Fluid Conditioning and/or Treatment System

A fluid conditioning and/or treatment system is disclosed. A bell housing with a pressure relief element, for example a rupture disk, has an external shoulder to seat within a tubular. One or more filter chambers, with slots in the walls thereof, are releasably connected to the bell housing. A magnet mandrel is attached to the lowermost filter chamber. Fluids, for example drilling/completion fluids, are pumped downhole through the apparatus, and the filter chamber(s) and magnet remove solids and ferrous materials from the fluid stream. Threaded connections and connectors create a modular system, with the various elements easily changed out.
