a slurry dividing apparatus is configured to divide a main slurry stream into smaller constituent slurry streams , wherein each stream contains a desired proportion of suspended solids . the dividing apparatus includes a main flow channel and a plurality of branch flow channels extending upward from a flow divider that terminates an upper end of the main flow channel . the main slurry stream enters the main flow channel , at an inlet opening thereof , and is decelerated , by an upward extension and expanding cross - section of the main flow channel , before reaching the flow divider and being divided into the smaller constituent slurry streams flowing within the plurality of branch flow channels . each of the smaller streams flows up and then over a weir , which extends across an upper portion of each of the branch flow channels , and then down into a corresponding discharge flow channel of the apparatus .
