Pengembangan Alat Filtrasi Air Metode Funnel Stack dengan Filter Karbon Aktif, Zeolite, Manganese Greensand, dan

Abstract

A study has been conducted on a prototype of a water filtration device, which functions to filter dirty water so that it can become healthy and safe for drinking. The filters used are Ferolite, Zeolite, Silica, and Activated Carbon. The parameters used, aside from color, taste, and odor, are pH levels and TDS. According to the Indonesian Ministry of Health Regulation Number: 416/MEN.KES/PER/IX/1990 regarding water quality standards, the allowed pH for drinking water is 6.5–8.5 and TDS should be below 200. Since this is a prototype, this study only addresses the physical factors of pH and TDS, without involving biological factors, and further research is required. The samples used were taken from the vicinity of Depaero AAU, including wastewater, fresh water, river water, and groundwater. Measurements of pH and TDS were conducted both before and after filtration on the available samples, and the water quality was observed. Subsequently, the effectiveness of each filter in relation to pH and TDS was measured. The Funnel Stack method, or tiered funnel, is able to provide filtration capabilities beyond those of previous methods, reducing the filtration time from over one minute to a matter of seconds. Furthermore, the device is more compact and easier to store. The filtration results are also superior; whereas the earlier method only produced clear water, this funnel method was tested with murky and odorous samples, and it successfully filtered the water to make it clear and odorless.
