Abstract: A system for processing returned drilling fluid including a flow line configured to provide a return flow of drilling fluids and at least one vibratory separator having at least one screen, wherein the vibratory separator is fluidly connected to the flow low and is configured to receive at least a partial flow of fluids and separate the flow of fluids into a primarily fluid phase and a primarily solids phase. The system further includes a dual-trough configured to receive the primarily solid phase from the at least one vibratory separator and a slurry tank configured to receive the solids phase from the trough. Additionally, a method of processing a return drilling fluid including dividing the return drilling fluid into a primarily fluids phase and a primarily solids phase with a primary separatory operation. Furthermore, directing the primarily solids phase to a dual-trough having a first trough configured to receive a relatively large solids phase, and a second trough configured to receive a relatively fine solids phase. The method also including transmitting the relatively fine solids phase to a slurry tanks and processing the relatively fine solids phase in a secondary separatory operation.
