“…winery and beer wastewater (Moreira et al 2015;Yague et al 2000), pulp and paper mill effluents (Vepsalainen et al 2011), olive mill wastewaters (Aissam et al 2005), landfill leachates (Bardi et al 2017b) and mainly tannery wastewaters (He et al 2007). The core of wastewater treatment plants (WWTPs) consists of engineered biological ecosystems (activated sludge) based on bacteria that allow an economical and sustainable treatment of wastewaters (Leyva-Diaz et al 2017). However, bacteria are ineffective in the removal of compounds characterized by high toxicity and recalcitrance, such as tannins (Lofrano et al 2013;He et al 2007).…”

Tannins are secondary metabolites widely distributed in the plant kingdom. They act as growth inhibitors towards many microorganisms: upon microbial attack, they are released helping to fight the infection of plant tissues. Extraction of tannins from plants is an active industrial sector with several applications from the beginning of the industrial era. Actually, tannins have many industrial applications in oenology, animal feeding, mining and chemical industry and, in particular, in the tanning industry. But tannins are also considered very recalcitrant pollutants in wastewaters of different origins. The ability to grow on plant substrates rich in tannins and on industrial tannin preparations is traditionally considered peculiar of some species of fungi that have developed mechanisms to tolerate the toxicity of tannins producing a complex enzymatic pattern active in the transformation of these substrates, mainly by hydrolysis and oxidation. Filamentous fungi capable of degrading tannins could have a strong environmental impact as bioremediation agents mostly in the treatment of tanning wastewaters.

“…Therefore, a new type of IFAS-MBR was designed, which can reduce the concentration of suspended activated sludge mixture and thus reduce the quorum sensing strength. Most of the studies that compare the pure MBBR-MBR and the IFAS-MBR go in the favour of IFAS-MBR [25] and most of the studies that compare the traditional MBR and the IFAS-MBR also go in the favour of IFAS-MBR [26]. The benefit of IFAS is that nitrification can be obtained at less than half of the SRT than what is required in CAS plants [27].…”

With the improvement of water treatment technology, the biological nitrogen removal of sewage has also made a great progress. Research economic and efficient denitrification technology has become the hot issues of domestic and foreign scholars. During the long-term operation of wastewater treatment, the differences in physiological and biochemical characteristics of traditional denitrification technologies make various functional microflora interact with each other in the same system, which restricts the efficiency and stability of the process. Therefore, some new treatment technologies emerge. This review introduces the new technology and its development direction of biological nitrogen removal in recent years from two aspects: New technology of the original technology improvement and combination and new technology based on the principle of development, engineering examples in the wastewater treatment industry are enumerated.

“…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.
