Abstract This work presents the impact of fabricating pressure on the performance of ceramic membranes during the dead-end microfiltration of an oil-water emulsion. The membranes used in this study were fabricated at a pressure of 40 kN and 100 kN using the dry compaction method. The membrane characterization was done using XRD and FTIR analysis. The membrane performance was evaluated by carrying dead-end microfiltration experiments using synthetic oil-water emulsion as a feed at a trans-membrane pressure of 30 psi. The experimental results confirmed that the membrane fabricated at higher fabricating pressure (100 kN) gives better performance in terms of maximum oil rejection of 95.7% with the maximum flux of 2.04x10−3 m3/m2.s.

Porous Al2O3 membranes were prepared through a phase-inversion tape casting/sintering method. The alumina membranes were embedded with finger-like pores perpendicular to the membrane surface. Bare alumina membranes are naturally hydrophilic and underwater oleophobic, while fluoroalkylsilane (FAS)-grafted membranes are hydrophobic and oleophilic. The coupling of FAS molecules on alumina surfaces was confirmed by Thermogravimetric Analysis and X-ray Photoelectron Spectroscopy measurements. The hydrophobic membranes exhibited desired thermal stability and were super durable when exposed to air. Both membranes can be used for gravity-driven oil/water separation, which is highly cost-effective. The as-calculated separation efficiency (R) was above 99% for the FAS-grafted alumina membrane. Due to the excellent oil/water separation performance and good chemical stability, the porous ceramic membranes display potential for practical applications.

Oil Water

The wastewater produced by the metal industry is often present in the form of oil-in-water (O/W) or water-in- oil (W/O) emulsions. These fluids contain a certain amount of valuable oil that can be recovered in the recycling process. Therefore, the development of novel, efficient, and low cost processes for the treatment of metalworking fluid is necessary. Demulsification to separate oil/water mixtures is a very interesting option because it allows the recovery and reuse of the lubricant oil and effects in cleaner, easily treatablemwastewater.Chemical destabilization is the most common way of demulsification of metalworking fluids. As an example, inorganic salts can be used as demulsifiers. In the presented work the efficiency of treatment of cutting emulsions with chemical demulsification with usage of aluminum sulfate (IV) is described. The emulsion was prepared with Emulgol-ES12 self-emulsyfing oil delivered by Orlen S.A. In the research the feasibility of the demulsifier was checked.The novel in this paper is determination of the optimal dosage of emulsifier using the TurbiscanLab® apparatus. It is relatively quick and precise method that can be applied in the industry.

Optimum Balance

Support is a necessary foundation for ceramic membranes to achieve high performance. Finding the optimum balance between high performance and low cost is still a significant challenge in the fabrication of ceramic supports. In this study, low-cost fly ash-based ceramic supports with enhanced performance were prepared by the addition of bauxite. The pore structure, mechanical strength, and shrinkage of fly ash/bauxite supports could be tuned by optimizing the bauxite content and sintering temperature. When the sintering temperature and bauxite content were controlled at 1300 °C and 40 wt%, respectively, the obtained membrane supports exhibited a high pure water permeance of approximately 5.36 m3·m−2·h−1·bar−1 and a high bending strength of approximately 69.6 MPa. At the same time, the optimized ceramic supports presented a typical mullite phase and excellent resistance to acid and alkali. This work provides a potential route for the preparation of ceramic membrane supports with characteristics of low cost and high performance.
