Hexavalent Chromium Wastewater Treatment Process: 2026 Specs and Costs
Chemical precipitation removes chromium by reducing Cr(VI) to Cr(III) at pH below 3.0 with 1.5–3× stoichiometric reductant and 30–60 minute holds, then precipitating Cr(OH)₃ at pH 8.5–9.5. Under 40 CFR 433.15, US metal-finishing pretreatment standards list total chromium at 2.77 mg/L daily maximum and 1.71 mg/L monthly average. Sludge is hazardous (EPA D007, 5.0 mg/L TCLP level), and hybrid IX or RO polishing supports permits below about 0.1 mg/L total Cr.
Chemical Precipitation for Nickel Removal: Specs and Cost Models

This guide covers reagent ratios, sludge TCLP paths, and CAPEX/OPEX ranges for 10 m³/h systems treating electroplating, battery, and semiconductor wastewater.
Chemical Precipitation for Copper Removal: Specs & Cost Models
Chemical precipitation removes copper from industrial wastewater with lime, sodium sulfide, or soda ash under controlled pH. At 100 mg/L influent copper, sulfide can reach 99.99% removal while lime typically reaches 98–99% with higher sludge volume. CapEx and OPEX scale with flow; a 50 m³/h lime train is about $275,000 CapEx and $135,000/year OPEX at 50 mg/L Cu.
Chemical Precipitation for Fluoride Removal: Specs and Costs
Chemical precipitation removes industrial fluoride by forming CaF₂ at Ca²⁺:F⁻ molar ratios of 1.2–1.5:1 and pH 8–9. Influent loads of 50–500 mg/L F⁻ are common in semiconductor and photovoltaic plants; precipitation handles bulk removal before DAF or RO polishing. Precipitation-only CAPEX for 50–200 m³/h is about $250,000–$800,000, with hybrid DAF-RO trains at $1.2–$3.5 million (2026). EPA 4 mg/L, China 10 mg/L, and EU 15 mg/L limits decide when polishing is required.
