1. A blender system for use in a hydraulic fracturing system, the blender system comprising:
a mixing tub comprising an interior volume;
a movable divider associated with the mixing tub, wherein the divider is movable between:
an open position, in which the mixing tub allows liquid flow between a first portion of the interior volume and a second, distinct portion of the interior volume; and
a closed position, in which the divider prevents liquid flow between the first and second portions of the interior volume;
a divider control system that moves the divider between the open and closed positions;
a first input pump that pumps fluid into the first portion of the interior volume of the mixing tub;
a first output pump that pumps fluid dispensed from the first portion of the interior volume of the mixing tub;
a second input pump that pumps fluid into the second portion of the interior volume of the mixing tub; and
a second output pump that pumps fluid dispensed from the second portion of the interior volume of mixing tub.
