Wastewater Treatment, Valorization and Reuse

Dear colleagues,

Water resources management in general and wastewater treatment, valorization, and reuse in particular are currently being considered as important worldwide challenges. In this context, the 2030 United Nations Agenda for Sustainable Development Goals (UN-SDGs) aims to improve water quality by reducing pollution, eliminating dumping, and minimizing the release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally. Nowadays, the paradigm of wastewater management is shifting from ‘treatment and disposal’ to ‘reuse, recycle, and resource recovery’. The main benefits of this new concept concern not only human and environmental health, food, and energy security but also climate change mitigation. Hence, in the context of a circular economy, whereby economic development must be balanced with natural resources preservation and environmental sustainability, wastewater can be considered an abundant source of precious and sustainable resources.

The main included themes in this Special Issue include but are not limited to the following:

• Wastewater treatment technologies;
• Innovative technologies for the removal of emerging pollutants;
• Decentralized wastewater treatment systems;
• Sewage bio-solids management (methanisation, composting, land application, etc.);
• Resources (struvite/energy) recovery from wastewater;
• Reuse of recovered resources from wastewater;
• Reuse of reclaimed wastewater (agriculture, groundwater recharge, industry, and others);
• Wastewater reuse policy;
• Wastewater reuse and monitoring.
