A system for separating solids from a fluid stream. The system includes a
first separator device mounted to a container. The container includes a
settling compartment and baffle plate module, with the initial settling
compartment receiving the fluid from the first separator device. The fluid
stream proceeds through the baffle plate module. The solids within the
fluid stream will descend to the bottom of the container. A spiral blade
is positioned at the bottom of the container, with the spiral blade
adapted to convey solids to a first pump member. The speed of rotation of
the spiral blade may be varied. The first pump member discharges the
slurry to a second separator device. The second separator device will
discharge the separated fluid stream into the baffle plate module. In one
embodiment, the first separator device is a linear shaker and the second
separator device is a cyclone separator and linear shaker mounted in
tandem. The fluid exiting the baffle plate module may be directed into a
mixing compartment, with the mixing compartment being part of the
container. A method of separating solids from a fluid stream is also
disclosed.
