Abstract

Influence of altering magnetic field on chemical properties of water, scale formation and morphology was studied using polyethylene and copper pipes located both in a laboratory pilot-system and in an apartment complex formed by five different buildings each having four or five different homes. In the pilot network, magnetic field decreased calcium scaling by 15% in the both studied piping materials. Also, surface film on the copper pipe appeared to be less compact by the magnetic exposure. In the studies conducted in the apartment complex, magnetic field effectively mobilized earlier accumulated iron and copper from the copper pipe surfaces especially dealing with a hot water circuit.
