“…The O-H stretching vibrational peak related to Ti-OH bond was observed, indicating the absorption of water by hydrophilic TiO2 [18]. Meanwhile, the O-H bending vibrational peak indicated the presence of water content in the sample [20]. The presence of O-H vibration bonds indicated the presence of water molecules in the TiO2 sample.…”

“…As stated by Fadli et al [16], PES polymer does not have O-H bonds in its structure, therefore, the presence of O-H structure could be obtained from the use of aquades as a coagulant during the manufacturing process or due to the sample being analyzed in a wet state using FTIR. Furthermore, the presence of Ti-O vibrational bonds is a characteristic of TiO2 [20]. The results of equation (2) show that the 15% PES membrane has a higher flux compared to the 20% PES membrane because the dense layer on the 15% PES membrane is thinner than the 20% PES membrane, so the flux through the membrane is higher [3].…”

Restaurant liquid waste contains elevated pollutant levels and is commonly discharged directly into the environment, leading to adverse impacts on ecosystems and aquatic life. The traditional methods for processing such wastewater often involve extensive land usage and complicated operations, posing challenges for effective treatment. Therefore, there is a need for a more practical technology to manage restaurant liquid waste, and one promising approach is the utilization of membrane technology for wastewater treatment. In this study, the researchers employed a combination process of multilevel filters with downflow flow and PES membrane ultrafiltration to treat the restaurant liquid waste. The multilevel filter comprised several layers of filter media, including silica sand, activated carbon, zeolite, and gravel, with specific thicknesses on a PVC pipe. For the PES membrane, two different concentrations were tested: 15% and 20% PES. To evaluate the efficiency of the treatment process, pollutant parameters such as pH, TSS (Total Suspended Solids), COD (Chemical Oxygen Demand), and turbidity were measured. The results indicated significant pollutant reduction: pH levels could reach 6.9, TSS degradation achieved up to 98.37%, COD degradation up to 88.14%, and turbidity degradation up to 97.03%. Based on the outcomes, the most effective treatment for converting restaurant wastewater into clean water involved the combined use of multilevel filters and a 20% PES membrane ultrafiltration system.
