“…The size of the carrier varies from lengths of 7-15 mm and diameters of 10-15 mm. The carrier filling fraction (percentage of reactor volume occupied with carriers in empty tank) is normally 60-70% [5]. The Kaldnes carriers have a specific gravity of 0.96 with a specific biofilm protected surface area of 500 m 2 per m 3 bulk volume of carriers.…”

“…The dissolved oxygen (Do) concentrations in the MBBR ranged from 0.2 to 5.00 mg o 2 /lit depending on the influent organic loading rates. The temperature and PH in the reactor varied from 28 to 31 c and 6.72 to 7.88, respectively [6] and the pressures varying between 0.1 and 0.5 bar [5].…”

The aim of this study was to evaluate the performance of pilots physical, biochemical and chemical, in series and together for waste water treatment plants, processing oil in the Persian Gulf's oil and gas. For this purpose a Skimmer tank, MBBR reactor, Nano reactor, UV tank was used. Incoming wastewater system effluent desalination unit. Hydraulic retention time for various different system is intended. If you reduce the retention time of 18 to 12 hours, removed COD from 91% to 76% reduced. It was also found that the total removal of carbon materials in part MBBR 78.2% and 21.8% of the biofilm floating microorganisms. The results indicate that the whole system, which consists of 4 pilot that each part of its eliminates COD in waste water, the ability to remove 91% of COD. Solution input load 1.766 Kg COD/m 2 was signed. Finally, after the passage of treated wastewater and filters in 4 stages, has a relatively uniform quality and desirable.

“…The MBBR shows all the advantages of a standard biofilm reactor while at the same time treatment high particle loads (2). MBBRs have a number of advantages over conventional activated sludge (AS) technology, including fewer complexes to operate compared with AS systems, small footprint and reactor volume requirements, higher plant capacity due to higher biomass concentration, high resistance to hydraulic and organic load shock, increase in solids retention time and high removal performance under extreme loading conditions in plant upgrading.…”

Background and purpose: The performance of full-scale moving bed biofilm reactor (MBBR) was evaluated as an alternative for upgrading of Kish Island Mirmohana wastewater treatment plant. In this study activated sludge process upgrade to MBBR process and different operating parameters were compared. Materials and Methods: Conclusion:Hence, MBBR process is a good alternative for upgrading wastewater plants especially when they have inadequacy space or need modification that will require a large investment.

“…Moving-Bed Biofilm Reactors (MBBR), composed of moving carriers, is regarded as one kind of effective biological method to treat refractory organic industrial wastewater [12], in which the microorganism attached on carriers, does not fall off easily, contacts and degrades with pollutants completely [13,14], it seems also effective to applied anoxic MBBR reactor to treat the synthetic leather wastewater as a kind of refractory organic industrial wastewater, and achieve effective denitrification simultaneously [15].…”

One sample of PU synthetic wastewater was analyzed, its Total Nitrogen (TN) was mainly composed of about 300 mg/L nitrate, and three pieces of anoxic Moving Bed Bio-film Reactors (MBBR) were applied to treat it, one MBBR was run with raw wastewater, the second and third were with synthetic wastewater, and the results were as followings: TN could be removed off completely under the condition of relative low C/N ratio; the C/N ratio of removed pollutants was liner correlation with C/N ratio of influent, but the C/N ratio of effluent was increase violently, the above results demonstrated that, the external carbon source, necessary to the heterotrophic bacteria, was consumed more rapidly than nitrate nitrogen in initial denitrifying stage, then the nitrogen was utilized much more rapidly at later stage, and the ratio of C/N denitrification behaved as a chamfer linear.
