Striking a Balance: Decentralized and Centralized Wastewater Treatment Systems for Advancing Sustainable Development Goal 6

Wastewater Treatment Systems This perspective provides quantitative assessments of wastewater treatment systems. In densely populated areas, CWTS offers advantages of scale, while in low-density regions, DWTS offers scope benefits. While centralized systems benefit from scale economies, decentralized setups capitalize on compactness, offering multifunctionality and flexibility. Moreover, decentralized systems require less land, and their modular design allows for easy upgrades and scaling. More details can be found in article number 2400097 by Muhammad Ali, Pascal E. Saikaly, and co-workers.
