Cleaner Technology: Tannery in India
Interventions
Water mixing and management
(Control of float level were
demonstrated using three
methods of measurement)
Hair save unhairing (A screw type
filter for recovering hair from the
liming-unhairing float)
Processing fresh chilled hides
Desalting of raw hides
Results
Reduced the water consumption
by 20 to 30%
Reduced COD 32%, BOD 37%,
Sulphide 66% and TSS 61%
TDS discharge in effluent is
reduced by between 30% and 40%
15% reduction in TDS in the
effluent stream due to desalting of
raw hides/skins
Remarks
Reduction of pollutants like COD
and TDS by 15% and 10% in the
dyeing/fatliquoring bath
contributed by increased uptake
of chemicals
Significantly lower volume of
sludge, improvements in the
waste water discharge due to
fewer chemicals used
Contributes to substantial
improvements in the waste water
discharge.
Will reduce effluent treatment
cost
