Carbon Coated Alumina Nanofiber Membranes for Selective Ion Transport

et al. 2017

The authors propose a novel type of ion-selective membranes, which combine the advantages of ceramic nanofibrous media with good electrical conductivity. The membranes are produced from Nafen alumina nanofibers (diameter around 10 nm) by filtration of nanofiber suspension through a porous support followed by drying and sintering. Electrical conductivity is achieved by depositing a thin carbon layer on the nanofibers by chemical vapor deposition (CVD). Raman and FTIR spectroscopy, X-ray fluorescence analysis, and TEM are used to confirm the carbon structure formation. The deposition of carbon leads to decreasing porosity (from 75 to 62%) and specific surface area (from 146 to 107 m 2 g À1 ) of membranes, while the pore size distribution maximum shifts from 28 to 16 nm. Measurements of membrane potential in an electrochemical cell show that the carbon coated membranes acquire high ionic selectivity (transference numbers 0.94 for anion and 0.06 for cation in aqueous KCl). Fitting the membrane potential data by the Teorell-Meyer-Sievers model shows that the fixed membrane charge increases proportionally with increasing electrolyte concentration. The carbon coated membranes are ideally polarizable for applied voltages from À0.5 to þ0.8 V. The potential applications of produced membranes include nano-and ultrafiltration, separation of charged species, and switchable ion-transport selectivity.

“…As mentioned before, a specific problem associated with the filtration of food processing wastewater is the accumulation of unwanted compounds on the membrane surface that if improperly washed may become a source of harmful bacteria [184]. The application of ceramic membrane technology can guarantee food hygiene due to its ease of cleaning and sterilization [185]. Moreover, ceramic membranes were successfully applied for milk and other dairy productions fractionation.…”

This paper presents a review of the previous laboratory analysis and case studies on the application of the pressure-driven ceramic membrane technology for treatment of industrial wastewaters. Ceramic membranes has attracted remarkable interests in recent decades for industrial wastewater treatment because of their superior characteristic such as high fluxes , reliable working lifetime under aggressive operating conditions and ease of cleaning. The literature review revealed that the efficiency of this technology has been proven in a wide variety of wastewaters from different industries and activities including pulp and paper, textile, pharmaceutical, petrochemical, food and mining. However, there are still challenges and questions for this technology that need to be addressed in future researches such as investment cost optimisation by introducing new fabrication technologies, selectivity, permeability and packing densities improvement, fouling minimisation and proposing scale up based on experimental research results.

“…The concept of liquid filtration was developed by Carre in 1960, and the filtration was done on dynamic zirconium hydroxide. In addition, SFEC is the first company to manufacture cross-flow filtration system equipped with the inorganic membrane (1978s) [18]. Recently, CMs have undergone notable development due to its different advantages and have been widely adopted.…”

“…The demand for products with higher nutritional value and of processing procedures less harmful to the environment and to human health has recently known a tremendous growth. Furthermore, transferring of membrane processing to food industries has been the objective of many studies [18,66]. The choice of working with CMs technologies in the food industry is mainly based on the different advantages obtained by these techniques such as ease of cleaning, food safety [67,68], and the acquisition of newly food fractions that can be used for other food process.…”

Desalination and Water Treatment

In recent years, there has been a growing interest in utilizing inorganic membranes, particularly alumina (Al 2 O 3) ceramic membranes (CMs), and to address a variety of separation problems in miscellaneous industry. Al 2 O 3 membranes are commercially predominant in CMs market. Al 2 O 3 material is generally used either as membrane support and/or as membrane layer due to advantages provided by this material and its derivatives such as availability in tonnage quantities, chemical inertness, good hardness, and thermal stability of the porous texture during elaboration steps. In this chapter, we comprehensibly look at the recent studies related to desalination and water treatment by ultrafiltration (UF), nanofiltration (NF) Al 2 O 3 membrane, and highlight the separation properties of the membrane in specific environmental pollution. The influences of membrane operating conditions and water quality on the rejection of pollutant by Al 2 O 3 membrane are reported through a series of bench-level experiments.
