A mixer and method for mixing are provided. The mixer includes a housing including a fluid inlet, an additive inlet, and an outlet. The housing defines a mixing chamber in fluid communication with the fluid inlet, the additive inlet, and the outlet. The mixer also includes an impeller disposed in the mixing chamber. When rotated, the impeller pumps fluid through the fluid inlet. The mixer also includes a slinger disposed in the mixing chamber and configured to receive the fluid from the impeller and to receive an additive from the additive inlet. When rotated, the slinger slings the fluid and the additive radially outwards. The mixer further includes a flush line extending between the mixing chamber and the additive inlet. The flush line is receives, from the mixing chamber, a portion of the fluid pumped by the impeller and to deliver the portion of the fluid to the additive inlet.

The mixer also includes an impeller disposed in the mixing chamber, wherein, when rotated, the impeller draws fluid through the fluid inlet. The mixer also includes a slinger disposed in the mixing chamber and configured to receive the fluid from the impeller and to receive an additive from the additive inlet. When rotated, the slinger slings the fluid and the additive radially outwards. The mixer further includes a stator disposed at least partially around the slinger, with the stator including vanes spaced circumferentially apart so as to define flowpaths therebetween.
