Abstract: A mixing assembly includes a mixing basin, first and second pluralities of mixing paddles, and at least one motor. The mixing basin includes first and second parallel shafts extending therethrough. Each of the first and second pluralities of mixing paddles are positioned in an interior of the mixing basin. Each paddle of the first plurality of mixing paddles is coupled with the first shaft and configured to rotate about a first axis and each paddle of the second plurality of mixing paddles is coupled with the second shaft and configured to counter-rotate about a second axis. The counter-rotating mixing paddles are spaced apart to define a shear gap therebetween, and the motor is operable to drive the counter-rotation of the mixing paddles.

Abstract: A method for removing mineral scale from tubing is disclosed. The method may include the steps of making a first longitudinal cut along a length of the tubing, making a second longitudinal cut along a length of tubing, and removing a plurality of sections of tubing, wherein the sections of tubing are defined by the first and second longitudinal cuts.
