Exploring resource recovery potentials for the aerobic granular sludge process by mass and energy balances – energy, biopolymer and phosphorous recovery from municipal wastewater

Abstract

<p>Mass and energy balances are an excellent tool to explore the integration of resource recovery technologies into wastewater treatment processes and reveal recoverable resource quantities and occurring trade-offs at an early process design stage.</p>

Full-scale aerobic granular sludge for municipal wastewater treatment – granule formation, microbial succession, and process performance

“…2,3 Resource recovery from the AGS process is promising, including energy, biopolymers and struvite. 4 AGS reactors are operated as sequencing batch reactors (SBRs) with simultaneous plug-flow upward anaerobic feeding and effluent withdrawal, followed by an aerobic mixed reaction phase and settling. 5 Today, more than 80 AGS plants treating mainly municipal wastewater are operated around the world under the tradename Nereda®.…”

Aerobic Granular Sludge: Perspectives for Excess Sludge Management and Resource Recovery

“…The stored P is released from granules during the digestion process, which increases the efficiency of P capturing and recovery. Even though, Kehrein et al 76 found that the recovery rate of struvite‐P from ash incineration was 8‐times higher than the recovery rate from digestate supernatant. Liu et al 78 reported that the thermal pretreatment is effective for slow release of P from AGS.…”

“…[100][101][102] EPS can be used as bio-absorbent for dye and color removal from wastewater discharged from textile industries. [5,76,[93][94][95][96] EPS-Ps is also an attractive bio-sorbent for eliminating and recovery toxic metals.

Sustentabilidade No Uso De Fósforo: Uma Revisão Bibliográfica Com Foco Na Situação Atual Do Estado De São Paulo, Brasil

“…74,120 A estruvita (NH 4 MgPO 4 ) é um produto dos processos de precipitação química, com excelentes perspectivas de uso, já que tem grande relevância enquanto fertilizante, por ter em sua composição, além do fósforo, o nitrogênio e o magnésio. 63,74,121 A remoção de nutrientes e sua precipitação na forma de estruvita em baixas concentrações é um dos grandes desafios que a ciência busca resolver. 119,122,123 Além disso, a investigação dos efeitos desses materiais na fertilidade do solo e no desenvolvimento das plantas ainda é pouco conhecida.…”
