A review on the integration of mainstream P-recovery strategies with enhanced biological phosphorus removal

Water Research, Journal Year: 2022, Volume and Issue: 212, P. 118102 - 118102

Published: Jan. 18, 2022

Phosphorus (P), an essential nutrient for all organisms, urgently needs to be recovered due the increasing demand and scarcity of this natural resource. Recovering P from wastewater is a feasible promising way widely studied nowadays need remove in treatment plants (WWTPs). When enhanced biological removal (EBPR) implemented, innovative option recover supernatant streams obtained mainstream water line, then combine it with liquor-crystallisation recovery processes, being final product struvite, vivianite or hydroxyapatite. The basic idea these P-recovery strategies take advantage ability polyphosphate accumulating organisms (PAO) increase concentration under anaerobic conditions when some carbon source available. This work shows technologies reported so far, both continuous sequenced batch reactors (SBR) based configurations. amount extraction, as key parameter balance efficiency maintenance EBPR system, should first design criterion. maximum value long-term operation adequate extraction ratio would around 60%. Other relevant factors (e.g. COD/P influent, additional source) operational parameters aeration, SRT, HRT) are also discussed.

Advances in Nitrogen-Rich Wastewater Treatment: A Comprehensive Review of Modern Technologies

Sustainability, Journal Year: 2024, Volume and Issue: 16(5), P. 2112 - 2112

Published: March 3, 2024

Nitrogen-rich wastewater is a major environmental issue that requires proper treatment before disposal. This comprehensive overview covers biological, physical, and chemical nitrogen removal methods. Simultaneous nitrification–denitrification (SND) most effective in saline water when utilizing both aerobic anoxic conditions with diverse microbial populations for removal. Coupling anammox denitrification could increase rates reduce energy demand. Suspended growth bioreactors effectively treated COD/N ratios demonstrated resilience to low C/N ratios. Moving biofilm exhibit reduced mortality rates, enhanced sludge–liquid separation, increased efficiency, stronger biological structures. SND studies show ≥90% total efficiency (%RETN) setups, Defluviicoccus, Nitrosomonas, Nitrospira as the main communities, while anammox–denitrification achieved %RETN of 77%. Systems using polyvinyl alcohol/sodium alginate medium showed ≥ 75%. Air-lift reflux configurations exhibited high %RENH4, reducing costs minimizing sludge formation. Microwave pretreatment high-frequency electric fields be used improve %RENH4. Adsorption/ion exchange, membrane distillation, ultrafiltration, nanofiltration promise industrial treatment. AOPs sulfate-based oxidants eliminate compounds from wastewater. Tailoring proposed treatments cost-effective removal, optimizing interactions, analyzing techno-economics emerging technologies are crucial.

Critical Review of Electro-kinetic Remediation of Contaminated Soils and Sediments: Mechanisms, Performances and Technologies

Water Air & Soil Pollution, Journal Year: 2021, Volume and Issue: 232(8)

Published: Aug. 1, 2021

Abstract Remediation of contaminated soil and sediment is important for improving the eco-environmental quality. Electro-kinetic remediation (EKR) an environmentally friendly technology to migrate remove pollutants from matrix. This paper analyses mechanism performance EKR heavy metals, organic pollutants, compound pollutants. Moreover, effect optimizing individual through pre-treatment (adding acid/oxidant/co-solvent/surfactant, stirring, heating, etc.), electrode optimization (exchange electrode, anode approximation, matrix, applying multi-technology combination (electro-kinetic permeable reaction barrier/Fenton/ion, exchange membrane/ultrasonic/electrolyte enhancement, etc.) was evaluated. Factors including incomplete separation variation in physico-chemical properties microstructure soil/sediment, difficulties situ practice have restrained field application EKR. To solve above technical challenge, integrated based on pollutant separation, followed by separated contaminant treatment, subsequent valuable elements recovery proposed.
