The coatings are thin (<50 nm) and relatively uniform. These coatings enhance the performance of the hybrid ozonation-filtration process. With the coated membranes it is possible to significantly reduce fouling, improve the removal of DBP precursors and more effectively kill Escherichia coli bacteria.
