DISPOSITIVO PARA EL TRATAMIENTO DE LIQUIDOS POR GASIFICACION.

摘要

A device for the gasification of liquids comprises a hollow annular member (10) bounding a central liquid flow passageway (11). The member has a gas inlet (12) into the hollow and apertures (14) surround the passageway so that gas introduced from the hollow into liquid flowing in use up through the passageway forms gas bubbles in the liquid. A flow diverter hood (20) extends above the passageway to impart a horizontal component of velocity to the gasified liquid flow. The devices are used in fish farm plants in a closed circuit liquid flow channel to simulate river conditions. The devices are also used in oxidation ditch sewage treatment plants simultaneously to aerate the waste water and to drive the circulation flow.
