Waste Landfill and The Waste Contamination Impact on the Corrosion Rate of Low Carbon Steel

Darmawi ^[3] | Ilhamsyah

Abstract: Landfill is a method mostly used in many cities in Indonesia to accomodate the various kind of waste produced by the community in towns. The landfill contamination is penetrating the ground, the nearby water, the bad smells and the surrounding air. The contamination is convincely promote the increment of the corrosion rate of metals. The impact of the waste landfill contamination to the corrosion rate of steel is reported in this paper. The specimen of water was taken from the Palembang city waste landfill located at Sukawinatan area positioned on 205502.6S 10404460.0E The corrosion rate of low carbon steel (LCS) has already measured by the weight loss method. The low carbon steel is immersed at the site water of the landfill and compared to the corrosion of steel immersed in aquadest solution as reference. The corrosion rate of low carbon steel immersed 336 hours in waste contaminated water is 20.5836 mpy. The corrosion rate of LCS immersed in waste contaminated water in 504 hours is 12.5983 mpy. On the other hand, the corrosion rate of LCS immersed in aquadest for 336 hours is 16, 5850 mpy and the corrosion rate of LCS immersed in aquadest 504 hours is 10.125 mpy. The results show the waste landfill contamination water ascend the corrosion rate of LCS by 25 %. The experiments also show the tendency of corrosion rate descend from time to time, which shows the ability of LCS construct the passive layer on its surface, and it is convinced as the role of chromium. The galvanic couple of LCS to zinc indicates the corrosion rate reduction significantly.
