Composite ceramic membranes from natural aluminosilicates for microfiltration applications

Slaughterhouse wastewater characteristics, treatment, and management in the meat processing industry: A review on trends and advances

“…Physicochemical treatment involves the separation of the SWW into various components, typically the separation of solids from the liquor by sedimentation or coagulation/flocculation, and removal of pollutants using electrocoagulation (EC) and membrane technologies (Bull et al, 1982;Johns, 1995;San Jos e, 2004;Mittal, 2006;Eryuruk et al, 2014;Almandoz et al, 2015). Biological treatment are divided into anaerobic and aerobic systems as well as constructed wetlands (CWs).…”

“…Reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) processes are able to remove particles, colloids, and macromolecules depending on the pore size (Table 5). Membrane processes are also increasingly used for removal of bacteria, microorganisms, particulates, and organic matter in SWW treatment (Almandoz et al, 2015). Bohdziewicz and Sroka (2005) studied the performance of the RO process for SWW treatment as secondary effluent.…”

Synthesis of novel titania membrane support via combustion synthesis route and its application in decolorization of aqueous effluent using microfiltration

“…The typical preparation route for multilayer membrane starts with the production of goodquality support because effectiveness of such NF membranes greatly depends on the structural and mechanical properties of the membrane support (Alem et al 2009b;Dong et al 2010). Membranes with specific characteristic properties such as high flux, high porosity, pore size with narrow distribution, lower fouling rate, and stability are required for their applications in wastewater and effluent treatment processes (Almandoz et al 2015;Kumar et al 2015). For titania ceramic membranes, phase purity (anatase or rutile) or their composition is a unique characteristic for their applications in photocatalysis (Goei et al 2013).…”

Ceramic Filters and their Application for Cadmium Removal from Pulp Industry Effluent

“…Another study using local clays impregnated with silver compounds shows that clays that contain traces of crystalline albite or crystalline pyroxene have better sorption of silver species, and the mineralogy of the source materials was found to have the most significant influence on the strength of ceramic filters (Craver et al, 2014). The low-cost and locally produced tubular composite membranes from natural aluminosilicates (clay, bentonite, feldspar, quartz, alumina) were studied by Almandoz et al (2015). The results show that such composite membranes were suitable for microfiltration process and able to remove 100% insoluble residue and 87-99% of bacteria.…”
