“…According to Asadiya and Karnaningroem [23], this was due to zeolite and activated charcoal being able to adsorb organic substances contained in waste. As organic matter decreases, the COD value also decreases, then the decrease in COD is supported by the absorption capacity of the silica sand used and supported by the role of the pore morphology of the membrane formed [24] as shown in Figure 2. The concentration of COD in the waste is also due to the high oil content, so that with the ultrafiltration treatment of the membrane, macromolecules are retained in the membrane against suspended solids and dissolved solids.…”

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.

“…g. h (1) Where, Ph is the hydrostatic pressure (Pa), ρ is the density of the substance (kg.m3), g is the gravitational velocity (m/s2) and h is the height (m). Next, calculate the flux which is the volume of permeate that passes through a unit area of the membrane in a certain time in the presence of a thrust (pressure) [15]. Systematically the flux is formulated as follows [16].…”

Laundry waste pollution can be handled through the development of filtration with the Gravity Driven Membrane (GDM) method which is designed to follow the criteria of the unloading module design, low polarization control, cost-effective, separation process using thrust in the form of a strong pressure difference. This type of research was an experiment. This study aimed to determine the performance of laundry waste filtration at ultra low pressure using clean water permeability and detergent solution as standardization. GDM filtration performance was tested by measuring permeability at a pressure of 1-10 kPa with two repetitions and long-term filtration for 35 days at a pressure of 6 kPa, the sample was replaced every 7 days without membrane washing. The results showed that as the pressure increases and the filtration time increases, the permeability of laundry waste decreases, this phenomenon is caused by compaction and clogging of the membrane pores (fouling). Permeability decreases from 1 kPa to 10 kPa pressure, the same applies to repetition. Long-term filtration permeability decreased significantly from the first day to the eighth day of filtration respectively 707.9 , 151.7, 115.8, 104.4, 97.5, 107.1, 102.1 and 103. 0 L/m2.hour.bar. On the 9th to 35th day the decrease was stable, this was caused by fouling on the membrane which resulted in the membrane becoming more compact and saturated. GDM filtration can take place for 35 days without washing the membrane with a permeability from the first day of 707.9 and the 35th day of 5.5 L/m2.hour.bar. The best performance of this filtration process lasts until the 9th day

“…Consequently, there was no reduction of KMnO4 in RRWH. Presumably, it was due to the size of KMnO4 molecule is smaller than a void in zeolite and a lower percentage of zeolite (T2) in filter media, and therefore the organic substances particles can pass the filter media (18). Whilst the concentration of KMnO4 in T4 and T5 decreased from 6.5 mgl -1 to 5.2 mgl -1 (19.4%) and from 7.8 mgl -1 to 5.1 mgl -1 (35%) respectively.…”

This study aimed to investigate the quality of the rooftop rainwater harvesting (RRWH) and to treat it for clean water supply alternative of Graha Rektorat building at State University of Malang, Indonesia. Different combinations of zeolite and activated carbon were used as filter media to treat the RRWH. Several parameters have tested to investigate the quality of RRWH based on Permenkes RI No. 416 / MENKES / PER / IX / 1990. Most of the quality of the RRWH met clean water and drinking water standard. However, there were three parameters have to be reduced and required further treatment. The results showed T4 reduced TDS and coliform bacteria by 37% and 36%, while T5 eliminated organic substances (KMnO4) for 35%.
