Environmental Biotechnology

Upon completion of this

course, students will:

CO49: Develop the ability to

assimilate the concepts and

specific                 terminology            of

environmental biotechnology.

CO50: Design new tools and

techniques   in                    the                    fieldof

environmental biotechnology

for the betterment of the

environment                           and                           its components.

CO51: Defend the existing

physical       and                   chemical

processes involved in water

and waste water treatment

and modify them if possible.
