THE ADDITION OF SOME COAGULANT AND VARIATION OF pH ON DEGRADATION OF TEXTILE WASTEWATER USING GAMMA RADIATION
ABSTRACT: The degradation and
decolouration of textile waste water by gamma irradiation has been studied.
Textile wastewater contain a mixture of dyes that difficult to degrade using
conventional method, therefore it is necessary to find another method to
degrade those dyes. Samples from effluent of textile industry were taken at
certain time and have different in colour and condition. The addition of
coagulant and radiation to remove the colour of the samples were demonstrated.
Four kind of treatments were carried out in this experiment namely addition of
coagulant, radiation, variation of pH and radiation, and combination of
radiation with the addition of coagulant. The parameters examined were the
change of spectra intensity, percentage of sedimentation after the addition of
coagulant, and the percentage of the degradation. Combination of irradiation
and the addition of coagulant induced decolouration and degradation of the
waste.
