Chemical risks drive layout
Chromium-bearing streams and sulfide processes must stay segregated. Accidental mixing creates safety hazards and can collapse biological treatment performance across an entire CETP.
Chrome recovery or closed-loop tanning liquor recycle can materially cut loads. What remains still carries chlorides and organics that complicate direct reuse.
Pickling and preservation push TDS. RO may work on compatible fractions, but reject needs alloys, cleaning protocols, and solids handling matched to aggressive chemistry.
True ZLD requires explicit plans for salt cake, softening sludges, and landfill acceptance—especially when multiple tanneries feed one hub.
Phase upgrades: stabilize inlets, add instrumentation, then add concentrators. Concentration without segregation is a frequent source of failed pilots.
