Abstract
In some embodiments, a pre-treatment source generates pre-treated oilfield fluid from oilfield fluid, prior to injection into an inverting filter centrifuge system. The pre-treatment source increases an efficiency of separating solids from the injected oilfield fluid. An inverting filter centrifuge coupled to the pre-treatment source generates filtered oilfield fluid from the pre-treated oilfield fluid. Post-treatment may be applied to the filtered oilfield fluid. Additional apparatus, systems, and methods are disclosed.
