An Investigatory Study of Water Filtration

Abstract

Water filtration project is a process that can remove unwanted substances in water using materials such as pebbles, sand, and charcoal and turn it into water that can be used on everyday habits and can eventually be drunk. Charcoal is activated to remove chlorine. Pebble is used to trap and strain particles in the water. Sand is naturally occurring granular materials composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. This study utilized a quantitative analysis method of research. It also utilized a questionnaire to test the level of acceptability of the water filtration process in terms of color, suspended particles, and usefulness and assessed by 5 Science Experts and 5 Science Teachers of Bestlink College of the Philippines. To determine the level of acceptability of the water filtration process, the researchers used a t-test to test the significant differences between the assessment of the Science Experts and Science Teachers at the level of significance of α= 0.01 and the degree of freedom of 8. The level of acceptability of the water filtration process in terms of color, suspended particles, and usefulness is moderately acceptable as assessed by the Science Experts and Science Teachers. There is no significant difference between the assessment of the Science Experts and Science Teachers on the level of acceptability of the water filtration process in terms of color, suspended particles, and usefulness. The Science Teachers said that the color and suspended particles were acceptable but it is not advisable for drinking. The Science Experts said that there are many tests that we need to conduct to know if it is potable and safe. The level of acceptability of the water filtration process is rejected. This study was connected to another study that used the same ingredients as pebbles, sand, and charcoal. This study was not as effective as we used normal charcoal to filtrate the water. Another study that used activated charcoal was reliable. The flaws of the study were acknowledged and the future researchers were advised to research more effective ingredients to filter the water.
