A Proposed Solar Water Distiller for Coastal Houses in the Philippines

Vol.3, No.1D

Abstract

Solar Water Distillation evaporates water using solar energy, with the condensate collected in the same closed system. Water purification can be accomplished by a variety of methods, including distillation. Solar radiation can be used to generate heat. (Lightowerpro, n.d.) This type is still a passive solar distiller that only needs sunshine. This type is still a passive solar distiller that only needs sunshine. Solar Water distillers or solar stills are usually used in remote areas with limited access to freshwater. The study's primary focus is on coastal parts of the Philippines that lack safe and sustainable water sources, with household water supplies for drinking and cooking coming from various natural bodies such as seawater, rivers, springs, lakes, etc. Northern Samar, Sarangani, Lanao Del Sur, Eastern Samar, Maguindanao, Zamboanga del Norte, Negros Oriental, and Sultan Kudarat are the provinces involved. This study utilized the quantitative-experimental research method while utilizing purposive and snowball sampling. The statistical treatment used for this study was a T-test to determine the difference between the assessments of the two groups of respondents. 

Using the questionnaire as the research instrument, the survey was used to assess the level of acceptability of the Solar Water Distiller in terms of the construction materials, distilling mechanism, design and procedure, and presentation using statistical analysis. The respondents of the study are composed of the study are 5 Mechanical Engineers and 15 Mechanical Engineering Students. The following procedures were undertaken in developing the model: Preparing the Floor plan with different dimensions, making the body of the solar water distiller, putting water, placement in a sunny place, and presenting and testing the project. The results of the study in terms of construction materials, distilling mechanism, design and procedure, and presentation are highly acceptable. The overall mean of the Mechanical Engineers is 3.71, interpreted as Highly Acceptable. The overall mean of the Mechanical Engineering Students is 3.55, interpreted as Highly Acceptable. The t-computed was 3.44, the t-critical was 2.552, the t-computed > t-critical. It indicates a significant difference between the assessments of the two groups of respondents. The study indicates that using the right materials, such as toughness and quality, can help the project meet its goals. It also shows that using the right funds, processes, and floor layout can help the project succeed. This study still has some flaws, including methodologies, materials, and designs, which could lead to further research.
