“…In one of the reports from this period, it was verified that biodigesters used in India took ≤55 days to digest cassava wastewater originating from the sago industry, leading to a costly process. 69 Therefore, researchers opted for studying three different treatment methods to increase treatment efficiency: random-packed anaerobic filter, UASB and hybrid reactor. The latter reached 93% COD removal and 85% solid removal in 24 h, proving to be the best solution.…”

The cassava processing chain is potentially sustainable and can actively contribute in the change towards the circular economy. The present article aimed at assessing global scientific research trends on anaerobic treatment of wastewater originating from cassava processing. In this regard, a bibliometric analysis of anaerobic digestion and biogas production of wastewater from cassava processing was carried out within the period between 1980 and 2020, using the Scopus database. The results showed that the interest of research on the subject grew exponentially from 2001, being mainly focused on the recovery of by‐products such as methane, biogas, hydrogen, bio‐oil, bioethanol, propionic acid and butyric acid. Full‐scale anaerobic wastewater treatment already is carried out in countries such as India, China and Thailand, and has been explored largely in developing countries. The studies demonstrated that wastewater bioconversion is an attractive solution, with widespread full‐scale applications. The authors of the present work expect that new publications on environmental and economic sustainability of the processing industry of cassava by‐products will contribute to the sector's development towards a green and low‐carbon economy. © 2021 Society of Chemical Industry (SCI).

“…The optimum treatment method for processing waste water from the tofu industry is an anaerobic process since the waste water from the tofu industry comprises a high organic load [5][6][7][8][9][10]. Complexes with a high content of organic materials are broken down into simpler compounds by the anaerobic process's degradation mechanism.…”

Wastewater from the food industry that contains a high organic load, such as wastewater from the tofu manufacturing process, requires an appropriate and efficient treatment system to reduce pollutants before being discharged into water bodies. The most suitable treatment for high organic loads is the anaerobic treatment system. The anaerobic treatment process is a system of suspended media, attached media, or the combination thereof as a hybrid. This study uses a Hybrid Upflow Anaerobic Sludge Blanket (HUASB) reactor with the consideration that this reactor has advantages in maintaining high concentrations of biomass, high operating load rates, good decomposition capabilities, and good solid-liquid separation due to suitable granulation. The purpose of this study was to determine the effect of the addition of the trace metal FeCl3 on biogas production and the ability to remove pollutants in the tofu industrial process wastewater treatment in the HUASB reactor. The operation of the reactor uses variations in the concentration of tofu industrial waste water (75 and 100%) and trace metal concentrations (0.3–0.6 mg/L). The optimum biogas production was obtained with 8190 mL at a concentration of 75% tofu industrial waste water, a trace metal concentration of 0.6 mg/L FeCl3, and removal of COD and TSS of 94.09% and 94.2%, respectively. The role of the trace metal FeCl3in the anaerobic process shows that it is a source of nutrition for increasing the growth of microorganisms in anaerobic systems so that biogas production and pollutant removal are increased.

“…For example, a hybrid upflow anaerobic sludge blanket in the presence of microorganisms was used to reduce the levels of COD and TSS in sago wastewater [6]. In another study, Doraisamy et al [17] revealed that an anaerobic hybrid reactor can successfully reduce the influent of organic load content with an optimum hydraulic retention time of 10-20 h. Rashid et al [41] investigated the effect of extended aeration time for the removal of BOD, COD, and TSS from sago wastewater, which was collected from a sago mill in Mukah, Sarawak. In the study, the extended aeration period was able to reduce BOD, COD, and TSS levels to 84%, 88%, and 73%, respectively.…”

The direct discharge of improperly treated effluent from sago industry poses a great threat to water bodies due to the high amount of organic matter. This work investigated ZnO photocatalytic degradation under aerated and non-aerated conditions, and photo-Fenton aiming to reduce the chemical oxygen demand in sago effluent. Photolysis of sago effluent in the presence of ultraviolet irradiation and aeration resulted in 68% of the chemical oxygen demand removal. The results indicate high chemical oxygen demand reductions for different concentrations of sago effluent at 1:10, 1:100, and 1:1000 diluted with distilled water following the ZnO photocatalytic treatment under the aerated conditions. The chemical oxygen demand reductions of 90-95% and 85% were obtained using 3 g/L of ZnO, after 2 h of aerated and nonaerated photocatalytic treatments, respectively, for the sago effluent ratio of 1:1000. On the other hand, the combination of the most concentrated sago effluent at 1:10 and non-aerated ZnO photocatalytic treatment resulted in no appreciable chemical oxygen demand reduction at only 8%. The concentrations of Fe 2+ (10-60 mM) and H 2 O 2 (50-150 mM) greatly influenced the degradation rates of chemical oxygen demand. The optimum parameters of 10 mM of Fe 2+ and 50 mM of H 2 O 2 were able to reduce 97% of the chemical oxygen demand of the 1:1000 sago effluent under the photo-Fenton treatment with 2 h of ultraviolet irradiation. Thus, both ZnO photocatalysis and photo-Fenton can be applied as the possible treatment methods to reduce the chemical oxygen demand in effluent from sago processing.
