Static and dynamic investigations on leaching/retention of nutrients from raw poultry manure biochars and amended agricultural soil
( MDPI , 2021 , Article)In this study, nutrients release/adsorption from/by raw poultry manure-derived biochar produced at a pyrolysis temperature of 600 °C (RPM-B) was assessed under static and dynamic conditions. Batch sequential leaching ... -
Use of Electrical Resistivity Tomography to Study the Impact of Long-Term Application of Sewage Sludge: Case Study of Oued Souhil Experimental Station, Nabeul (Tunisia)
( Springer , 2022 , Conference Paper)Soil salinization following repetitive applications of sewage sludge (S.S.) is a major environmental impediment with severe adverse impacts on agricultural productivity and sustainability, particularly in arid and semiarid ... -
Use of lignite as a low-cost material for cadmium and copper removal from aqueous solutions: Assessment of adsorption characteristics and exploration of involved mechanisms
( MDPI , 2021 , Article)Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ... -
Use of waste marble powder for the synthesis of novel calcium-rich biochar: Characterization and application for phosphorus recovery in continuous stirring tank reactors
( Elsevier , 2023 , Article)This study investigates—for the first time—the synthesis of a novel Ca-rich biochar (N–Ca–B) and its potential use for phosphorus (P) recovery from both synthetic solutions (SS) and treated urban wastewater (TUW) in a ... -
Valorization of salt post-modified poultry manure biochars for phosphorus recovery from aqueous solutions: investigations on adsorption properties and involved mechanism
( Springer , 2021 , Article)In this research work, raw poultry manure biochar (RPM-B) was post-modified by two metal salts and then evaluated for P recovery from aqueous solutions in batch mode. The modified biochar characterization showed that RPM-B ... -
Variation of soil properties with sampling depth in two different light-textured soils after repeated applications of urban sewage sludge
( Elsevier , 2021 , Article)Semi-arid agricultural soils have increasingly been subjected to urban sewage sludge (USS) applications due to accelerated soil depletion and shortages in manure supply. Research studies addressing USS reuse have mostly ...
