Abstract
Iron pipes that distribute clean water to the community often experience corrosion and leakage. It causes dirt in the soil to enter the water flow and can cause health problems. Therefore, to provide good quality water to the community, it is necessary to control pipes’ corrosion. In previous research, there has been much discussed the bio-inhibitor corrosion in pipes, but very few have tested corrosion under real environmental conditions. Thus, this research aims to analyze the amount of reduction in the corrosion rate of clean water distribution pipes using real environmental conditions using bio-inhibitors. This study employed the same bio-inhibitor but different concentration variations. The inhibitor used came from lime peel waste with various concentrations of 120, 220, and 320 ppm. Corrosion rate testing used Potentiodynamic methods. The results showed that using a bio-inhibitor of 320 ppm could reduce the pipe’s corrosion rate by 90.7%. Before being given the bio-inhibitor, the corrosion rate was 34.690 mpy, and after being given the bio-inhibitor, it decreased to 3,225 mpy. This study’s results will later be useful for the community to utilize the bio-inhibitor as an alternative to controlling corrosion in pipes.
