ABSTRACT:
A highly versatile fluids and particulate separator that can be used in a centrifugal mode or centrifugal with gas flotation mode without the use of rotating apparatus within the cell. A pump and recirculation system provide the means for centrifugal force and gas flotation. A buoyant self adjusting discharge assembly with a vortex of fluids surrounding it provide the exit path for separated light fluids and light particles. In oil and water separation the buoyant assembly allows self discharge of the oil and can be used with high oil to water ratios at high volume. Oil spill cleanup is possible. Conversely gas flotation may be used for low volume separating applications.
