DESCRIZIONE
The present invention is situated within the fields of chemical and environmental engineering, being related to equipment for massive dissolution of gases in liquids via the formation of thin liquid films and the exchange of gases with said films. The equipment also provides movement of liquids over great distances via the upward movement of bubbles therein. In one embodiment, the equipment comprises means for altering the direction of the flow of water, said aspect being particularly useful for the recovery of liquid bodies such as lakes and bays. In addition to providing a high rate of dissolution of gases in liquids, the equipment of the invention is very energy-efficient and has a very large volumetric capacity, thereby overcoming the limitations of the prior art and being useful for the preservation and/or recovery of liquid bodies, being able, in certain applications, to operate in an energy-autonomous manner. The invention can be used in various situations where energy-efficient dissolution of gases in liquids is desired. Examples include: the preservation and/or recovery of liquid bodies such as lakes, rivers, lagoons, bays, mangroves and beaches; processes for preserving and/or improving the productivity of aquaculture systems; wastewater treatment systems; and the fixation of gases such as CO2, inter alia.
