This study was carried out to check the effectiveness of Calotropis procera latex for bioremediation and to compare its efficacy with Moringa oleifera leaves extract. It was observed that considerable reduction in various physicochemical and bacteriological properties of the samples took place with Calotropis procera latex. After 1 hour of treatment itself, it carried out pH reduction of 11.11%, 30.00% and 12.50%, while Moringa oleifera leaves extract carried out 0.00%, 20.00% and 0.00% reduction and after 24 hours, turbidity was reduced to 90.00%, 61.87% and 65.36% with Calotropis procera latex and 75.00%, 60.43% and 32.03% with Moringa oleifera leaves extract for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively. Vanki river water showed a reduction in TSS and TDS of 2000 mg/L and 34000 mg/L with Calotropis procera latex and 3000 mg/L and 46000 mg/L, respectively with Moringa oleifera leaves extract. With Calotropis procera latex, the COD and BOD values were 544 mg/L, 608 mg/L and 800 mg/L; and 0.04 mg/L, 0.240 mg/L and 0.012 mg/L for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively. When treated with Moringa oleifera leaves extract, the COD values reduced to 864 mg/L, 800 mg/L and 896 mg/L and BOD values reduced to 0.004 mg/L, 0.251 mg/L and 0.022 mg/L, respectively. The total coliform count reduced to 130 MPN/100 ml, <1.8 MPN/100 ml and 7.8 MPN/100 ml for Vanki river water, Textile effluent and Paper & Pulp Industrial effluent, respectively after treatment with Calotropis procera latex. Thus, Calotropis procera showed better results in comparison with Moringa oleifera. So, it could be considered as the best alternative to prevent pollution.
