Changing of Contaminants Content and Disperse State during Treatment and Transportation of Drinking Water

Abstract:

Number concentration of colloidal particles and concentration of several drinking water contaminants (iron, aluminium, AOX) were determined in river water, water treated at WTP, tap water and their filtrates (pore diameter of filter 60 nm). It was shown that almost all AOX were present in highly disperse state (less than 60 nm), 55...90% of iron and 55...80% of aluminium belonged to impurities with size over 60 nm. Changes of contaminants state and concentration were explained by influence of water treatment processes and corrosion of steel water distribution pipes.
