In one aspect, a mixing arrangement is provided for a tank mixing system which includes a tank defined by a side wall, a bottom and a top, the top including at least one opening therethrough. The arrangement includes a non-rotating elongated arm extending through the opening in the top of the tank, the arm pivoted for movement about a pivot axis; an impeller positioned on the arm for movement therewith and within the tank, the impeller moving back and forth along an arcuate path within the tank as the arm pivots back and forth about the pivot axis. In another aspect, a ball-and-socket assembly is positioned above the top of the tank and is movable along a curved path to mope an impeller in a curved path within the tank.

Mixing arrangement for tanks

A radial impeller includes a cover having a frusto-conical portion and multiple blades extending radially outwardly. Related mixing systems involve positioning the radial impeller with blades adjacent a flow opening of a tank to draw water through the flow opening when the impeller is rotated.

In-tank mixing system and associated radial impeller

A static mixer element and a method for mixing first and second (or more) fluids using a static mixer element. The static mixer element includes a directional flow axis which points in an intended downstream direction opposite to an intended upstream direction. The static mixer element also includes interdigitated static mixer blades. The blades each have a concave side which faces generally in the intended upstream direction at an acute angle with respect to the intended upstream direction. The static mixer element is placed in a pipe with the directional flow axis of the static mixer element pointing downstream. The first and second fluids are introduced into the pipe upstream from the static mixer element. Optionally, other static mixer elements can be added downstream, wherein even-numbered elements are rotated ninety-degrees about the directional flow axis from odd-numbered static mixer elements.

Static mixer element and method for mixing two fluids

A baffle for insertion into a container. The baffle includes a concave surface defined by two essentially parallel line segments connected to each other at their ends by line segments subtending an angle. The baffle further includes structure for mounting to a container so that the line segments are essentially parallel to and offset from a side wall of the container. Preferably, structure for mounting is structure for suspending the baffle from a first end wall of said container without attachment to a container side wall. The concave surface is preferably a curvilinear concave surface and the contiguous line segments subtending an angle are in the form of an arc. The baffle is preferably glass coated and sized to pass through an opening in an end wall of the container.
