Abstract

Mongolia has few freshwater resources. It is therefore important to conserve water resources. An efficient possibility is to purify water and reuse it. Therefore, the scientists from the Material Science Center of the Mongolian University of Science and Technology collaborated with the researcher from the Korea Institute of Material Science and carried out a project between 2017-2020. In this study, Mongolian zeolites and prepared kaolin were used and flat tubular porous support was extruded by a double screw vacuum extruder at KIMS. The supports were burned at 800 and 1000°C and the properties such as pore distribution were determined by mercury porosimetry. The zeolite-kaolin support had a bulk density of 1.46 g/cm3, a porosity of 41.52% and, an average pore size of 218 nm. With its water permeability of 115 L/m2·h at 0.01 MPa and 970 L/m2·h at 0.08 MPa, the support achieved good results. The wastewater treatment tests show that these membranes also have good compressive strengths. We have cleaned the sewage from a leather factory, which was very highly contaminated and has high viscosity.
