Abstract:
A method for extracting liquid from a liquid containing slurry comprising the following steps:providing a first foraminous container (14) having an inlet (26) and an outlet (28) and mixing and pressing means (16) mounted within the container (14) for movement between the inlet (26) and the outlet (28);continuously feeding liquid containing slurry under pressure through the inlet (26) into the first foraminous container (14) upstream of the mixing and pressing means (16), the pressure being sufficient to cause an initial volume of liquid within the slurry upstream of the mixing and pressing means (16) to be extracted; andbatch processing the slurry after it has been fed into the first foraminous container (14) by mixing the slurry in the first foraminous container (14) by moving it through the mixing and pressing means (16) after the initial volume of liquid has been extracted, and by subsequently pressing the mixed slurry in the first foraminous container (14) downstream of the mixing and pressing means (16) to cause a further volume of the liquid from within the slurry to be extracted.
