Cr⁶⁺ Neutralization & Mine-Water Reuse

Water Type: Chromite mine runoff, pit water, and drainage

Performance Highlights (from calibration & third-party validation):

• Hexavalent Chromium (Cr⁶⁺) neutralization and removal
• Turbidity reduction
• Temporary Hardness
• Metals (Fe, Mn) reduction & removal
• Sludge: TCLP-compliant for safe handling/disposal; low generation rate
• Operations: low-energy footprint; treatment performance unaffected by trace oil/emulsions

Water Types Covered:

• River Water — Hilltop WTP intake
• Mine Water — Mines ZLD circuit
• ETP Water — Lagoon Pumping Station

Performance Highlights:

• Organic load (COD/BOD) and inorganics (incl. heavy metals, hardness) significantly reduced across all streams
• Mine Water & ETP Water treated to discharge-compliant quality
• River Water improved to drinking-water
• Treatment performance unaffected by oil/emulsified hydrocarbons or load variability
• Negligible sludge generation; low energy footprint → strong operating economics

Water Type: Textile process water (dyeing/finishing)

Performance Highlights:
