Dynamics of Adsorption Isotherms for the treatment conductivity and hardness of effluent with Novel Isolated Microorganism

Microorganisms possess a capacity to accumulate organic and inorganic matter in their body, evoke the process of their enzymatic transformation and adsorb them on the cell surface. Detailed batch studies with the selected JRll microbial biomass as a adsorbent, has been carried out to investigate the effect of pH, contact time on the adsorption isotherm for Hardness and Conductivity. Isolated bacterial strains JRll posses the capacity to reduce Hardness and Conductivity of water about 80±2% at pH 7 with contact time of 85 minutes. The adsorption kinetic study satisfied the model Langergren and Frendulich equilibrium constant. Adsorption capacity was found to be 47.2 and 26 mg/g of adsorbent for Hardness and Conductivity respectively.
