Abstract

Ceramic filters prepared by recycling of industrial solid waste have drawn considerable research interests for various separation and purification applications. In search of low-cost and environmentally friendly utilization of solid waste, this study focuses on synthesis of porous alumina ceramic filters by partial sintering at 1200 °C using Al₂O₃, coal derived solid waste as sintering additive, and MoO₃ as catalyst. The effects of processing parameters on the materials properties of filters, water permeability, aerosol and wastewater filtration efficiency were investigated. The filters prepared using 20 wt% coal fly ash was found to be optimal and exhibited a flexural strength of 45.6 MPa at porosity of 40.8 vol%, and water permeability of 1084 LMH bar⁻¹ and also showed good performance in removal of oil and turbidity from oily wastewater. This work may appeal to the practical low-cost production of high-performance alumina ceramic filters with a wide range of potential applications.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
