dc.description.abstractIn a typical wastewater treatment flow sheet used by several industrial units in India, various stages of treatment include primary treatment, followed by secondary treatment, and tertiary treatment. The concentration of total dissolved solids increases during neutralization of the wastewater with acid/ alkali during primary treatment, which adversely affects the activity of microorganisms during biological treatment. The present study aims at demonstrating that adsorption as the first stage of treatment shall increase efficiency of the subsequent biological treatment. Experiments were carried out on different wastewater samples from chemical plants on adsorbents viz. activated carbon, bentonite, and lignite. The effectiveness of adsorbents in the removal of refractory organics by way of reducing chemical oxygen demand and colour is evaluated. The results of COD reduction are fitted into different models available in literature including the new model Rathi Puranik equation, which requires least experimentation for predicting COD values.en_US
