About the brand
• This case study pertains to a leading international supplier of
active pharmaceutical ingredients (APIs).
• The company’s history in the generic API industry dates
back over 75 years.
• It employs more than 5,000 professionals at over 20 sites
worldwide
• It manufactures the industry’s broadest portfolio of over 300
API products.

Challenges
• One of the world’s largest and most diverse providers of
technical professional and construction services, were
consultants to the project.
• Treatability of the complex wastewater that was expected to
be generated out of this new unit was a challenge.
• The energy cost involved in treating the wastewater was a
prime concern.

5. 5
A.T.E.’s approach
• To address the treatment complexity and energy
requirements, an anaerobic and aerobic combination was
selected after a series of discussions with the customer and
the consultant.
• This is considered a first-of-its-kind solution for
pharmaceutical wastewater treatment.

Result
• The unique solution resulted in over 40% consistent COD
reduction in the anaerobic stage.
• Biodegradability of the wastewater also improved with anaerobic
treatment.
• There was a substantial reduction in the power consumption of the
aerobic stage.
• An overall COD reduction of 93% from feed COD of 13000 ppm
was achieved.
