What are Nanoscale Filters?
Nanoscale filters are advanced filtration systems that utilize
nanotechnology to remove particles and contaminants at the nanometer scale. These filters are engineered to have pores and structures that allow the selective passage of certain molecules while blocking others, making them highly efficient for various filtration applications.
How Do Nanoscale Filters Work?
Nanoscale filters operate based on physical and chemical principles. The small pore sizes, typically less than 100 nanometers, enable them to trap nanoparticles, bacteria, viruses, and other contaminants. These filters leverage properties such as
surface charge, hydrophobicity, and molecular size exclusion to achieve high levels of filtration efficiency.
