“…However, as the VFAs were no more produced (the total accumulation reduced), methanogens converted it into biogas more optimally, supported by the achieved ideal pH condition. Hindrance to methanogens activity because of VFAs accumulation and pH drop in high substrate loading was also reported by Zhang et al [26] and Cuff et al [27]. As for the F/M = 0.56, it was expected that the rate of methane production could be the fastest, as the number of biomass was about double the available organic substrate, but the data revealed a divergent pattern.…”

“…Expanded granular sludge bed (EGSB) was further developed to enhance substrate-biomass interaction within the treatment system by expanding the sludge bed and increasing hydraulic mixing compared to UASB (Niwa et al 2016;Cuff et al 2018). Although well-established UASB and/or EGSB configurations mostly meet the requirements necessary for anaerobic treatment, unfavourable conditions regarding the disintegration of granules led to the development of AnMBR by coupling membrane technology with anaerobic treatment.…”

The development of innovative technologies in wastewater treatment create the concept of biorefinery in wastewater treatment plants (WWTPs), placing anaerobic processes in the highlight. Starting from the conventional anaerobic treatment processes to "closing the loop" scheme, next generation WWTPs are ready to serve for water, energy and materials mining. While bioenergy is still dominating the resource recovery, recovery of value-added materials (i.e. struvite, biopolymers, cellulose) are receiving significant attention in recent years. So, what are the state-of-the-art approaches for energy-efficient resource recovery and re-use from municipal wastewater? This paper follows a critical review on the validated technologies in operational environment available and further suggests possible market routes for the recovered materials in WWTPs. Considering the development and verification of a novel technology together with the valorisation of the obtained products, biorefinery and resource recovery approaches were gathered in this review paper from a circular economy point of view. General currently-faced barriers were briefly addressed to pave the way to a create to-the-point establishments of resource recovery facilities in the future.

“…Mao et al, 2015 reported that the optimum pH range for an anaerobic single stage or batch process should be 6.8 -7.4[15]. Similar findings on the obstruction of methane production because of VFAs accumulation and low pH were reported byCuff et al, 2018 and Zhang et al, 2019 [16,17]. C/N = 20 and C/N = 30 had comparable patterns of pH transition, and the recovered pH was similar in the range of 6.6 -7.1, suggesting the methanogenesis could smoothly occur.…”

Considering its high organic contents, A biological process, in particular anaerobically decomposition is considered to be the most suitable treatment for industrial tempeh wastewater. Among the important parameters that determine the success level of the process, C/N ratio was mentioned to play a significant role. Thus, this study was carried out to investigate the effects of different C/N ratios (10; 20; 30 and 40) on the decomposition process to produce methane gas. The experiment was conducted using 1L batch reactors with sludge from active cow manure biogas digester as inoculum. Several parameters such as pH, COD, BOD, VFAs and methane gas were monitored during the process to understand the mechanism. The experimental results confirmed that the C/N ratio significantly affected the anaerobic decomposition of tempeh wastewater, giving the best achievement for C/N = 30, with organic removal as high as 89% (COD) and total methane produced as much as 1240 mL in 14 days of observation. The balanced composition between carbon and nitrogen is important for the anaerobic process, higher organic loading (C/N = 40) will potentially lead to VFAs accumulation, meanwhile higher nitrogen concentration (C/N = 10) will stimulate complex transition, mainly denitrification and free ammonia formation. Both conditions will block the methanogenesis stage, resulting in a nonoptimal decomposition process and minimum methane production.
