VALENZUELA CITY • Pasig River basin is now facing serious water pollution caused by the continuous direct inflow of 15°0'N

15°0'N enormous amount of sewage which stems from the recent rapid population growth which surpasses 14°41'0"N Philippines・Metro 14°41'0"N the environment infrastructure development. METRO MANILA CITY

Clusters 1 , 7, 8, 9 CITY the past more than 15 years, but drastic improvements have not yet been achieved.

Hi-Beads • Purification by mineral will create an environment, in which microorganisms decompose and circulate organic matter which can be further utilized by animals and plants. • Reduction of the deposition amount of the organic mud and hydrophilic improvement can be expected by the progress of the weight loss and separation of organic matter through purification. （Source：Brochure of Chugoku Electric Power Co., Ltd.)
