Abstract: A columnar submersible pump system for use in a pump station having a wet well, the pump system including a vertical discharge control column with a support structure that is connected to the bottom of the wet well of the pump station to support the vertical discharge control column in the wet well, a submersible pump operably connected to the bottom of the vertical discharge control column in which the discharge control column has an internal conduit, wherein the submersible pump has an intake locatable above the bottom of the wet well, and the internal conduit has a flow control valve and a flow meter located in the internal conduit in the vertical discharge control column, wherein flow of liquid in the vertical discharge control column is controlled and measured.

Abstract: The present invention is a screening/washing/dewatering system which utilizes a solids handling pump to vacuum solids captured from a contaminated fluid stream from the system's screening mechanism and to convey them, in a concentrated form and through a closed conduit, to the washing/dewatering mechanism. The use of a solids handling pump enables a screening, washing and dewatering system to contain the captured solids in a completely closed system from their point of capture, through a conveyance system of unlimited length and configuration, to the point that the washed, dewatered screenings are finally discharged. Secondarily, the present invention offers the advantages of being able to capture as small of a solids particle size as is desirable and of providing effective washing and dewatering of the captured particles while minimizing the number of moving parts and maximizing the overall system reliability.
