a flow modifying means (14) is provided which guides liquid circulating in the vessel (1) at an upper region thereof to a level at or below the lower level of the outlet (7).
