WATER CLEANING MATERIAL, WATER CLEANING BODY USING THE SAME, AND METHOD OF CONSTRUCTING THE SAME

摘要

PPROBLEM TO BE SOLVED: To inexpensively provide a water cleaning material excellent in a water cleaning performance, a conveying performance and stability after installation. PSOLUTION: The water cleaning material is composed by including a filter medium and a heavy object formed by connecting a plurality of porous concretes roughly in parallel with intervals respectively in a water permeable bag material. The porous concrete presents a solid longitudinal shape and the filter medium can be granular charcoal. By the configuration, the water cleaning material is not made to flow by a water flow after installation, and cleaning action by the filter medium and the absorbency of the porous concrete and the cleaning action by microorganisms inside the porous concrete are simultaneously achieved.
