Corrosion Control of Drinking Water Copper Pipes by Corrosion Inhibitor


Article Preview

In case of cleaning the tap water in Korea, focus has been concentrated on how to improve water quality during the process of purification after taking in original water. However, the interest in human health has been increased, so 'secondary contamination' ,polluted in the process of crossing water reservoir, distributing pipes, indoor water tanks and water pipes after water left a filtration plant, is soared up as an important object of water quality control. Especially the copper pipe for the tap water, its characteristic was acknowledged as a pipe with many merits such as excellent corrosion resistance and easy assembly at the time to lay, is being frequently used in the advanced countries like East Europe, North America, Australia, etc, and is also being used as the material of pipe laying among the pipes for distributing water in Germany and Netherlands. But in case of Korea, the blue or green water problem is found even in the less than 6 year old copper pipes after being installed newly in indoor pipe laying for water distributing that causes to bring about aesthetic distrust to citizens, so the necessity of study is raised to control this situation. In this study tried to control the corrosion and the blue and green water problem happening in the copper pipe using corrosion inhibitors to settle down the various problems available to happen by this problem and suggested an optimized method to manage this situation.
