Abrégé

Systems and methods for diffusing gas into a liquid are disclosed. In some cases, the methods include tangentially introducing a liquid into a cylindrical chamber having a cylindrical inner wall such that the liquid develops a spiral flow. In some cases, gas bubbles are orthogonally introduced into the liquid as the liquid flows through the chamber. In some cases, a flow of the liquid and the gas bubbles is controlled such that a ratio of a liquid flow rate to a gas bubble flow rate does not exceed values which convert non-bacteria enriched, clear water into froth. In such cases, a mixture of the liquid and the gas bubbles to exit the chamber near an output end. While the liquid can include clear water, in some instances, the liquid also includes bacteria (e.g., surfactant-producing or non-surfactant-producing bacteria) and/or bacterial nutrients that allow for improved bioremediation.

• B01F 1/00 - Dissolution

Abrégé

The present invention relates to an apparatus and a process for dissolving gas in a liquid is provided. The process comprises: tangentially introducing a liquid into a cylindrical chamber having a cylindrical inner wall with sufficient volume and pressure to develop a vortex in the flowing liquid; introducing gas into the flowing liquid during at least a portion of its travel along vessel, the gas being introduced orthogonally to the stream through means located at the chamber inner wall for developing gas bubbles within the liquid. The apparatus comprises: a cylindrical chamber having a cylindrical inner wall, the chamber being oriented in any direction enclosed at both ends and with an entry port to introduce liquid to develop a spiral flow of liquid along the chamber inner wall toward the output end, a porous wall to permit the introduction of gas orthogonally into the stream to develop gas bubbles within the stream, and an exit port to discharge the mixture of gas bubbles and liquid.

• B01F 1/00 - Dissolution

Abrégé

The present invention relates to an apparatus and a process for efficient hydrophobic particles to gas bubble attachment in a slurry is provided. The process comprises: tangentially introducing a slurry stream into a cylindrical chamber having a cylindrical inner wall with sufficient volume and pressure to develop a vortex in the flowing slurry; introducing gas into the flowing slurry during at least a portion of its travel in the chamber, the gas being introduced orthogonally to the stream through means located at the chamber inner wall and for developing gas bubbles which move into the slurry. The apparatus comprises of: a cylindrical chamber having a cylindrical inner wall, the chamber being oriented in any direction, enclosed at both ends, and with an entry port to introduce the stream of slurry to develop a spiral flow of the stream along the chamber inner wall toward the output end, a porous wall to permit the introduction of gas orthogonally into the stream to develop gas bubbles within the stream, and an exit port to discharge the mixture of slurry and gas bubbles.
