“…Complexes with a high content of organic materials are broken down into simpler compounds by the anaerobic process's degradation mechanism. The ability of the anaerobic method to handle industrial wastewater with high organic contents has been indicated [11]. The treatment process is less expensive since it uses less energy, creates little sludge, and generates energy that may be used again [12][13][14][15].…”

“…Because it can run at extremely high load levels with the resulting sludge being relatively simple to settle, having a high biomass content, and efficient solid and liquid separation, the UASB reactor provides commercial advantages and the effluent can meet regulatory standards [18]. The HUASB reactor has been used in the research of tofu liquid waste with a PVC attached system and bioball, which produces the highest COD removal of 86.41% and 85.57% and produces 7700 mL and 1510 mL of biogas at 24 hours HRT during the acclimatization process [11].…”

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.

Wastewater of tofu industry contains very high organic content, then anaerobic process is the most suitable for degrading this liquid waste. The hybrid upflow anaerobic sludge blanket reactor (HUASBR) was applied in this study because it has the advantage in ensuring good contact between biomass and substrate where a suspension medium and anaerobic filter are able to withstand more biomass in the attached media. Processing Anaerobic process is carried out with the help of bacteria where bacteria need seeding and acclimatization. Acclimatization is the process of adaptation of microorganisms to wastewater to be treated. This adaptation process is carried out by adding waste water from the smallest concentration to the actual concentration. The purpose of this study is to determine the effect of variations in organic load rate (OLR) on the acclimatization process in removing COD, biogas production in accordance with the pH of the anaerobic degradation process so that the optimal process of the acclimatization process can be obtained. In this study, the acclimatization process took 200 days with variation of OLR in the range of 1.5 - 5.9 kg COD m-3 d-1 at HRT 24 hours and flow rate up (Vup) of 0.08 m/h. The objective of OLR variation was to evaluate acclimatization process on the HUASBR performance during process optimization. The highest biogas production and removal efficiency of COD were achieved in pH range of 6.5 - 7.6. While, the highest COD removal efficiency obtained was 86.57% on the 140th day and biogas production 7700 ml for OLR 4.8 kg COD m-3d-1 at HRT 24 h. Consequently, the optimum OLR for treating the tofu wastewater could be achieved up to 4.8 kg COD m-3d-1 and HRT 24h.
