Dr. Tadashi Hibino’s research on water purification featured on a TV program in the Philippines

The research result of Pasig River water purification done by Dr. Tadashi Hibino, an associate professor from Graduate School of Engineering, Department of Civil and Environmental Engineering at Hiroshima University, was featured on a TV program in the Philippines.

From 8 to 12 of January 2018, the Granulated Coal Ash (CGA) water treatment system was installed at Estero de San Miguel, Manila, by Hiroshima University (HU) in collaboration with Pasig River Rehabilitation Commission (PRRC) and University of the Philippines (UP).

The Pasig River flows through the city of Manila and connects Laguna de Bay to Manila Bay from East to West stretching for 27 kilometers. The Pasig River has 47 tributaries and canals running complexly and the San Miguel River is one of them. PRRC is an advisory body to the president of the Philippines that aims to purify and restore organically contaminated water in the tributaries and canals of the Pasig River.

PRRC Executive Director Jose Antonio E. Goitia, Dr. Maria Antonia Tanchuling of UP, Dr. Tadashi Hibino of HU, and Barangay 646 Chairman Roel S. Floro’s representative led the ribbon cutting ceremony for the monitoring of Estero de San Miguel’s water quality restoration on January 16, 2018 at Barangay 646 Zone 67 District VI, Manila City.

The GCA, made from fly ash and cement, was confirmed to be an effective material in improving the water and sediment quality in littoral regions for the last 10 years in Japan.

UP and HU collaborated with the PRRC to conduct the research on restoration of the polluted Pasig River tributaries and canals through the use of locally produced GCA. Based on the extensive laboratory tests done at the UP Institute of Civil Engineering and Environmental Engineering Program, it is verified that the locally-produced GCA can be used to restore the water quality of Estero de San Miguel.
