Technological Advances in Ceramic Membranes for Water Treatment
Summary
This review examines technological innovations in ceramic membrane materials and fabrication for water treatment, covering Al2O3, TiO2, SiO2, and ZrO2-based membranes and their surface modifications. It finds ceramic membranes effective at removing heavy metals, pathogens, and other contaminants including microplastics, but notes that high acquisition, maintenance, and operating costs limit broader adoption.
A study on the technological innovations in the development of ceramic membranes for water treatment is provided. These membranes have proven to be effective in removing contaminants in the water, such as heavy metals and pathogens. It discusses the different materials based on oxides such as Al2O3, TiO2, SiO2, and ZrO2, used in manufacturing, as well as fabrication techniques and surface modifications that have improved their properties. In addition, the environmental and economic impact on water treatment plants is addressed. From a financial point of view, implementing membranes can be an investment, both in acquiring the membranes and in the infrastructure. Membrane maintenance and operating costs are often high, which can affect the economic viability of the treatment plant. The results suggest ceramic membranes are a viable and efficient option for treating polluted water.
