The treatment of textile dyeing waste water
before disposal into the environment is
important and ensures safety to the environment
without affecting the quality of lakes, rivers etc.
Use of an economic method also plays an
important role. Thus natural product moringo
olifera powder seems to be more promising in
the treatment of coloured waste water. The
efficiency of treating the dye waste water using
Moringo olifera was also found to be more
effective. The colour removal percentage is
more than about 99%. Operating parameters
such as the coagulant dosage, reaction time, pH
and the initial dye concentarion has major role
on the efficiency of removal.
