Tannaries
Tannery wastewater arises from soaking, liming, tanning, and finishing operations and contains chromium, sulfides, salts, acids, lime, organics, and suspended solids.
These effluents have:
Hazardous waste like hexavalent chromium, sulfides, salts, lime, acids & organic residues.
Very high dissolved solids.
Elevated chemical oxygen demand (COD) & biological oxygen demand (BOD) levels.
Large volume of suspended solids.
Scaling & fouling issue.
Odor & gas formation.
SED’s MVR-based LTE® technology significantly reduces waste volumes, enabling a cost-effective and sustainable Zero Liquid Discharge (ZLD) solution.

Key Benefits
Engineered to handle diverse wastewater streams and flow capacities - direct effluent, effluent treatment plant reject, and RO reject with ease.
Recovers reusable salts, fat, protein, oil and other by-products, converting waste into value.
Maximize recovery while minimizing sludge generation, enabling safe and cost-effective disposal.
No extensive pretreatment or chemical dosing, resulting in lower operating costs and simplified operation.
Up to 99% reusable water recovery to reuse in process, cuts freshwater intake.
Low-temperature evaporation significantly reduces scaling and fouling, minimizing cleaning in place (CIP) frequency, ensuring higher uptime and lower maintenance costs.
