Recent studies on anaerobic digestion highlight the benefits of two-phased systems, which enhance digestate stability and sanitation, increase organic loading rates (OLR), boost methanogen activity for higher methane production, improve volatile solids (VS) reduction efficiencies, and enhance digest...

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 ...

1. Introduction Hydrogen sulfide (H₂S) poses significant challenges in sewer systems, contributing to odor, corrosion, and safety risks. Traditional chemical treatments, while effective, often rely on costly and non-sustainable materials. This study explores an innovative circular economy approach...

As global food production dominates freshwater consumption and nutrient discharge regulations tighten, there is a need to investigate novel circular water solutions at applied scale. In the Netherlands, the greenhouse horticulture sector is required to achieve (nearly) zero liquid discharge by 2027....

Facing changing conditions like climate change, water-stressed regions are exploring alternative water supply options, including agricultural and urban reuse. While required technologies are available, highly flexible and demand-driven management strategies for water reuse in urban and agricultural ...

The increasing global water scarcity - exacerbated by climate change - requires innovative and sustainable solutions. This study presents a novel adsorption-based water harvesting device designed to capture water from atmospheric air. The device utilizes sorption materials, operating in two differen...

Stricted legislation and a heightened emphasis on environmental stewardship are transforming conventional wastewater treatment plants (WWTPs) into greener and more efficient biorefineries, producing valuable bioproducts that are increasingly prevalent in society. Notably, the recent wastewater treat...

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...

Industry is one of the largest water users in Europe next to agriculture and households. Circular water concepts are already implemented in industry, but the European Commission (EC) is giving specific attention to ‘Water Smart Industrial Symbiosis (WSIS)’ in which economic value and increased s...

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...
