Aggressive iron and manganese removal for West African borehole water. Delivers crystal-clear, odourless water from even the most challenging high-iron sources.
Iron contamination is the most common water quality issue in Ghanaian boreholes. Concentrations of 3–10 mg/L are typical in the Voltaian Basin, parts of Ashanti Region, and coastal aquifers. Dissolved iron (Fe²⁺) appears clear when pumped but oxidises on contact with air, producing reddish-brown staining, metallic taste, and bacterial fouling (iron bacteria).
Manganese (Mn) often co-occurs with iron, causing black staining and neurological health concerns at elevated concentrations. WHO limits: Fe < 0.3 mg/L, Mn < 0.1 mg/L. Most conventional filtration methods struggle with Ghana's high iron levels.
AquanOX is engineered specifically for aggressive iron/manganese removal in challenging African conditions. Its catalytic manganese dioxide surface oxidises dissolved iron and manganese rapidly, allowing filtration without chemical regeneration.
AquanOX operates as a catalytic oxidation filter. As water passes through the media bed, the manganese dioxide (MnO₂) coating catalyses the oxidation of ferrous iron (Fe²⁺) to ferric iron (Fe³⁺), and manganous manganese (Mn²⁺) to manganic manganese (Mn⁴⁺). The oxidised metals precipitate as insoluble hydroxides and are trapped in the filter bed.
During backwashing, precipitated iron and manganese are flushed to waste. The MnO₂ coating regenerates naturally in the presence of dissolved oxygen — no potassium permanganate or chemical dosing required for most applications.
Performance Range: AquanOX removes iron up to 15 mg/L and manganese up to 3 mg/L. For higher concentrations, contact our technical team for multi-stage system design.
