SYNTHESIS OF BACTERICIDAL MICROFILTRATION CERAMIC MEMBRANES: Received: 01st September 2021; Revised: 25th November 2021, 11th December 2021, 29th January 2022; Accepted: 05th February 2022
Membrane technologies have become widely used in filtration and separation processes in chemical, oil, food, pharmaceutical, medical, environmental, textile industries, etc. Recently, there is a growing demand for the use of bactericidal membranes due to their effectiveness in neutralizing microorganisms. The aim of this work is to synthesize microfiltration ceramic membranes modified with silver nanoparticles to provide them with bactericidal properties. In this work, ceramic membranes are synthesized by dry pressing followed by sintering from natural raw materials of Ukrainian origin, namely: kaolin and saponite, as well as with the addition of silicon carbide, sodium silicate, and calcium carbonate. To provide ceramic membranes with bactericidal properties, they were modified with particles of silver. The synthesized ceramic membranes were characterized by X-ray diffraction and fluorescence analysis, and their bactericidal ability has been established. The ceramic filtration membranes after modification by silvers exhibited an inhibitory effect on the growth of Gram-positive (B. subtilis.) and Gram-negative (Escherichia coli) pathogens. Thus, the obtained bactericidal ceramic membranes are of great interest for their use for biofouling control

The structure, composition and geometric configuration of ceramic membranes were analyzed. A comparison with polymer membranes was made, as a result of which it was determined that the use of ceramic membranes is safer for the environment and will contribute to the creation of sustainable water treatment technologies, which can be completely closed. Despite their widely recognized shortcomings β fragility and cost, the use of ceramic membranes can pay off quickly due to higher performance and longer service life. Besides, a promising direction in overcoming these shortcomings is the fabrication of cheap and highly functional ceramic membranes using nanotechnology, modification of their surface against biofouling and for disinfection and creation of hybrid membranes. Additionally, the perspective direction of ceramic membranes creation based on low-cost raw materials and the development of cheap anisotropic inorganic membranes is outlined. In general, it is noted that membrane technologies, while eliminating certain shortcomings, will be recognized as a universal and "green" method of wastewater treatment, which will address a wide range of water treatment issues
