Abstract

PURPOSE: A specific amount of an alkali component is allowed to react with a flocculated active sludge formed by treatment or organic industrial or living waste water and containing Ca and/or Al in amounts not exceeding specified amounts, before (during or after) baking of the sludge in order to recover a phosphorous content in the waste water as water-soluble phosphates.
