Fabrication of ceramic membranes from nano–rosette structure high alumina roller kiln waste powder for desalination application

Preparation and characterization of ceramic nanofiltration membrane prepared from hazardous industrial waste

“…The support ceramic membrane used throughout this study was mainly that prepared from kiln rollers hazardous, nonplastic fine waste, 12,13,27 which was kindly supplied by Ceramica Prima Company, (Sadat Industrial City, 70 km North of Cairo). It was characterized using X-ray fluorescence (XRF) by an Axios, P analytical 2005, and wavelength dispersive (WD-XRF) sequential spectrometer for chemical composition.…”

“…Filtration was performed on the laboratory filtration unit as shown in Figure 2. 12,13 Filtration setup consists of a stainless steel plate module of 50 mm in diameter; it has three openings for feeding, concentrate, and permeates. A closed feeding tank (5 L) was used for feeding using pressure pump.…”

“…The analyzed hazardous fine waste powder shows a chemical composition that is in good agreement with its XRD analysis. 12,13,27 Table 2 indicates that the Alumina and silica is the main components in the powder waste. Also, an almost zero loss on ignition was observed.…”

“…The results of TGA expect in view of the inert nature of its constituents (quartz + mullite). 12,13,27 3.2 | Application to water filtration…”

“…8,24,25 In that respect, Ahmed 23 found that the use of this powder depends on the firing temperature as it was used as shaped refractories on firing at 1300°C for 6 hours and as porcelain tiles on firing at 1350°C for 2 hours. Recently, Amin et al 12 and Abdallah et al 13 have succeeded in using this waste to produce nano-sized ceramic membrane for water desalination.…”
