Use of residues from Eucalyptus Globulus as biosorbents for cadmium removal
(Corresponding) Hansen H., Gutierrez C., Alarcon J., Lazo A., Hansen M., Lazo P., Ortiz R.
Topic:
Wastewater treatment
The present work studied the removal of cadmium from aqueous solutions by a series of batch sorption experiments using Eucalyptus Globulus bark and seeds as biosorbents. Both biosorbents showed good results in cadmium removal. The best results were obtained when working with a particle size < 75...Read more
Application of electrochemical peroxidation with nanoscale zero-valent iron particles (nZVI) for selenium removal from oil refinery wastewater
Hansen M., Gutiérrez C., Lazo A., Lazo P., (Corresponding) Hansen H.
Topic:
Wastewater treatment
This study uses the electrochemical peroxidation process to remove selenium in combination with nanoscale zero-valent iron particles (nZVI) as the iron source. Also, experiments with just the addition of the nZVI doses without current application were carried out. The nanoparticles were synthesized...Read more
Selection of bacterial strains to bioaugment granular sludge and improve the removal of recalcitrant pollutants
(Corresponding) Carlier J., Lara-Moreno A., Ngonyani A., Martins A., Villagomez A., Igbodo B., Cox C., Ismail F., Marín-Beltrán I., Palma T., Costa M.
Topic:
Wastewater treatment
Several advantages are gained by the use of granular sludge in wastewater treatment plants (WWTP), such as higher biomass retention, faster settling properties, lower energy costs and smaller operational land space. However, relatively few studies have been carried out on the biodegradation of...Read more
Development and Application of a novel anaerobic/aerobic/anoxic process in municipal wastewater treatment utilizing intracellular carbon sources
Gao X., (Corresponding) Peng Y.
Topic:
Wastewater treatment
Municipal wastewater treatment plants (WWTPs) face a significant challenge in controlling treatment costs while meeting increasingly stringent wastewater discharge standards. To address this challenge, A novel anaerobic/anoxic/aerobic (AOA) process has been proposed. In this study, long-term...Read more

Sustainable and Cost-effective Approach for Treatment of Plating Industrial Wastewater Effluents
(Corresponding) Boguniewicz-Zablocka J., Naddeo V., (Corresponding) Corpuz M.
Topic:
Heavy metals in the environment
The wastewater resulting from the plating industry contains high contents of toxic metals, such as chromium, which is a serious threat to the environment due to its cumulative effects and non-degradability. Several methods have been actively investigated to remove heavy metal ions from aqueous...Read more

Effect of plant species on the performance of vegetated buffer strips to treat agricultural runoffs
(Corresponding) Markoulatou E., Fountoulakis M.
Topic:
Water treatment
Vegetated buffer strips (VBS), have been recognized as the most common management practice for mitigating pollution caused by agricultural runoff. They serve a transitional zone between agricultural fields and receiving waters. In this study, two VBS planted with aromatic plants and one unvegetated...Read more
Technologies for the Removal of Microplastics from Wastewater: A Short Review
(Corresponding) Corpuz M., Buonerba A., Napodano P., Hasan S., Choo K., Zarra T., Belgiorno V., Naddeo V.
Topic:
Microplastics in water treatment: fate, toxicity assessment and removal technologies
One of the major routes of microplastics (MPs) to the environment is through the wastewater treatment plants’ (WWTPs) discharge to water bodies. Due to their dimensions (< 5mm), MPs tend to be ingested by aquatic species, and eventually, may cause adverse impacts on the environment and to human...Read more
