Feasibility of wet-extraction of phosphorus from incinerated sewage sludge ash (ISSA) for phosphate fertilizer production: A critical review

Critical Reviews in Environmental Science and Technology, Journal Year: 2020, Volume and Issue: 51(9), P. 939 - 971

Published: April 6, 2020

Incinerated sewage sludge ash (ISSA) is produced worldwide where incineration used to manage sludge. ISSA contains significant amounts of phosphorus (P) with high recovery potential, and may contribute mitigate the global P supply problem. This study reviews transformation in incineration, characteristics resultant processes for from focusing on wet-extraction methods due their greater feasibility. The major drawback method co-dissolution metal(loid)s. Hence, purification P-extract necessary produce a fertilizer. Based analysis, three recommendations are made further studies. One optimizing extraction process content low contents impurities. second develop plant-available adsorption media, which can selectively adsorb acid-extract making P-laden media as fertilizers directly. third form high-purity product that would be cost-competitive attractive use diverse sectors. Finally, since criteria recovered phosphate fertilizer incomplete, agronomic effectiveness newly should evaluated prior large scale applications.

Overview of recent advances in phosphorus recovery for fertilizer production

Engineering in Life Sciences, Journal Year: 2018, Volume and Issue: 18(7), P. 434 - 439

Published: April 16, 2018

Abstract This Mini Review gives an overview of and respective references for the current situation regarding global phosphorus reserves legal P recovery using Germany as model. Apart from well‐known pilot up to industrial/full scale techniques, emerging chemical bio‐based techniques are named without claiming be all‐encompassing. Special attention is paid biological systems that reveal ways use renewable resources raw materials. A few chemically based like AirPrex®, (Ostara)PEARL™, AshDec®, RecoPhos® have already been used recover at a rate quality which allows its sale fertilizer. Many processes stage investigation on or laboratory scale, e.g. P‐RoC, LeachPhos, Mephrec®. All biologically technologies P‐Bac still early research show promising results. Of all recovered materials struvite, calcium phosphate bound phosphorous seem best plant availability. Although there no ultimate “one fits all” technology, potential P‐recovery operators can choose wide range will fit local material availability, economic ecological situation.

Fate of calcium, magnesium and inorganic carbon in electrochemical phosphorus recovery from domestic wastewater

Chemical Engineering Journal, Journal Year: 2019, Volume and Issue: 362, P. 453 - 459

Published: Jan. 11, 2019

Calcium (Ca), magnesium (Mg), phosphate and (bi)carbonate are removed simultaneously in electrochemical recovery of phosphorus (P) from sewage. However, the fate these ions is not completely understood yet. In this paper, through wastewater acidification current density altering, we clarified precipitation process interaction coexisting ions. The removal P attributed to amorphous calcium (ACP) formation, whereas bicarbonate mainly due calcite (CaCO3) formation acid-base neutralization. While both ACP results Ca removal, predominantly ends up calcite. For Mg, it exclusively as brucite (Mg(OH)2). Regardless acidification, 53 ± 2% 32 1% Mg were 24 h at 8.3 A/m2. By contrast, response dropped 42% 19%. depends on density, with less than 5% 1.4 A/m2 but 70% 27.8 h. Based mechanisms, can be reduced by operating a relatively low respectively. Accordingly, achieved lowest Ca/P molar ratio (1.8) highest relative abundance precipitates (75%) bulk pH 3.8
