3.Results and discussion
The focus on waste minimization and water conservation in recent years has resulted in the production
of concentrated or toxic residues. Due to the increasing presence of molecules, refractory to the
microorganisms in the wastewater streams, the conventional biological methods may not be used for
complete treatment of the effluent in some cases and hence, using chemical oxidation to degrade these
refractory molecules into smaller molecules, has become imperative. The produced small molecules can
be further oxidized by biological methods.
