Abstract
PURPOSE: An economical filtering method wherein water to be treated is made to go upward in a filtering tower, and contaminated materials are filtered through filtering sand in the filtering tower; while the contaminated filtering sand is removed from the bottom of the tower, is cleansed, then is returned to the top of the layer of the filtering sand for repeated use.
