Aim: The objective of
this study degradation of phenol, COD using anaerobic treatment by treating
coir retting wastewater and biogas production.
Methodology: Sludge from
sewage treatment plant was collected from Anna University, Chennai, India.
The retting pond wastewater was collected from Coir Industries, Kadayanallur.
A laboratory scale cylindrical shaped anaerobic reactor made of glass was
used in this study. The total volume of the reactor was 10 litre and the reactor
mainly consisted of a cylindrical column of 7 litre capacity (working
volume). The anaerobic reactor was fed with 6 litre of sludge and 1.5 litre
of coir retting wastewater. The gas produced in the reactor was measured
using a gas flow meter.
Results: The retting pond
wastewater was treated by lab scale anaerobic reactor. The anaerobic
treatment was carried out continuously for 15 days. Parameters such as pH,
TSS, TS, MLSS, COD and phenols were analyzed regularly during these
evaluations of the reactor performance. The concentration of phenol, TS, TSS
and COD decreased gradually with time removal percentage of 76%, 96%, 91% and
96% respectively. About 96% of total COD wastewater could be converted into
Interpretation: The results
indicate that anaerobic treatment has several advantages in the treatment of
retting pond wastewater and also in the production of biogas.
Key words: Anaerobic treatment, Coir retting, Wastewater
