Challenges

Tannery wastewater challenges

Key effluent and compliance pressures WTT systems are designed to address.

Highly Variable Pollutant Mix
Cr³⁺, sulfides, proteins, fats, dyes, lime, salinity, high COD/BOD and strong odour create complex treatment challenges.
Tight Discharge Norms
Inland caps of COD ≤ 250 mg L⁻¹, BOD₅ ≤ 30 mg L⁻¹, Cr ≤ 2 mg L⁻¹, sulfide ≈ 0 mg L⁻¹, TDS ≤ 2,000 mg L⁻¹.
Occupational Hazards
Explosive H₂S evolves when alkaline beam-house liquors contact acidic chrome streams; rapid corrosion of metal and concrete.
Chrome-laden Sludge
Must pass TCLP or incur hazardous-waste levies, requiring specialized handling and disposal protocols.
Circular-economy Demands
Global brands audit water, salt and chrome loops (LWG, ZDHC, EU BREF) for sustainable operations.
