Application and treatment of dye congo red, metal and cod retention by modified membranes texture

Abstract

In materials research, the development of ceramic products is extremely interesting in the field of the membrane supports because of their mechanical resistance, chemical inertia, long working life and thermal stability. Research is currently directed towards the exploitation of materials at a lower cost. The application of ceramic membrane was believed can be utilized not only for medical and oxygen separation but also for various industry such as food and beverages industry, textile industry, metal industry and environmental. The purpose of this work is the development of modified ceramic support based on kaolin for liquid waste processing. The study of the water flow and filtration through the supports made possible to highlight a variation of retention rate varying from 99 to 100% in function of composition, pore diameter, ion interaction and molecular weight. Tests of filtration of Congo red solutions, salts solution, lead solutions and industrial waste water were performed on modified support which was synthesized starting from a natural local barb tine. Mixed with aluminium oxide. Using Filtration of tangential type under an applied pressure of 5 bar.
