2021/4/13The microbial fuel cell (MFC) efficiency was assessed by using biochar electrode. Electrodes were made of silicon (Si0.4), zinc (Zn0.4), and copper (Cu0.4) in 40% proportions mixed with derived waste coconut shell (CS) biochar materials after the carbonization process. The specific surface area of CS-Si0.4 (0.1920 m2 g−1), CS-Zn0.4 (0.2025 m2 g−1), and CS-Cu0.4 (0.2532 m2 g−1) is

Enhancement of denitrification performance with reduction of nitrite accumulation and N2O emission by Shewanella oneidensis MR

Finally, the performance of denitrification enhanced by S. oneidensis MR-1 was testified by laboratory groundwater treatment experiment. This study suggested the potential role of S. oneidensis MR-1 in accelerating nitrate bio-transformation in nitrogen geochemical cycle and increasing bio-treatment of nitrate contamination with negligible harmful intermediates (nitrite and N2O) accumulation.

Recent advances on the application of UV‐LED technology

A recent study demonstrated that photoreactivation is the most important mechanism of reactivation that occurred during UV‐LED treatment of E. coli in water treatment. After processing with different dual combination of different wavelengths of UVA/UVC‐LEDs (310/275 nm) and UVC/UVC‐LEDs (267/275 nm) treatment, the photoreactivation was significantly repressed compared to those of 267

Phosphorus removal performance of microbial

2021/3/15The microbial community was analyzed to identify the microbial transformation mechanism. However, because the microbial-enhanced CWs in this study was operated at a laboratory scale, future research should focus on long-term and large-sale CW operations

Wastewater

Microbial corrosion of concrete in sewers is known to be caused by hydrogen sulfide, although the role of wastewater in regulating the corrosion processes is poorly understood. Flooding and splashing of wastewater in sewers periodically inoculates the concrete surface in sewer pipes. No study has systematically investigated the impacts of wastewater inoculation on the corrosion of concrete in

Study of sulfate

The end products of the SRAO reaction were tested, and the microbial community was analysed to explain the mechanism. Moreover, the N/S ratio was explored to describe the structure of the products. A determination and observation of the SRAO process was carried out for the comprehensive treatment of wastewaters containing high levels of ammonium and sulfate.
