“…Another studies show similar result for efficiency of COD removal by ABR method in piggery 6 wastewater, 60% (Ye et al, 2014). The result that is conducted by Chen et al, (2016) showed efficiency of COD removal by 40% (at 13-22 days), and it is similar with the average efficiency in this study. The C/N ratio in the study showed a value of 0.56 ± 0.09, with the contributing bacteria were 92.70% for anammox and 7.30% for denitrification.…”

Aim:The purpose of this study was to determine the efficiency and characteristics of pig wastewater treatment. This was to be achieved using ABR with the addition of effective microorganism4 (EM4) as a bio-activator during the startup process (R1) and without EM4 (R2). Methodology and Results: Piggery wastewater is poured into ABR with 12 hours HRT (hydraulic retention time), though it is reduced to 6 hours after the concentration is stable. The COD removal efficiency at 12 hours HRT was 60% (R1) and 51% (R2). However, the results did not change significantly, since the 6 hours HRT COD efficiency was 57.8% (R1) and 51.3% (R2). The biomass growth rate at R1 is faster than R2 with Food to Microorganism Ratio (F/M) 0.4-0.89 (R1) and 0.68-1.38 (R2) while the yield of methane gas formation was 0.25-0.28 L-CH4/g-COD. Conclusion, significance, and impact study: COD effluent is the total organic material present in the piggery wastewater effluent, which is discharged into water bodies without meeting the set quality standards. This damages the quality of water bodies. The wastewater treatment needs to be prioritized to meet quality standards of COD effluent. Also, the addition of EM4 to the activated sludge reactor improves the COD removal efficiency and biomass growth, though advanced treatment is still needed for piggery wastewater.

“…Despite its advantages, few studies were performed to examine the application of the process as posttreatment of e uents with low ammonium ion concentration and higher COD/N ratio, which are characteristic conditions of the anaerobic treated sewage in tropical countries WWTP (Sanchez -Guillén et al, 2014;Leal et al, 2016;Chen et al, 2016;Li et al, 2019 andWang et al, 2020). COD/N ratio plays an important role when choosing and operating technologies and process for nitrogen removal in a WWTP.…”

This study aimed to verify if subtropical annual seasonality variation of organic matter and nitrogen ratio facilitates the use of anammox process as a post – treatment of anaerobic effluent. We characterized the anaerobic effluent from a wastewater treatment plant (WWTP) located in Campinas/SP, Brazil. The collected composed samples were from an UASB reactor in different days, hours and months during one year. We concluded subtropical annual seasonality of COD/N ratio range (2.2 to 3.1) from anaerobic effluent indicates that the use of anammox process is appropriate as post-treatment of anaerobic effluent in subtropical areas. However, as Total COD degrades over time and as total nitrogen concentration is influenced by seasons, these factors need to be taken into account in the project and operation of the reactor over the year.
