Abstract: A mixing apparatus and method of mixing additives are described herein. The mixing apparatus comprises a mixing conduit having a wall, a first end, and a second end opposite the first end. A fluid inlet is formed in the wall between the first end and the second end. A fluid outlet is also formed in the wall between the first end and the second end. An injection conduit fluidly connects the fluid inlet with the fluid outlet. A pump is disposed to pump fluid in the injection conduit. An additive conduit is fluidly coupled to the injection conduit.
