ABSTRACT
A water filter is a device that removes impurities from water by means of a fine physical barrier. In most cases, filters are being used to remove TSS (Total Suspended Solids) from water for different purposes. There are many types of water filters but common water filters used at households are called domestic water filters. These filters can be attached directly to a tap, attached to the domestic water supply before the tap, or at the point of use when traveling.
The aim of this study is to measure how much total suspended solids can carbon and membrane water filters filter per volume of water (milligrams per liter).
The weight of each filter was recorded prior to filtering. Then each filter was made to filter one liter of water from the research lab of PSHSWV and were dried afterwards. Then the weight of each filter after drying was recorded. The difference in their weight would represent how much TSS they were able to filter.
The carbon water filters and membrane water filters were able to filter a mean amount of 611.547 milligrams per liter and 127.935 milligrams per liter of total suspended solids, respectively. Each water filter was able to filter a different amount of total suspended solids. The carbon water filters had a greater gain in weight compared to the membrane filters.
