Throughout the 20th century, prevailing approach toward nitrogen management in municipal wastewater treatment was to remove ammonium by transforming it into dinitrogen (N2) using biological processes such as conventional activated sludge. While this has been a very successful strategy for safeguarding human health and protecting aquatic ecosystems, conversion of its elemental form is incompatible with developing circular economy 21st century. Equally important, sludge process other emerging removal pathways have several environmental technological limitations. Here, we assess that theoretical energy embedded domestic represents roughly 38–48% chemical available whole discharged bodily waste. The current routes not only neglect ammonium, but they can also produce N2O, strong greenhouse gas, emissions comprising equivalent 14–26% overall carbon footprint plants. N2O often exceed related electricity consumption requirements WWTPs. Considering these limitations, there need develop alternative approaches center around recovery from rather than deal "destruction" dinitrogen. Current techniques are applicable at orders magnitude above strength, so new based on physicochemical adsorption particular interest. A pathway proposed allows mainstream through development polymer-based adsorbents. Provided adequate adsorbents corresponding characteristics outlined paper designed brought industrial production, adsorption-based opens perspectives continuous coupled side-stream minimal requirements. This bring forward an effective resource-oriented upgrade fate urban water without generating hidden externalized costs.

Electrochemically mediated precipitation of phosphate minerals for phosphorus removal and recovery: Progress and perspective

Water Research, Journal Year: 2021, Volume and Issue: 209, P. 117891 - 117891

Phosphorus (P) is an essential element for the growth and reproduction of organisms. Unfortunately, natural P cycle has been broken by overexploitation ores associated discharge into water bodies, which may trigger eutrophication bodies in short term possible shortage soon. Consequently, technologies emerged to recover from wastewater mitigate pollution exploit secondary resources. Electrochemically induced phosphate precipitation merit achieving recovery without dosing additional chemicals via creating a localized high pH environment near cathode. We critically reviewed development electrochemically systems toward removal over past ten years. summarized discussed effects pH, current density, electrode configuration, matrix on performance electrochemical systems. Next ortho P, we identified potential illustrated mechanism non-ortho compounds combined anodic or anode-mediated oxidation cathodic reduction (precipitation). Furthermore, assessed economic feasibility methods concluded that they are more suitable treating acidic P-rich waste streams. Despite promising potentials significant progress recent years, application at larger scale requires further research development. Future work should focus evaluating system's under long-term operation, developing automatic process harvesting deposits, performing detailed life-cycle assessment.
