Efficient and eco-friendly adsorption using low-cost natural sorbents in waste water treatment

The removal efficiency of BOD 5 , COD and turbidity from wastewater using different sorbents to study their adsorption capacity has been studied. An eco-friendly technology in the wastewater treatment field with low cost has been promoted. Experiments have been performed by varying the operating parameters such as adsorbates, p H ranges and mixing contact time, the results obtained prove that the p H is very important in the retention process and removal efficiency wherein there is a broad variation among the p H ranges and that a good correlation coefficient R 2 = 0.99 show reliability of pseudo second order in the adsorption kinetics of different parameters onto the different sorbents.
