2) Treatment of Tannery Wastewater using Moringa oleifera
The effluent from tannery wastewater was treated with Moringa oleifera seed powder for the reduction of
Turbidity and COD. Variation in the COD at every 2,000 mg/l is carried out with optimum dosage 0.3gm/500ml of
Moringa oleifera and pH 4.5. The results obtained after the analysis are presented in Fig 3.5, 3.6, respectively, for
turbidity and COD.
