chemical stability
trend that all kinds of components of the treated water possibly have reactions during the water distribution, storage or use processes (e.g. deposition of calcium carbonate and the formation of disinfection (3.21) byproducts) and the scaling, fouling and corrosion effects on pipes and equipment to which the water is exposed (e.g. release of toxic and harmful chemicals from the surface of nonmetallic pipes, corrosion on the surface of metallic pipe)
