Abstract

PURPOSE: A specific amount of Ca content is allowed to react with a flocculated active sludge containing Fe and/or Al in specified amounts and formed by the treatment of organic industrial or living waste water, during baking of the sludge, so as to recover the P contents of the sludge as a water-soluble phosphoric acid content.
