Opis:
Barbotage reactors such as airlift reactors (ALR) and bubble column reactors (BCR) due to their two-phase flow are the subject of many studies. Their basic version is used for lifting, mixing, and aeration of liquids, while their hybrid version, supplemented with additional elements, can serve as a rector for transport, lifting, and aeration of liquids. The subject of the research were two design variants of a hybrid barbotage reactor differing in the position of the nozzle for circulation and aeration, both filled with a moving bed. Based on the previously obtained measurement results, a simple mathematical equation was proposed to describe the impact of the type of construction and filling the hybrid reactor with a moving bed on the oxygen concentration and mixing conditions as well as on the transport of liquids. It was found that the greatest impact on the transport of liquid in the hybrid barbotage reactor (HBR) had the location of the H-nozzle, and filling the reactor with a moving bed had the greatest impact on the oxygen conditions and mixing of the liquid in the case of the HBR reactor.

Opis:
Barbotage reactors extensively used in various branches of industry and bioengineering have been investigated in numerous studies. Recently the moving bed has become a popular solution in sewage and water treatment processes. Purification and transportation of small amounts of sewage from households and industrial plants is a hydraulic and technological problem for the sewage system and sewage treatment plants. A hybrid barbotage reactor (HBR) may be applied to transport small wastewater volumes while simultaneously aerating sewage. This study was conducted on a prototype hybrid barbotage reactor equipped with a pipe element for sewage circulation and aeration, which was packed with a moving bed to 20% of its volume. Based on the results of measurements, oxidation curves have been plotted and the efficiencies of sewage treatment have been calculated for the reactor aerated in the continuous and intermittent modes. The amount of energy used to treat and transport sewage has been established.
