“…At the genus level, the dominant microorganisms in MDC‐E were Trichococcus (23.66%), Marinobacterium (19.48%), Mangrovibacterium (12.48%), Acetobacterium (5.88%), and Rhodococcus (4.48%), which were obviously different from those in MDC‐C. Trichococcus belongs to the microbial populations of Firmicutes , and had been certified to be associated with denitrification and degrading complex organic compound in the process of COD removal 46 . The relative abundance of Marinobacterium and Mangrovibacterium in MDC‐E ranged from 1.36% to 19.48% and from 0.67% to 12.48%, respectively.…”

BACKGROUND: Due to the rapid development of shale gas extraction, the treatment of flowback water (FW) is becoming one major challenge because of its high saline, high ammonium (NH 4 +), high phosphorus (PO 4 3−), and complex organic contents. This study aimed to treat the high-salinity synthetic FW and recover nutrient using the air-cathode (PMo/CB) microbial desalination cells (MDCs). RESULTS: The removal efficiency of chemical oxygen demand (COD) exceeded 90% along with an electricity generation of 105.6 mW m −2. The highest removal and the recovery efficiency of 300 mg L −1 NH 4 + and 100 mg L −1 PO 4 3− were 65.6 ± 19.0% and 75.8 ± 32.0%, 52.6% and 57.8%, respectively. High-throughput sequencing analysis of anodic biofilms indicated that Firmicutes, Bacteroidetes, and Proteobacteria enriched at high influent NH 4 + concentration were responsible for producing electricity and degrading complex organics. Two denitrifying bacteria, Trichococcus and Marinobacterium, promoted the COD removal and also improved the electricity generation. Rhodococcus, a kind of heterotrophic nitrification-denitrification bacteria, contributed to nitrification in the cathodic chamber along with enhancing the denitrifying degradation of COD. Nitrincolaceae, capable of heterotrophic nitrate reduction to ammonium, were favorable to the recovery of NH 4 +. CONCLUSIONS: Overall results concluded that PMo/CB-MDC could be a promising alternative technique for the efficient treatment of FW and a pretreatment process for separating nutrient from the recovery chamber.

“…The time needed for biofilm formation and adaptation may vary depending on the technical and technological solutions. In a study conducted by Mielcarek et al [2016Mielcarek et al [ , 2017, the time needed to reach a stable biofilm in the SBBR type reactor working only under anaerobic conditions was ca. 43 days with waste beer used as an organic substrate and ca.…”

“…which ensured a stable volume of biomass in the reactor throughout the experiment. A solution of acetic acid was used as the substrate and its dose was adopted after an overview of literature data [Mielcarek et al 2016[Mielcarek et al , 2017Park et al 2008]. The initial concentration of total organic carbon (TOC) in wastewater was assumed at 140 mgC•dm -3 .…”

This study investigates the feasibility of using an organic substrate in the form of acetic acid to enable wastewater denitrification in a Sequencing Batch Biofilm Reactor (SBBR). The impact of nitrates presence on the yield of biological dephosphatation was determined as well. The experiment included 296 cycles and was divided into 4 series differing in the load of nitrates. The N:(C and P) ratios were: 7:(140 and 7); 35:(140 and 7); 70:(140 and 7) and 140:(140 and 7). The hydraulic retention time in the reactor was 12h (6h of mixing-dissolved oxygen concentration below 0.1 and 6h of aeration-concentration of dissolved oxygen 3.0±0.8 mgO 2 •dm-3). The study demonstrated that the 30-day adaptation period (60 cycles) was sufficient for the development of a stable biofilm. The C:N ratio of 2 ensured the total nitrogen concentration in the effluent below 1 mgN•dm-3. The mean efficiency of biological dephosphatation reached 7.0, 17.4, 18.7, and 30.3% in series 1-4, respectively. In the case of series 2 and 3, no significant differences were demonstrated in the total phosphorus concentration in the effluent. In the other series, the differences turned out to be significant.

“…They concluded that fermented butter wastewater could simultaneously improve the quality of phosphate and nitrate in effluent, which may be due to the introduction of fermentation wastewater to increase the content of easily available compounds and the advantage of acetic acid in VFAs that can be used for phosphorus removal and denitrification [49]. In another study, they also proved the feasibility of waste beer as a carbon source to enhance denitrification in an anaerobic sequencing batch biofilm reactor (AnSBBR) [50].…”

Biological nitrogen removal from wastewater is widely used all over the world on account of high efficiency and relatively low cost. However, nitrogen removal efficiency is not optimized when the organic matter has inadequate effect for the lack of a sufficient carbon source in influent. Although addition of an external carbon source (e.g., methanol and acetic acid) could solve the insufficient carbon source problem, it raises the operating cost of wastewater treatment plants (WWTPs). On the other hand, large amounts of sludge are produced during biological sewage treatment, which contain high concentrations of organic matter. This paper reviews the emerging technologies to obtain an internal organic carbon resource from sewage sludge and their application on improving nitrogen removal of low carbon/nitrogen wastewater of WWTPs. These are methods that could solve the insufficient carbon problem and excess sludge crisis simultaneously. The recovery of nitrogen and phosphorus from treated sludge before recycling as an internal carbon source should also be emphasized, and the energy and time consumed to treat sludge should be reduced in practical application.
