DOST Secretary Mario G. Montejo (2nd from left) turns over 200 units of the DOST innovation on water treatment system called the Portable Ceramic Water Filter (Pitcher Type) to recipients represented by staff of the Cultural Affairs Department and Department of Social Welfare and Development of Vigan City, Ilocos Sur during the recent Northern Luzon Cluster Science and Technology Fair held on September 1, 2015 at the Tadena Hall, University of Northern Philippines (UNP). Witnessing the turnover is Dr. Gilbert R. Arce (left), UNP president. Through the principle of gravity, the two-liter capacity water filter can sift tap or deep well water using red clay with nanotechnology silver coating as the main filtering agent. Red clay is abundant in the Ilocos region. To date, the ceramic water filter system is in use in the Cordillera Administrative Region, Cagayan Valley, and Eastern Visayas. It will soon be introduced in other parts of the country. (S&T Media Service/Text by Rodolfo de Guzman and photo by Gerry Palad)
