Special Issue Information

Dear Colleagues,

Water scarcity is a significant problem in many societies, to which the reuse of wastewater after appropriate treatment could offer a sustainable solution. Owing to recent advances in technologies for wastewater treatment and reuse, wastewater effluents with consistently high quality can be achieved, which can then possibly be reused in the agriculture, industry, and urban sectors.

This Special Issue is intended to cover existing techniques which are used to remove different contaminants from wastewater. Moreover, sustainable solutions for wastewater management will also be covered, with an emphasis on agricultural reuse and irrigation technologies. The implications of wastewater reuse in the soil–plant system and their potential solutions will also be a focus of this issue.

To cover this theme, original research papers, review articles, and short communications on the following topics are invited:

  • Wastewater treatment techniques;
  • Monitoring and fate of contaminants in wastewater;
  • Irrigation systems and practices for the reuse of wastewater in agriculture;
  • Reuse of wastewater in industrial and urban sectors;
  • Implications of wastewater reuse and contaminants therein on soil quality and plant growth;
  • Sustainable management of pollutants in wastewater irrigated/contaminated soils;
  • Management of nutrients and fertilizers using treated wastewater;
  • Recovery of nutrients and other resources from wastewater.

The presence of potentially toxic metals in water causes a strong impact on environment and human health. In this study, activated biochar was produced by using chemical oxidation method from wheat straw as natural adsorbent and was employed for heavy metals competitive remediation. The morphology, structure, and chemical properties of biochar before and after adsorption were characterized by FTIR, XRD, SEM and EDX mapping techniques. The competitive adsorption efficiency of adsorbent for divalent cadmium (Cd) and lead (Pb) from contaminated water was investigated by using wide range of several initial metal concentration, contact time and pH. Maximum adsorption of Cd(II) and Pb(II) was found in the pH range of 6–8. The adsorption capacity for Cd(II) and Pb(II) was 8.85 and 9.03 mg/g, respectively. Thermodynamics parameters and kinetic models were applied to adsorption data. The isotherm data followed Langmuir model, corresponding to monolayer adsorption of the two ions in the contaminated water. The kinetic data followed the pseudo 2nd order kinetics model, which authenticates the chemisorption nature. The thermodynamic study indicated that Cd adsorption is a spontaneous exothermic process while Pb adsorption is an endothermic process. Mineral precipitation, surface complexation, and cation-π interactions are the major remediation strategies for Cd(II) and Pb(II). Full article
