“…Some researches on waste from foundry industry have focused on DFSs due to their high volume (86% of generated waste [5]) and also to the various applications, such as utilization as aggregate in the manufacture of Portland cement concrete [6], and road paving [7,8]. Some works report the use of foundry waste, either without separation or mixed with other residues [9][10][11][12][13][14]. The number of published papers on the use of DFS in cement and concrete artifacts is extensive; however, few studies have focused on the use of DFS in the production of glass or glass-ceramic materials [2].…”

Recycling has been pointed out as an alternative to the disposal of waste materials in industrial landfills. In the present study, the transformation of residues (discarded foundry sand - DFS, grits, and lime mud) in glass-ceramic materials is shown. The glasses were obtained by the melting/cooling method. The precursor materials, glasses, and glass-ceramics were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), and differential scanning calorimetry/thermal gravimetric analysis (DSC/TGA). The glassy materials were milled, pelleted, and thermally treated at the crystallization temperatures given by DSC data to obtain the glass-ceramics (885, 961, and 1090 ºC). The main formed phases were cristobalite, α-wollastonite (parawollastonite), and β-wollastonite (pseudowollastonite). The glass-ceramics showed very low water absorption and apparent porosity (0.26 to 0.88 wt% and 0.66 to 1.77 vol%, respectively). The results confirmed that the studied residues can be used as raw materials for the manufacture of vitreous and glass-ceramic materials.

“…However, drinking water treatment residuals disposal remains one of the most urgent issues today. Several studies have given significant importance to the use of these waste materials in several different applications such as cement production (Dahhou, Barbach, & Moussaouiti, 2019; Dahhou, Moussaouiti, Arshad, Moustahsine, & Assafi, 2017; Rodríguez et al, 2010), ceramics production (Benlalla, Elmoussaouiti, Dahhou, & Assafi, 2015; Mymrin et al, 2017), application in agriculture (Fan, He, Ma, Yang, & Stoffella, 2014), and reuse as a coagulant (Ahmad, Ahmad, Ahad, & Alam, 2016; Sadri Moghaddam, Alavi Moghaddam, & Arami, 2010), adsorbent of organic pollutants (Fragoso & Duarte, 2012; Nawar et al, 2015; Rashed, El‐Daim El Taher, & Fadlalla, 2016), or heavy metal (Abo‐El‐Enein, Shebl, & Abo El‐Dahab, 2017; Cardoso et al, 2019; Siswoyo et al, 2019) in wastewater treatment.…”

Four different catalysts from drinking water treatment residuals (DWTR) were prepared via impregnation in the iron nitrate, calcined at different temperatures ranged from 200°C to 500°C, and tested for the reactive blue 19 oxidation using the heterogeneous photo-Fenton, under UVA light source. XRD and XPS results revealed that iron nature was found under a ferric oxide form (Fe 3+ ) similar to the magnetite. Calcination temperature results showed a significant effect on the activity of the catalysts. RB19 and TOC removals were 99% and 79%, respectively, with the best catalyst that calcined at 500°C in optimal conditions as follows: initial pH solution = 3, 10 mM of H 2 O 2 dosage, 0.5 g/L of catalyst loading, reaction temperature 35°C, and I UVA = 3.55 MW/cm 2 for 50 mg/L of RB19. The reusability of the catalyst after three cycles showed complete removal of RB19 and 65% TOC removal. © 2021 Water Environment Federation • Practitioner points• Synthetized heterogeneous photo-Fenton catalyst from drinking water treatment residuals for the photo Fenton oxidation. • The calcination temperatures plays a crucial role in catalyst photocatalytic activity.• Degradation of reactive blue 19 with Fe/DWTR-500 in presence of H 2 O 2 .• The Fe/DWTR-500 catalyst exhibited the best photocatalytic activity.• Reusability studies of Fe/DWTR-500 and the kinetics of reactive blue 19 degradation were investigated.

The photo-Fenton oxidation process was employed to degrade methylene blue (MB) using a hydroxide sludge/hydrochar-Fe composite as a catalyst prepared by physical activation of raw hydroxide sludge from a drinking water treatment plant and hydrochar-Fe prepared by hydrothermal carbonization from two-phase olive mill waste. The prepared composite was characterized by XRD, SEM, EDS, ICP, and FT-IR. The effect of major parameters, including pH, H2O2 concentration, and a dose of composite on the removal of MB has been studied. The results indicated that the MB decolorization rate increased with the increase of H2O2 concentration and catalyst addition; however, further increase in H2O2 concentration and catalyst dosage could not result in an increase of MB removal efficiency. A high degradation of 95% was achieved within 150 min under UV light irradiation at natural pH (pH = 5), a catalyst loading of 2.5 g/L, a H2O2 dosage of 14.68 mol/L, and MB concentration of 50 mg/L. Recycling studies show a MB decolorization of 92% after three cycles and the use of the composite for the degradation of another dye (methyl orange) shows a degradation of 99%, demonstrating that this composite is a promising heterogeneous photo-Fenton catalyst for long-term removal of dyes from industrial wastewater.
