A static mixing apparatus for mixing a fluid, preferably a liquid is provided. The mixer comprises a plurality of chambers (5, 8, 12, 15) in series, the first chamber (5) of the series comprising a fluid inlet (4), and the final chamber (15) of the series comprising a fluid outlet (16), each chamber other than the final chamber in the series being in fluid connection with a subsequent chamber, the fluid connection comprising a plurality of orifices (7, 10, 11, 14) dispersed along a direction of flow, the nearest point to the fluid inlet of each subsequent orifice to the inlet overlapping with the furthest point from the fluid inlet of the previous orifice, and being off-set along the direction of flow from the previous orifice.

An adapter couples to a container and includes an adapter body and a mixing element. The adapter body includes a neck section and a cap section. The neck section has a first interior surface that defines a first channel extending therethrough. The cap section is coupled to the neck section. The cap section has a second interior surface that defines a second channel extending therethrough that is in fluid communication with the first channel. The mixing element is coupled to the first interior surface and extends into the first channel.

A device and a method for dispersing at least one substance in a fluid is disclosed. The device includes a process housing with a rotor, a fluid supply, a feed line for the at least one substance to be dispersed having at least one outlet opening, as well as a product outlet. The rotor brings about an axial delivery of a supplied fluid at least in some sections. Furthermore, the rotor brings about a radial delivery of the supplied fluid at least in some sections.

A system for removing a gas from a liquid comprises an aeration tank for aerating a raw liquid containing a gas to remove the gas by causing an agitated air flow through the liquid. A plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank, the aeriation plates perforated by a plurality of openings. Aerating the liquid occurs with the liquid flowing downward into the aeration tank, and an airflow flowing upward through the liquid from a point proximate to the bottom of the aeriation tank, wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air.
