Mathematical Model Describes Treatment of Waste Water Using Modified Activated Carbon

Extraction and preconcentration of Pb(II) from water and soil samples using modified activated carbon

In this work, a new extractant was prepared by immobilizing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, (5-Br-PADAP), on the activated carbon and applied to extraction of Pb(II) prior to determination by flame atomic absorption spectrometry. It was confirmed by FT- IR analysis. The metal ion was retained on the 0.05 g of the sorbent in the pH range 6-8, and then eluted with 5 mL of 0....

Chemistry of Pyrolysis and Kinetic Studies of Shea Nut (Vitellaria paradoxa) Shells Activated Carbon for Textile Waste Water Treatment

Phosphoric acid (H3PO4) and Zinc chloride (ZnCl2) catalyzed shea nut shells, subjected to a one way activation scheme was employed to study the adsorption kinetics and mode of diffusion of industrial dye uptake. Thermodynamics data obtained in this study indicate that the sorption of dye spontaneously increases with time and decreases after equilibration was...

Waste Water Treatment using MBR

A mathematical multi-objective model for treatment network design (physical-biological-thermal) using modified NSGA II

Today, sustainable development is one of the important issues in regard to the economy of a country. This issue magnifies the necessity for increased scrutiny towards issues such as environmental considerations and product recovery in closed-loop supply chains (CLSCs). The most important motivational factors influencing research on these topics can be considered in two general groups: environme...

Treatment of municipal waste water with special reference to activated carbon combined with sand

Waste water was collected from the municipal town of Madurai and was subjected to filtration in two different filters. The first filter employed sand for the process of filtration where as the second filter carbon for the same. Finally when the clarified water is drawn out of the filter, it shows that there is a considerable reduction in the physico-chemical parameters then that of the untreate...
