Abstract
A system for separating solids from fluid including a solid-laden fluid including a base fluid, a first separator configured to receive the solid-laden fluid and separate the fluid into a solids portion and an effluent, and a membrane separator configured to receive the effluent and separate the effluent into a permeate and a concentrate is disclosed. A method for separating solids from fluid including obtaining a solid-laden fluid, wherein the solid-laden fluid comprises a base fluid, feeding the solid-laden fluid through a centrifuge, removing at least a portion of high gravity solids from the solid-laden fluids, flowing the solid-laden fluid through a membrane separator, removing at least a portion of low gravity solids from the solid-laden fluid, and collecting a permeate from the membrane separator is also disclosed.
