“…The amount of water stored was estimated at 91% corresponding to a solids content of about 9%. This value is similar to that of the commercial PVA gel from Kuraray Company (Japanese), about 10% [23]. The apparent density of PUF was determined by the mass to volume ratio of the foam and had a value of 21 ± 0.21 g/L.…”

“…In the MBBR system, the biofilm carriers play an important role in determining the overall efficiency and performance of treating wastewater [19,22]. Biofilm carriers for MBBR can be classified by non-porous or porous carriers such as activated carbon particles [23], fireclay [24], natural materials [25], and materials supported on polymers including polyethylene cylinder [26], polypropylene [27], poly(vinyl chloride) [28], polyurethane foam [29], poly(vinyl alcohol) gel [30]. Among mentioned carriers, non-porous carriers such as polyethylene cylinders (Kalnes types) possess a low specific surface area (about 300-500 m 2 /m 3 ) and are prone to the detachment of biofilm given their smooth surface [31].…”

In this work, seafood wastewater was treated by using MBBR reactor over a novel carrier (PUF-PVA gel) derived from the combination of a porous (PUF) and hydrophilic surface (PVA gel). A freezing-thawing method was used for the preparation of the novel PUF-PVA gel which is reported for the first time. Experimental results indicated that PUF-PVA gel carrier which possesses an excellent textural structure (specific surface area of 3.4 m2/g, pore size in the range of 10 -40 μm and hydrophilic surface) accounts for faster water immersion and better microbial adhesion, resulting in the biofilm content attached at the start-up stage 2.4 times higher relative to conventional PUF carrier alone. The MBBR system can be operated stably at a hydraulic retention time (HRT) of 7 hours in which the organic loading rate ranged from 2.5 kg COD/m3.day to 5.1 kg COD/m3.day. When operated at the organic loading rate of 2.5 kg COD/m3.day, the maximum COD and the nitrogen removal efficiency of MBBR based on the PUF-PVA gel carrier were 92 ± 0.6% and 89 ± 3.4%, respectively, which is higher than that of the PUF carrier.

“…This is because organic carbon is an energy substrate for many microorganisms, and microorganisms can cause the degradation of carbon sources and nutrients when adequate oxygen is provided. As a result, increasing carbon sources cause microorganisms to grow faster and increase biofilm density (Kozak et al, 2021).…”

The moving bed biofilm reactor (MBBR) has proven to be an effective system for the treatment of municipal and industrial wastewater. The main operating mechanism of moving bed biofilm reactors (MBBR) is the growth of attached biomass in biofilm carriers in the bioreactor with mixing provided by diffusers in aerobic bioreactors or mechanical stirrers in anoxic/anaerobic bioreactors. Biofilm formation is a complex process affected by microbial composition and properties. In this study, biofilm formation performance on Kaldnes K1 was investigated in two moving bed biofilm reactors (AnMBBR1 and AnMBBR2) using textile wastewater. Both MBBRs with a 40% fill rate were operated with a 6-hour hydraulic retention time (HRT). AnMBBR1 was operated under anaerobic conditions while AnMBBR2 was operated at different aeration rates (0.001-0.004 m3 air/m3reactor). The highest biomass concentration was observed in AnMBBR2 with a reactor aeration ratio of 0.004 m3air/m3reactor, corresponding to 4062 mg/L. The results showed that limited aeration improved biofilm formation on biofilm carriers rather than anaerobic conditions.

“…The wastewater treatment plant evaluated in this study is an integrated biological system. In full-scale application, the integrated system of several treatment units is mainly applied (Tianzhi et al, 2021) to effectively achieve pollutant removal and meet the required quality standards (Kozak, Cirik, & Başak, 2021). Therefore, an analysis of pollutant removal performance was carried out to determine the ability of the WWTP system to degrade pollutants contained in wastewater.…”

The development of WWTP in business activities needs to pay attention to getting appropriate WWTP that is more valuable to support sustainable development. This study aims to evaluate two systems of integrated biological WWTP; anaerobic-wetland, and anaerobic-aerobic-wetland, including the effectiveness of pollutant removal, operational and maintenance, and estimation of carbon emissions. The performance of pollutant removal was evaluated by analyzing inlet and outlet samples of WWTP. An operational and maintenance evaluation was carried out by studying the WWTP operating system and maintenance procedures supported by a literature review. Carbon emission estimation was carried out using a formula referring to the IPCC Guidelines (2006). Organic matter removal of anaerobic-aerobic-wetland WWTP in the form of BOD₅ and COD are 92.12% and 91.72%, respectively, higher than anaerobic-wetland WWTP are 88.69% of BOD₅ and 77.62% of COD. Anaerobic-aerobic-wetland WWTP needs more maintenance and operation than anaerobic-wetland WWTP. The highest carbon emission of both WWTP is 41530.91 kgCO₂ eq/year of anaerobic-wetland WWTP from the organic matter removal process and 46485.15 kgCO₂ eq/year of anaerobic-aerobic-wetland WWTP. Electrical energy consumption emits in anaerobic-aerobic-wetland WWTP is 22338 kgCO₂ eq/year higher than anaerobic-wetland WWTP at 4299.70 kgCO₂ eq/year. Total carbon emissions of anaerobic-wetland WWTP is 47404.58 kgCO₂ eq/year and anaerobic-aerobic-wetland WWTP is 68900.23 kgCO₂ eq/year.
