Basic Oxygen Furnace steel slag and apatite for sustainable phosphorus removal at small wastewater treatment plants
Recent developments in phosphorus (P) removal have focused on P reactive materials to use within constructed wetlands (CW), as a sustainable alternative to chemical dosing. In this study, different fractions of Basic Oxygen Furnace (BOF) steel slag and apatite media have been tested in full-scale CWs, being the first trial of its kind in the United Kingdom evaluating the P removal capacity of b...
متن کاملDual slag filters for enhanced phosphorus removal from domestic waste water: performance and mechanisms
The phosphorus (P) removal of five combinations of dual filters consisting of blast furnace slag (BFS), argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) was evaluated in column experiments with domestic waste water. The columns were fed with waste water for 24 days. The column with only EAF had the best P removal performance (above 93% throughout the experiment). The ...
متن کاملEAF Steel Slag Filters for Phosphorus Removal from Milk Parlor Effluent: The Effects of Solids Loading, Alternate Feeding Regimes and In-Series Design
Electric arc furnace (EAF) steel slag filters were investigated for their efficiency at reducing the concentration of phosphorus (P) from dairy farm wastewater in Vermont. The primary objective for this study was to examine the use of in series design on filters’ performance in P removal from dairy farm wastewater at subzero temperatures. Other research objectives were to investigate operationa...
متن کاملEffect of aging on Phosphorus removal of metallurgical slag and heat reactivation of aged slag
In order to examine the effect of ageing on P removal capacity, the phosphorus (P) removal capacity of three types of slag, argon oxygen decarburisation slag (AOD), blast furnace slag (BFS) and electric arc furnace slag (EAF), was examined after 0, 10, 13 and 19 months in batch experiments. The results showed that ageing reduced P removal capacity, e.g. by 78.4% for 19-month-old AOD slag. For B...
متن کاملLong-term evolution of highly alkaline steel slag drainage waters
The disposal of slag generated by the steel industry can have negative consequences upon the surrounding aquatic environment by the generation of high pH waters, leaching of potentially problematic trace metals, and rapid rates of calcite precipitation which smother benthic habitats. A 36-year dataset was collated from the long-term ambient monitoring of physicochemical parameters and elemental...
