1. An apparatus comprising:
- a housing configured to be sealed in a liquid-tight manner;
a plurality of grading screens configured to reside within the housing, the plurality comprising at least;
a first grading screen, an interior region of which defines a first compartment; and
a second grading screen arranged concentrically with the first grading screen, wherein a region between the second grading screen and the first grading screen defines a second compartment;
wherein a region between the housing and the plurality of grading screens defines a third compartment; and
first and second end plates configured to engage first and second ends, respectively, of the plurality of grading screens in a liquid-tight manner such that fluid communication between adjacent compartments is restricted to occurring through the grading screen there between.
