Project Overview<\/strong><\/h2>\n\n\n\n

Bohol Island, a prominent tourist destination in the Philippines, encounters freshwater lacks during the completely dry period. Local groundwater is impacted by seawater intrusion, with TDS values as high as 30,000\u2013 35,000 mg\/L, while neighborhood alcohol consumption water need to adhere to the Philippine National Drinking Water Requirement (PNSDW: TDS \u2264 800 mg\/L). This job aims to develop a trustworthy seawater desalination system<\/strong><\/a> to attend to the everyday water needs of a 200-person neighborhood.<\/p>\n\n\n\n
