Abstract

The research carried out in this paper aimed to identify and compare the mechanical filtration capacity of the existing nanoparticles, correlated with the electro-chemical properties of the drinking water provided to the household users through the public network of Cluj-Napoca. The tested filters are available to the general public and the results of the research provide both the certainty of the importance of using drinking water filters, but also the prospect of purchasing an optimal relation quality - price filter based on the needs of the domestic users.

The qualitative analysis of the tested filters was carried out by laboratory testing of a representative sample of drinking water filters that once reached the maximum lifetime, were cut and subjected to microscopic analysis using an Atomic force microscope (AFM). The microscopic analysis aimed to determine the filtration capacity by identifying the size and agglomeration density of the nanoparticles retained by mechanical filtration.
