Stabilization of basic oxygen furnace slag by hot-stage carbonation treatment

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...

Enhanced phosphorus removal from wastewater by growing deep-sea bacterium combined with basic oxygen furnace slag.

As one solid waste with potential for phosphorus removal, application of slags in water treatment merits attention. But it was inhibited greatly by alkaline solution (pH>9.5) and cemented clogging generated. To give one solution, phosphorus removal was investigated by combining deep-sea bacterium Alteromonas 522-1 and basic oxygen furnace slag (BOFS). Results showed that by the combination, not...

Chromium stabilization of tannery sludge by co-treatment with ladle furnace slag

Hazardous solid wastes may pose a serious risk to human health and to the environment, if not managed appropriately and disposed of safely. In this study, the effective stabilization of tannery sludge, a toxic industrial solid waste produced from the physico-chemical treatment of tannery wastewaters, was examined by the addition of ladle furnace slag (LFS), another industrial solid waste. Moreo...

Evaluation of the Cooling and Pavement Performance of Basic Oxygen Furnace Slag Used in Asphalt Mixture

Basic oxygen furnace slag (BOF) is widely used in road construction, but there is a lack of characteristics in different asphalt mixtures. This study investigates the properties of hot-mixed asphalt (HMA), containing stone mastic asphalt (SMA), porous asphalt (PA), and dense-graded BOF as a partial substitution for natural aggregates. The purpose of this study is to evaluate various BOF slag co...
