Abstract:
1. A centrifuge for enhancing the separation of entrained solids within a solution comprising: a rotatable bowl for supporting a volume of fluid, the rotatable bowl operatively connected to an input port for introducing fluid to the rotatable bowl; a fluid discharge port for removing fluid from the rotatable bowl; a solids discharge port for removing solids from the rotatable bowl; and a gas injection system operatively connected to the rotatable bowl for introducing a gas into the solution prior to introduction of the solution to the rotatable bowl and dispersing the gas within the rotatable bowl and liquid, the gas injection system being operable to adjust the density and viscosity of the fluid to enhance the centrifugal separation of the entrained solids from the solution during rotation of the rotatable bowl, wherein the entry point of the solution into the rotatable bowl includes a nozzle operatively connected to a pump and to the gas injection system.
