SOURCES OF WASTE –
• Bharat Tannery Industry takes all the measures to limit the waste .
• It uses ecofriendly chemicals and before disposing to the rivers or nearby water
bodies it performs the screening operation and other treatments .
• The company operates with good pollution controls , doesn’t expose local
populations to health risk.
• But the processes of soaking, weaving, dying , liming , pickling , splitting ,
trimming leads to generation of waste water and some amount of solid wastes
like hide scraps , skin and excess fats
• Chromium contamination and high chemical oxygen demand are typical problems
associated with tannery effluents, both of which can pose serious risks to the
environment and human health.
RAJNI SHARMA , ENE -6TH SEM 6
• Toxins from this waste can leach into nearby soil and water, placing nearby residents
at risk of contamination.
• Through inhalation of dust or fumes, workers in tanning facilities can inhale airborne
chromium and this may risk their health.
• Main source of smells due to nitrogen and sulfur components use.
RAJNI SHARMA , ENE -6TH SEM 7
TREATMENTS OF WASTE GENERATED-
WASTE WATER TREATMENT:
• The company follows the following treatment process:
• Screening mixing settling aerated lagoons
• Other ways to reduce contaminants in water are :
• Using of trivalent chromium as it is far less toxic than chromium VI, water that
is contaminated with chromium VI can be treated with an electron donor that
converts the pollutant to its less damaging, trivalent state.
• Even bone charcoal, which is produced by burning animal bones, used as it has
the ability to remove chromium from water.
RAJNI SHARMA , ENE -6TH SEM 8
SOLID WASTE TREATMENT :
• To remove chromium contamination from soil vermiculture is practiced , which
involves the use of worms to concentrate heavy metals so that they can be
disposed away .
• Some forms of salt-tolerant bacteria used as they are able to decrease chromium
contamination in soil
TREATMENT OF HARMFUL GASES:
• By exhaust fans
• Cyclone separators
• Activated carbon
