“…These results indicate that P removal by BPR–Fe and BPR–Fe–Si was not the simple sum of BPR and chemical methods but there may be an interaction between them. It has been proved that the P removal process of 522‐1 was growth‐dependent to some extent in our earlier study . Therefore, P removal may have some relationship with microbial assimilation.…”

“…Screening and cultivation methods of 522-1 have been described in a previous study. 15 Lysogeny broth (LB) medium for strain activation was prepared by dissolving 10.0 g L −1 peptone and 3.0 g L −1 yeast extract in 1000 mL seawater with salinity of 3.5%. The strain was activated in LB for 24 h first as inoculum.…”

“…It has been proved that the P removal process of 522-1 was growth-dependent to some extent in our earlier study. 15 Therefore, P removal may have some relationship with microbial assimilation. Recent studies also showed that the extracellular polymeric substances (EPS) of bacterial cells also played an important role in P reservation because there were a lot of charged functional groups and enzymes in it that could adsorb P or decompose polyphosphate, respectively.…”

BACKGROUND Seeking efficient phosphorus (P) removal methods is of great significance in both aspects of environmental protection and resource conservation. Silicon (Si) is always present in marine sediments and it contributes significantly to P removal by iron (Fe(III)) oxides. Marine microbes play the major role in marine biomineralization. The aim of this study was to investigate P removal performance by marine bacterium enhanced with Fe (III) in the presence of Si and the role Si played in the system. RESULTS The optimal Fe/Si/P molar ratio for P removal was 1:1.5:1. P removal efficiency was 47.79%, 96.02%, and 97.87% in systems of pure bacterial cultures, bacteria with Fe (III), and bacteria with Fe (III) and Si, respectively, at P of 30 mg L−1. Flocs and micro‐precipitates were formed around cells in P removal systems containing Fe (III) or Si. Moreover, the amount and size of flocs in systems containing Si were larger than those without Si. CONCLUSION P removal by marine bacterium enhanced with Fe (III) had good performance through precipitation and adsorption. Si was able to strengthen P removal ability and sludge settleability. This study can provide us with new insights into bacterial induced metal phosphate precipitate and into the marine P cycle. © 2017 Society of Chemical Industry

“…The large amount production of iron-and steelmaking slag has proposed a great challenge to the environment as it has been considered as pollutant. In fact, the slag has showed impressive performance on removing contaminants from air, water, and soil (Barca et al 2014(Barca et al , 2018Jo et al 2015;Yu et al 2015;Zhou et al 2016;Zuo et al 2015). It indicates that the iron-and steelmaking slag has great potential in the application of environment treatment practice.…”

Along with iron and steel production, large amount of slag is generated. Proper management on the iron-and steelmaking slag is highly demanded due to the high cost of direct disposal of the slag to landfill, which is the most adopted management approach. In this article, the potential application of iron-and steelmaking slag has been reviewed, which included the slag utilization in construction as cement and sand, in water, soil, and gas treatment, as well as in value material recovery. In addition, the challenge and required effort to be made in iron-and steelmaking slag management have been discussed.
