“…Adding an anaerobic phase in conventional pre-treatment reactors provides time for nitrification and denitrification microorganisms to reduce the total N parameter in wastewater effectively [9] [29]. The balanced anaerobic and aerobic phases will help the nitrification cycle (conversion of ammonia nitrogen to nitrate) and denitrification (conversion of nitrate to nitrogen gas) to occur ideally [10] [11]. Based on this analysis, the addition of an anaerobic phase at the beginning of SBR is considered important as it can remove nitrate and phosphate pollutants more optimally.…”

Restaurant wastewater poses a significant environmental challenge, especially concerning the removal of oil and grease, which is known to be highly persistent. To tackle this issue, the research utilized a Lactobacillus bacteria consortium to effectively degrade oil and grease present in the wastewater. The Lactobacillus bacteria consortium was applied in an aerobic environment within the Grease Trap, while various treatment conditions, such as hydraulic retention time (HRT) and aeration rate, were evaluated to determine the optimal settings for the SBR. By employing this combined pre-treatment and SBR approach, distinct aerobic and anaerobic conditions were created, leading to significant removal of pollutant parameters by microorganisms. Remarkably, the study's findings demonstrated that at a 24-hour retention time and a 14 L/minute aeration rate, the Lactobacillus bacteria consortium achieved an impressive 97.42% removal of oil and grease, compared to only 84.54% removal by the Grease Trap without bacteria. The pretreatment of the Lactobacillus bacteria consortium led to even higher reductions in other pollutant parameters. By harnessing the power of the Lactobacillus bacteria consortium and employing the SBR in combination with pre-treatment, this approach holds great potential for addressing the persistent challenge of oil and grease removal in restaurant wastewater and improving overall water quality.

“…The acclimatization process is completed when the COD removal reaches 50% and is constant. When COD removal has reached 50% and has remained steady, the acclimatization process is complete [Hendrasarie et al 2021;Zao et al 2021].…”

“…This is because the stirring speed can speed up the homogeneity of the liquid during the mixing phase. As a result, the faster the stirring speed, the less time it takes to achieve homogeneity in the mixture [Hendrasarie et al 2021]. The SBR was also measured without an impeller, using only a diffuser, which was an important aspect of this research.…”

The characteristics of the wastewater produced by the tofu industry are high viscosity, slipperiness, and foaming resulting from the continuous fermentation of the tofu bacteria. This made it difficult to reduce the organic content of tofu wastewater, namely biological oxygen demand (BOD 5 ), phosphate (PO 4 ), and Total Nitrogen. A wastewater processor that is designed to handle dense and slippery tofu wastewater is known as a Sequencing Batch Reactor. The impeller is used to create turbulent flow, resulting in more evenly distributed DO, which is difficult to distribute due to the viscous tofu wastewater. The SBR was operated with a hydraulic retention time (HRT) of 24, 36, and 48 hours and an impeller stirring speed of 50, 100, and 150 rpm. The results of the research found that there was an effect on the stirring speed of the impeller and that the low stirring speed of the impeller was not optimal. HRT that was regulated in the SBR cycle has affected the performance of the bacteria. Pseudomonas sp. was found in this study and Bacillus sp., which can degrade up to 90% of phosphate and nitrate.
