摘要: This study aims to investigate the ability of low cost ceramic membrane filtration in removing three common heavy metals namely; Pb 2+ , Cu and Cd from water media. The work includes manufacturing membranes with dimensions 15 by cm 2 thickness. were made materials local clay mixed different sawdust percentages 0.5%, 2.0%, 5.0%. used was characterized XRD X-ray fluorescence analysis. Aqueous solutions prepared laboratory filtered through membranes. influence main parameters such as pH, initial driving pressure head, concentration on their removal efficiency investigated. Water samples collected before after process metal concentrations determined chemical Moreover, a microstructural analysis using scanning electronic microscope (SEM) performed process. results showed high up 99% for concerned metals. SEM images approved these showing adsorbed ions sides internal pores
