Practitioner points
Basic Oxygen Furnace (BOF) Slag fines can be engineered as a cost‐effective alternative to conventional phosphorus and sulfur control strategies.
A rapid phosphate and sulfide removal from anaerobic digestates occurs within hours after BOF slag addition.
63% of phosphate and 78% of hydrogen sulfide were removed when digester sludge was dosed with 10 g BOF/L, without impacting digester performance.
Only a fraction of the dosed BOF slag contributed to digester TS, likely due to partial dissolution into the digestate.
BOF slag can potentially increase the nutrient content of biosolids, facilitate biogas recovery, and reduce odors.
The potential for steel slag fines from a basic oxygen furnace (BOF) to sequester dissolved phosphate and sulfide from anaerobic digester sludge was studied in mesophilic pilot‐scale digesters. A classic dose‐response behavior was observed with respect to phosphate and hydrogen sulfide sequestration.</description><identifier>ISSN: 1061-4303</identifier><identifier>EISSN: 1554-7531</identifier><identifier>DOI: 10.1002/wer.1208</identifier><identifier>PMID: 31433093</identifier><language>eng</language><publisher>United States: Blackwell Publishing Ltd</publisher><subject>Alkalinity ; Anaerobic digestion ; Anaerobic processes ; Anaerobic treatment ; Anaerobiosis ; Basic converters ; Biogas ; Biosolids ; Digesters ; Digestion ; Fermentation ; Fines ; Hydrogen sulfide ; Hydrogen sulphide ; Industrial Waste ; Mineral nutrients ; Nutrient content ; Nutrients ; Odors ; Oxygen ; Oxygen steel making ; Phosphates ; Phosphorus ; Recovery ; Refuse as fuel ; Resource management ; Resource recovery ; Sewage ; Slag ; Sludge ; Sludge digestion ; Solid waste management ; Sulfides ; Sulfur ; Sulphides ; Sulphur ; Wastewater ; wastewater treatment</subject><ispartof>Water environment research, 2020-03, Vol.92 (3), p.455-464</ispartof><rights>2019 Water Environment Federation</rights><rights>2019 Water Environment Federation.</rights><rights>2020 Water Environment Federation</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3868-3cbd61a0aec13eb01228e4b2cd1269af1d01ad34490787c921b4e0bb7f02c0d53</citedby><cites>FETCH-LOGICAL-c3868-3cbd61a0aec13eb01228e4b2cd1269af1d01ad34490787c921b4e0bb7f02c0d53</cites><orcidid>0000-0001-8598-1343</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1002%2Fwer.1208$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1002%2Fwer.1208$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,777,781,1412,27905,27906,45555,45556</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31433093$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Caicedo‐Ramirez, Alejandro</creatorcontrib><creatorcontrib>Laroco, Nicollette</creatorcontrib><creatorcontrib>Bilgin, Azize A.</creatorcontrib><creatorcontrib>Shiokari, Steven</creatorcontrib><creatorcontrib>Grubb, Dennis G.</creatorcontrib><creatorcontrib>Hernandez, Mark</creatorcontrib><title>Engineered addition of slag fines for the sequestration of phosphate and sulfide during mesophilic anaerobic digestion</title><title>Water environment research</title><addtitle>Water Environ Res</addtitle><description>The potential for weathered steel slag fines (D50 < 1.6 mm) to sequester dissolved phosphorus and sulfur from fermenting biosolids was determined.
