Taking sponge iron as seed material, the effect of different reaction conditions on the recovery of phosphorus in waste activated sludge by vivianite crystallization was studied. Through single factor tests, the optimal conditions for vivianite formation were in the pH range of 5.5–6.0 with Fe/P molar ratio of 1.5.

Vivianite (Fe(II) 3 (PO 4 ) 2 * 8H 2 O) plays a crucial role in capturing the phosphate, and if enough iron is present in the sludge after anaerobic digestion, 70–90% of total phosphorus (P) can ...

DRI (Direct Reduced iron), commonly known as Sponge Iron, is a metallic product produced through the direct reduction of iron ore (in the form of lumps, pellets, or fines) in the solid state. It is a substitute for scrap and therefore is mostly applicable in making steel through the secondary route. Download Brochure.

Meanwhile, the total phosphorus (TP), OP, Fe/Al-P, and Ca-P content in sediment increased by 33.8, 7.7, 23.1, and 23.1 %, respectively, implying that under the action of sponge-iron, the locked ...

The research result showed that the phosphorus removal ratio of sponge iron/sulfur composite fillers was over 95%, which was increased by 30% as compared …

Degree of metallization = (weight of metallic iron/weight of total iron)* 100 = (Fe M/Fe T)*100. Equivalent metallization – Carbon content in sponge iron at a given degree of metallization is important. It has the capacity to remove oxygen from the remaining iron oxides during steel making.

The difference was that sponge iron and IHO was added as seed crystal instead of FeCl 3 after addition of substrate sludge and inoculated sludge. The concentrations of sponge iron and IHO were both 3 g/L. The Fe/P ratio was controlled at 1.5:1 and the initial pH value was 6. Chemical analysis. The pH was determined by a pH …

Phosphorus and sulfur are the main harmful elements in the sponge iron of which the phosphorus content should not be higher than 0.06%, and the sulfur content should not be higher than 0.03%. The main characteristics of sponge iron steelmaking are as follows: (1) The sponge iron is relatively pure so increasing the proportion of …

found that autotrophic denitrication and Fe3+-based phos-phorus immobilization were enhanced in iron carbon (Fe–C) layer. Moreover, it was proven that the microbial abundance related to denitrication process increased notably due to the addition of iron scraps and activated carbon (Shen et al. 2019).

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Sponge iron (s-Fe0) is a porous metal with the potential to be an electron donor for denitrification. This study aims to evaluate the feasibility of using s-Fe0 as the substrate of wetland mesocosms. Here, wetland mesocosms with the addition of s-Fe0 particles (CW-Fe) and a blank control group (CW-CK) were established. The NO3−-N …
