Evaluation of Makeshift Water Filter and Distilling Device for Water Purification

Abstract

INTRODUCTION

Nowadays, water, especially in the Philippines, is more likely to be polluted making it harmful for the individuals. By this, Ambulkar, Lanfair and Schroth (2018) stated that methods of purifying water will remove biological contaminants, organic and inorganic materials in water; including the process of distillation and deionization to produce potable water. Thus, each method for water purification was addressed individually and it lacks studies thatfocus on the combination of any two methods. Hence, this study will fill in the gap by evaluating the makeshift water filter and distilling device for water purification.

METHODS

This study developed a makeshift water filter and distilling device in order to evaluate its effectiveness for producing purified water. The water samples used were gathered from Brgy. Kaytapos, Indang, Cavite then brought to Cavite Water and Wastewater Testing Laboratory (CWWTL) for the physical, chemical and microbiological analysis in terms of turbidity, pH level and Total Coliform count before and after it underwent the device. The results provided by the CWWTL for each property were used for the computation whether the null hypothesis was accepted or rejected using the paired T-test for statistical treatment.

RESULTS

Results from the CWWTL showed that there was a significant change on the physical, chemical, and microbiological properties of the river water before and after it was purified by the device in terms of turbidity, pH level, and Total Coliform count. First, the turbidity of the river water dropped from 8.1 NTU to 7.4 NTU after went through the device. Next, the pH level also decreased from 8.1 to 7.4 too. Finally, the Total Coliform count similarly diminished from 170 MPN to less than 1 MPN or equals to zero.

Computing for the significant difference between the properties of the rainwater before and after it undergoes the device in terms of turbidity, pH level, and Total Coliform count, T-test was used. It obtained a T-value of 0.82 which implied that there is a significant difference between the properties of the river water before and after it undergoes the device.

DISCUSSIONS

Specified by the computed results, the makeshift water filter and distilling device was proven to be effective to be used for water purification. Therefore, the researchers concluded that the device developed functioned properly on how it was meant to be. Consequently, this study achieved its target which is to provide clean and safe water for the usage of each individual.
