Published: April 9, 2022

Recently, every industry has been working to achieve carbon neutrality, and the wastewater sector is no exception. However, little research focuses on accounting of treatment roadmap neutrality. Here, systematically perform accounting, we provide a sketch that describes three boundaries system propose neutrality far beyond plant boundary. Moreover, identify direct indirect emissions treatment. In addition CH4 N2O, fossil CO2 from should be included in set accurate guidelines. Next, technologies assist achieving carbon-neutral both within-the-fence plants boundary are summarized. All measurements energy recovery, resource water reuse contribute reaching this goal. The concepts identified. Successful cases self-sufficiency may not Meanwhile, recovery methods encouraged, especially produce carbon-based materials. Ultimately, trend preference for decentralized sewage pinpointed, systematic thinking urban infrastructure layout as whole advocated.

Urban Wastewater as a Source of Reclaimed Water for Irrigation: Barriers and Future Possibilities

Environments, Journal Year: 2023, Volume and Issue: 10(2), P. 17 - 17

Published: Jan. 25, 2023

Water resources are under pressure worldwide, resulting in scarcity and deterioration of freshwater quality. According to European directives, we could reduce the on water urban areas by increasing reuse treated wastewater, reducing impact bodies, promoting recycling through multiple uses wastewater. Besides need address supply challenges, wastewater treatment systems show environmental stewardship innovative practices. Using reclaimed for agricultural irrigation is gaining interest because drought conditions experienced Europe over past few years. Furthermore, using may help restore nutrients (N P) natural biogeochemical cycles. This review highlights importance reuse, current legislation, existing technologies implement meet minimum requirements produce irrigation.

A review of the state-of-the-art wastewater quality characterization and measurement technologies. Is the shift to real-time monitoring nowadays feasible?

Journal of Water Process Engineering, Journal Year: 2024, Volume and Issue: 60, P. 105061 - 105061

Published: March 12, 2024

Efficient characterization of wastewater stream quality is vital to ensure the safe discharge or reuse treated (WW). There are numerous parameters employed characterize water quality, some required by directives (e.g. biological oxygen demand (BOD), total nitrogen (TN), phosphates (TP)), while others used for process controls flow, temperature, pH). Well-accepted methods assess these have traditionally been laboratory-based, taking place either off-line at-line, and presenting a significant delay between sampling result. Alternative can run in-line on-line, generally being more cost-effective. Unfortunately, often not accepted when providing information regulatory bodies. The current review aims describe available laboratory-based approaches compare them with innovative real-time (RT) solutions. Transitioning from RT measurements means obtaining valuable data, avoiding time delays, possibility optimize (WW) treatment management. A variety sensor categories examined illustrate general framework in which applications replace longer conventional processes, an eye toward potential drawbacks. enhancement be achieved through employment advanced soft-sensing techniques Internet Things (IoT), coupled machine learning (ML) artificial intelligence (AI).

Water and wastewater infrastructure is a major energy consumer an important source of global greenhouse gas emissions: on average, 10.6 kg CO2/m3 water consumed. The European Environment Agency in 2019 estimated these emissions from treatment operations Europe alone at over 25 MtCO2eq. Increased demand (in terms volumes quality) the sector raises expectations future increases if appropriate measures will not be undertaken. Many companies utilities associations have been or are developing plans to achieve net zero industry-wide basis by 2050, some cut 50% last ten years. About half energy-related facilities could significantly abated applying existing technologies, close 95% this objective achieved negative cost with proper innovation strategies.
