This research focuses on the design and testing of a household wastewater filter that aims to convert domestic wastewater into potable water through the application of multi-stage filtration and disinfection technology based on Polyvinylidene Fluoride (PVDF) membranes. The background of the research is based on the increasing need for clean water, limited access to potable water, and high levels of household wastewater pollution that have the potential to pollute the environment and endanger public health. The system developed in this research is designed as a multi-stage filtration unit, which combines physical, chemical, and biological filtration. The filtration stages include a backwash filter (silica sand, activated carbon, zeolite, and manganese) as an initial filter, followed by a 4-tube Nanotec filter consisting of a sediment filter, activated sand, granular activated carbon (GAC), and cation resin. The final stage uses a PVDF membrane with a very small pore size (around 0.01–0.1 microns) which functions as an ultrafiltration filter to remove pathogenic microorganisms, including Escherichia coli bacteria. The research methods include the design of the tool, assembly of the filtration system, and testing the water quality before and after treatment. The parameters analyzed include physical, chemical, dissolved metal, and microbiological parameters, with reference to the standards of the Minister of Health Regulation No. 32 of 2017. Laboratory testing was conducted to ensure the suitability of the filtered water for clean water and drinking water standards. The results showed that the designed filtration and disinfection system significantly improved the quality of household wastewater. Chemical parameters such as nitrate, nitrite, fluoride, detergent, cyanide, pH, and hardness decreased and were within the quality standard limits after the treatment process. From a microbiological perspective, this system proved highly effective in eliminating pathogenic bacteria, as demonstrated by The removal of E. coli bacteria to 0 CFU/100 mL and a drastic reduction in total xii coliform counts from 4.7 million to 1.8 million. However, the test results also showed that dissolved metal parameters, particularly iron (Fe) and manganese (Mn), still did not fully meet quality standards. Although dissolved iron levels decreased significantly, they remained above the established threshold. Manganese levels even increased after the filtration process, indicating the re-release of metals from the filter media or the media's ineffectiveness in stably binding manganese. Overall, this study proves that the combination of multistage filtration and PVDF membranes is very effective in improving the physical, chemical, and microbiological quality of domestic wastewater, particularly in terms of clarity and microbiological safety. The developed system has great potential as an alternative solution for providing clean and potable water that is economical. This research recommends further development, particularly by adding specific treatment steps for iron and manganese, such as aeration-oxidation, catalytic manganese media, or heavy metal-specific ion exchange resins. With these improvements, the developed filtration system is expected to fully meet national drinking water standards and be widely applied in the community
