Plant for treating a liquid flux in one phase contactor and recirculation de-gassing device

摘要

The field of the invention is that of the treatment of liquids. More precisely, the invention relates to bringing liquids, and especially drinking water or aqueous effluents into contact with a treatment gas. A particular example of application of the invention is the ozonisation of liquids. The invention relates to a plant for the treatment of flows of liquids (12) of the type consisting in bringing the said liquids (12) into contact with a treatment gas (11) for a predetermined time of treatment, comprising: - means (20) for adding the treatment gas (11) to the flow of liquids (12) to form a homogeneous two-phase treatment mixture (13); -means (30) for forced dissolving of the said treatment gas (11) in the flow of liquids (12) to be treated interacting with means for degassing the said two-phase treatment mixture (13), so as to produce a single-phase treatment mixture (15); - and contacting means (40) ensuring a plug flow of the single-phase degassed treatment mixture (15) during the said predetermined time of treatment.
