PHYSICOCHEMICAL CHARACTERIZATION AND REGULATORY ASSESSMENT OF SEWAGE SLUDGE FROM AÏN EL BEÏDA (ALGERIA): FOCUS ON TRACE METAL ELEMENT DISTRIBUTION AND COMPLIANCE
The agricultural spreading of sewage sludge requires a precise assessment of trace metal elements (TME) to ensure soil protection. This preliminary study presents the first physicochemical characterization of sludge from the Aïn El Beïda wastewater treatment plant, based on two samples collected one year apart (S1, S2)...
