Decontamination of metal-contaminated waste foundry sands using
The washing remediation of waste solids using chelants has been recommended to overcome the challenges related to acid-induced leaching of harmful elements [15], [16]. Chelant-assisted washing can transfer the PTEs from the solid phase to the aqueous solution at a significant rate due to the complexation reaction [16], [17].Collectively these results suggest a potential relationship between pathogens and FIB in sand. The subsequent sections begin by describing the presence of FIB in beach sands and then subsequently describe pathogenic fungi, parasites, and viruses that have been found in beach sands and that could pose potential risks to beachgoers. Routine screening of harmful microorganisms in beach sands

Crystals Free Full-Text Biocementation of Calcareous Beach Sand
Beach sands are composed of a variety of minerals including quartz and different carbonate minerals. Seawater in beach sand contains several ions such as sodium, magnesium, calcium, chloride, sulfate, and potassium. These variations in mineralogy and the presence of salts in beach sand may affect the treatment via enzyme-induced Optimal washing parameters for sand contamination levels in the range 0.5-20 g/kg were identified with response surface methodology. While HPB-CD and SR performed equally to TX only at low sand contaminations, SL-1 attained hydrocarbon removal higher or equal to that of TX at any IFO-180 contamination and at lower application rates.Optimization of washing conditions with biogenic mobilizing

Effects of treatment agents during acid washing and pH
Acid washing effectively reduced the total contents (Table A4) and mobility (Fig. 1) of heavy metals in the dredged marine sediment.The HCl was verified as the most effective acid solutions, followed by HNO 3 and H 2 SO 4.The same order of acid performance was observed with statistical significance (one-way ANOVA; p < 0.05) for all Sand from deserts, rivers, and seas is selected as the representative of natural sand. The initial purity of silica is 52.1 wt% for desert sand, 39.3 wt% for river sand, and 35.8 wt% for sea sand.
