“…They are used in many aerated systems, water treatment stations as well as municipal and industrial sewage treatment plants. Numerous studies have confirmed the high efficiency and reliability of treatment processes using such profiles [12][13][14]. The main characteristics required for reactor packing materials include large surface area (in m 2 /m 3 ), hydrophobicity, and density of the material used to produce the carrier (to ensure good circulation of the bed) close to the density of the liquid, in which it is found.…”

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.
