Secondary Use of Sewage Sludge, Research on Its Morphology and Physical and Chemical Properties

Abstract

The findings of comprehensive studies on morphology, physico-chemical properties of sewage sludge, as well as practicalities of its application have been introduced. The sewage sludge used for the research came from the purification facilities of Volzhsky after the preliminary treated by the enzymatic-cavitation method. The morphology and structure of the processed sewage sludge have been determined by scanning electron microscope investigation and X-ray phase analysis. The chemical composition of the processed wastewater sludge have been and tested as an organic fertilizer in the cultivation of the false saffron.
