The remediation effectiveness of a Fe°/Sand/Pozzolan (Fe°/S/Pz) ternary device using an azo-dye for characterization is demonstrated herein. Optimal operating conditions, which specify the proportions of solid materials, such as iron (Fe°), sand (S), and pozzolan (Pz), in the reactive zone (RZ), are essential factors for the performance of such heterogeneous devices. Thus, the operative indicator orange methyl (OM) of 2 mg/L was used. Performance parameters such as pH, released iron of the collected water, flow rate, and fading power were measured using filter devices containing (1) 100% Fe°, (2) 25%/75% Fe°/S, (3) 25%/75% Fe°/Pz, (4) 25%/0%/75% Fe°/S/Pz, (5) 25%/25%/50% Fe°/S/Pz and (6) 25%/50%/25% Fe°/S/Pz for a correlation of proportions, reactivity, and performance. The experiments lasted thirty (30) days per device. It turns out that ranges of 25% ≤ % Fe° ≤ 60%, 25% ≤ %S ≤ 50%, and 25% ≤ %Pz ≤ 50% are quite enough. The ternary device, in ratios of 25%/50%/25% Fe°/S/PZ, is an excellent decontaminant of orange methyl OM, with regulation of pH and residual iron levels, for acceptable flows. There are therefore beneficial effects of the association of a non-expansive porous material with Fe°-based filters to delay clogging by collecting corrosion products (CPs). 25%/50%/25% Fe°/S/PZ device allow to reduce greatly the proportion of iron in the reactive zone (RZ) since pure iron devices are not recommended due to clogging. 25% ≤ % Fe° ≤ 60%, 25% ≤ %S ≤ 50%, and 25% ≤ %Pz ≤ 50% could provide a necessary framework for all Fe°-bed filters.

abstract = {The remediation effectiveness of a Fe°/Sand/Pozzolan (Fe°/S/Pz) ternary device using an azo-dye for characterization is demonstrated herein. Optimal operating conditions, which specify the proportions of solid materials, such as iron (Fe°), sand (S), and pozzolan (Pz), in the reactive zone (RZ), are essential factors for the performance of such heterogeneous devices. Thus, the operative indicator orange methyl (OM) of 2 mg/L was used. Performance parameters such as pH, released iron of the collected water, flow rate, and fading power were measured using filter devices containing (1) 100% Fe°, (2) 25%/75% Fe°/S, (3) 25%/75% Fe°/Pz, (4) 25%/0%/75% Fe°/S/Pz, (5) 25%/25%/50% Fe°/S/Pz and (6) 25%/50%/25% Fe°/S/Pz for a correlation of proportions, reactivity, and performance. The experiments lasted thirty (30) days per device. It turns out that ranges of 25% ≤ % Fe° ≤ 60%, 25% ≤ %S ≤ 50%, and 25% ≤ %Pz ≤ 50% are quite enough. The ternary device, in ratios of 25%/50%/25% Fe°/S/PZ, is an excellent decontaminant of orange methyl OM, with regulation of pH and residual iron levels, for acceptable flows.

Optimal operating conditions, which specify the proportions of solid materials, such as iron (Fe°), sand (S), and pozzolan (Pz), in the reactive zone (RZ), are essential factors for the performance of such heterogeneous devices. Thus, the operative indicator orange methyl (OM) of 2 mg/L was used. Performance parameters such as pH, released iron of the collected water, flow rate, and fading power were measured using filter devices containing (1) 100% Fe°, (2) 25%/75% Fe°/S, (3) 25%/75% Fe°/Pz, (4) 25%/0%/75% Fe°/S/Pz, (5) 25%/25%/50% Fe°/S/Pz and (6) 25%/50%/25% Fe°/S/Pz for a correlation of proportions, reactivity, and performance. The experiments lasted thirty (30) days per device. It turns out that ranges of 25% ≤ % Fe° ≤ 60%, 25% ≤ %S ≤ 50%, and 25% ≤ %Pz ≤ 50% are quite enough. The ternary device, in ratios of 25%/50%/25% Fe°/S/PZ, is an excellent decontaminant of orange methyl OM, with regulation of pH and residual iron levels, for acceptable flows. There are therefore beneficial effects of the association of a non-expansive porous material with Fe°-based filters to delay clogging by collecting corrosion products (CPs). 25%/50%/25% Fe°/S/PZ device allow to reduce greatly the proportion of iron in the reactive zone (RZ) since pure iron devices are not recommended due to clogging. 25% ≤ % Fe° ≤ 60%, 25% ≤ %S ≤ 50%, and 25% ≤ %Pz ≤ 50% could provide a necessary framework for all Fe°-bed filters.
