In Bangladesh, the effluent from so many textile factories have a high
pH. In the treatment plants for this effluent, usually sulfuric acid
is used to adjust the pH. However, in Bangladesh, hydrochloric acid is
significantly cheaper than sulfuric acid.

I am working on a report to justify the substitution of the
conventional uses of chemicals with more economic ones.

I need some opinions from experts and some more issues to consider –
if any. Some related references to further study the matter would be
highly appreciated as well.
