| Abstract: | This study presents the biodegradation of real textile
effluent pretreated with different hybrid methods. The experiments were carried
out with and without pretreatment of effluent to analyze the influence of
different pretreatment methods. The advanced oxidation processes such as
sonolysis, sono-sorption and sono-Fenton-sorption were employed for the
pretreatment of the effluent. In sono-sorption and sono-Fenton-sorption, eco-friendly,
cost effective and easily available tea waste was used as an adsorbent. The
sorbent was activated using formaldehyde followed by sonolysis. The
biodegradation was carried out using mixed culture and the optimal initial pH
and incubation temperature were found to be 7 and 32 oC,
respectively. The UV-vis and FTIR analyses of untreated and treated effluents
confirmed the degradation of organic pollutants. The microbial growth data
obtained were tested with Monod, Powell, Haldane, Luong and Edward equations
and the obtained data were found to fit well with Haldane model. |
