ABSTRACT:
Method and apparatus are described for removing material from a sump. The sump has substantially parallel and elongated sidewalls and has a longitudinal axis. The sump is enclosed with ends and a bottom and is adapted for filling with a water-solid mixture to form a slurry. A suction pump is mounted above the sump and extends into the sump for removal of water and solid material. Apparatus is attached to the suction pump for moving the suction pump along the longitudinal axis of the sump. The actual rate at which the suction pump is trammed is determined by apparatus which measures the concentration of the slurry near the pump and transmits a signal to a control unit which operates the tramming control circuit to maintain the concentration at a predetermined ratio of material to water.
