The treatment of high-concentration organic wastewater is currently a world problem, such as landfill leachate and digested sludge liquor, in which the concentration of organic matter and ammonia and nitrogen is dozens or even hundreds of times that of municipal wastewater. At present, the dual-memb...

Managed Aquifer Recharge (MAR) applied through infiltration surfaces is a technology that enhances groundwater quality. With this improvement goal, the European project MARadentro was initiated. In this project, a prototype was constructed in Medina del Campo, consisting of two ponds with a surface ...

Inorganic acids are frequently used in the leaching process of end-of-life LIBs due to their low cost and high leaching efficiency. The use of HCl from MDI/polyurethanes production as a leaching medium greatly facilitates the separation of metals through the formation of chloro-metal complexes. Benz...

Lithium-ion batteries have conquered a central role in today’s economy and way of living due to the need for reliable portable devices and the growing electric vehicle industry. This brings along serious ecological issues related to the disposal of these batteries and the prospection of chemical e...

Scheduling pipe replacement is critical for water distribution systems (WDSs) when managing finances and water loss. WDS replacements are often delayed due to high immediate costs without considering long-term environmental consequences. This study is the first to examine a real-world WDS using a no...

Nitrous oxide (N₂O) is a greenhouse gas that can account for more than 70% of direct emissions from Wastewater Treatment Plants (WWTPs). It is primarily produced in aerated tanks within biological treatment systems, such as conventional activated sludge. Activated sludge processes are widely used ...

In an area where there is lack of water supply at home, people travel very far to fetch water. In almost all society this task falls under the women. It is very common to see women carrying 25 and 20 liter Jerry Can on their back or on their head and travel many kilometers from the source like river...

Currently, there is a growing need to increase the efficiency and sustainability of cities, due to population growth and high resources consumption. In the water sector, the water-energy nexus is and remains a very important issue, as one of the most energy-intensive activities in a city is the wate...

Since the implementation of Directive 91/271/EEC, there has been an increase in sludge generation, which necessitates efficient management. The use of sludge for energy recovery and soil improvement is environmentally beneficial, if it does not harm human health or the environment. This use is regul...
