Application of Fin System on Adsorption of Methylene Blue Dye using Adsorbent Coating Layer: Mathematical Formulae
Journal Title: Journal of Engineering and Technological Sciences - Year 2017, Vol 49, Issue 3
Abstract
Dye solution treatment using a fin system is a new adsorption treatment technique that can replace expensive conventional adsorption treatment units that are currently mostly used in industry. The fins function as the media for an adsorbent coating and are immersed in a tank containing dye wastewater. By installing the coated fins in the tank, the dye concentration can be easily reduced up to 90%. The purpose of the present study was to develop simple mathematical equations for the fin system using an adsorbent coating layer (ACL). The equilibrium adsorption data fitted to the Langmuir isotherm, indicating that the adsorption surface is homogeneous and in monolayer state. A mathematical formula derived from the isotherm model of adsorption was developed that can be used on large-scale removal of methylene blue dye from industrial wastewater since the error percentage between the calculated and the experimental values was less than 15%.
