dc.description.abstract |
ETP plays a pivotal role in functioning a textile industry and ensuring environmental safety
and sustainability. Various methods have been suggested over the years to enhance the effluent
quality and ETP capacity. This study focuses on improving the quality of the effluent by
applying Chemical Coagulant (PAC and Cationic Polymer) and Natural Coagulant (Moringa
oleifera). COD, Turbidity and Color was removed for different amount of dosages for both
coagulants, however, other parameters such as TSS, TDS, pH did not have a significant change.
The removal rate of PAC and Polymer combination for COD, Color and Turbidity was 34.89%,
22.35% and 42.53% respectively. On the other hand, Moringa oleifera had a removal rate of
12.77%, 21.83% and 18.6% for COD, Color and Turbidity respectively. Optimum dosages of
PAC and Polymer for COD removal was 2% and 1.6%, while for Moringa oleifera the optimum
dosage was 50 mg/L. For color and turbidity removal, the optimum dosages of PAC and
Polymer was 4% and 3.2%, while for Moringa oleifera it was 20 mg/L. The study shows that
the combination of PAC & Polymer had a better removal efficiency of Color, Turbidity and
COD, as compared to the performance of Moringa oleifera.
It also offers a redesigning approach to enhance the capacity of the treatment plant by 20% to
meet the criteria for future extension and compares the variation between existing design and
the calculated design. |
