The cost reduction effect trial calculation of the phosphorus collection facilities by waste alkali use

Abstract

 In order to plan cost reduction at the time of performing the phosphorus collection by an ashes alkaline extraction method using the sewage sludge incineration ashes and waste alkali which are generated in Iwate, the effect trial calculation in the various reduction techniques was performed.
 As a result, it has been understood that the further cost reduction of phosphorus collection facilities was possible by utilizing crazes for surplus as a heat source for the heating.
