ABSTRACT:
This invention relates to settlement tank installation for the clarification of liquids particularly water and including an inclined plate assembly for solids removal. The plate assembly comprises a multiplicity of flexible sheets suspended from an upper end and weighted at their lower ends which are located to give the desired angle of inclination to the sheets wherein preferably the upper ends of the sheets are connected to a fixed frame and the lower ends to a movable frame through rods extending across the frame and attached to the sheets. The assembly is installed in a tank with an inlet for liquid to be treated opening into a separating chamber, having perforated side walls next to which the inclined sheets are located and opening into an outer collection channel with the perforations extending substantially two thirds of the height of the inclined sheets and wherein an outlet for treated liquid is provided arranged to control the level of the liquid at the height of the top of the sheets in the end of the collection channel remote from the inlet. The tank also preferably including collection troughs in the floor at each end and a floor cleaning sweeper assembly comprising a blade extending across the width of the floor and connection at each side centrally to a rope passing around pulleys located at the top and bottom of each end of the separating chamber.
