Abstract

Sedimentation vessel comprises a hollow vertical pref. cylindrical, body section fitted with a bottom, a top and an internal partition. Essentially, the bottom, top and partition are all made to identical shape and size, pref. of frusto-conical form, so that they can all come from one mould. Vessels covering a range of capacities can be made simply by altering the length of the body section, so that prodn. costs are held down.
