SLUDGE VALORIZATION FROM WASTEWATER
TREATMENT PLANT TOWARDS A CIRCULAR ECONOMY
This study aimed to investigate the sludge removed from wastewater treatment plants and various modes of disposal as waste. One way of treating it as fertilizer on agricultural land use, its rich content in nutrients. So then it is necessary analysis and testing before use sludge future presentation. However, this method may be limited by the presence of heavy metals, pollutants microbiological agents, organic and inorganic contaminants. In this article, a variety of sampling analysis, pre-treatment, extraction and methods have been reviewed. Therefore, we consider that an important part of treatment of sludge prior to disposal is the separation of water and sludge volume reduction.
