【 摘 要 】

The electrical characteristics of metal pipe and CaCO3 particles in aqueous solution were investigated and a new method for anti-fouling by connecting the metal pipe with the ground was developed. The results showed that the detected electric current between the metal pipe and the ground decreased with the large-scale CaCO3 particles adhered on the inner surface of the metal pipe. The thickness of CaCO3 scale reduced about 44% by connecting the metal pipe with the ground.
