Abstract:

        Waste water generated from bulk drug manufacturing unit depicts high chemical oxygen demand (COD) of 34800 mg/l and biochemical oxygen demand (BOD) of 16,000 mg/l which was treated by vermifilters. Bulk drug wastewater was treated at different organic and hydraulic loadings using endemic species of earthworm Eudrilus eugeniae. Treated effluents were colourless and odourless at all the organic loadings with 2 days hydraulic loading. COD and BOD removals were in the range of 83.44% - 92.32% and 85.73% -93.92% respectively at two days hydraulic retention time (HRT). Marginal increase in COD and BOD removal were observed at 4 days HRT, but in terms of cost, it is not worth doubling the HRT. Vermicast showed good nutrient value. Treated effluent depicted sodium adsorption ratio (SAR) in the range of 3.95 and 4.76, which is well within the stipulated standard and is very congenial for land application. This paper discusses the feasibility of vermifilters in treating bulk drug waste waters.
