Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (2)
The Yokohama City Waterworks Bureau has verified the effectiveness of the "NMR Pipe Protector" for preventing the decrease in residual chlorine concentration in water distribution pipes.
The Yokohama City Waterworks Bureau confirmed an increase in residual chlorine concentration to prevent red rust and the associated reduction of disinfectant chlorine in the water supply pipe at the Tsurumi public office. Therefore, starting from November 5, 2012, a demonstration test was conducted using the water distribution pipe (100A) in the Hazawa area to prevent the decrease in residual chlorine concentration. In the six measurements taken from September 26 to October 30, prior to the installation of the NMR pipe protector, the average residual chlorine concentration at the planned installation site (Point A) was 0.55 mg/ℓ (with Point A's residual chlorine concentration set at 100%). However, at 50 meters downstream (Point B), the average was 0.41 mg/ℓ (a reduction rate of 25.45%), and at the farthest point, 125 meters away (Point C), the average was 0.23 mg/ℓ (a reduction rate of 58.18%), indicating a decrease due to the red rust occurring in the piping. Subsequently, on November 5, the NMR pipe protector was installed, and after more than three months, during the three measurements taken from February 19 to March 22, the average residual chlorine concentration at the installation site (Point A) was 0.61 mg/ℓ. At 50 meters downstream (Point B), the average for the same three measurements was 0.61 mg/ℓ (a reduction rate of 0%), showing that the decrease was mostly prevented. Even at the farthest point, 125 meters away (Point C), the average for the same three measurements was 0.55 mg/ℓ (a reduction rate of 9.84%), indicating a significant improvement in the reduction rate.

basic information
The Yokohama City Waterworks Bureau has verified that by using NMR pipe protectors, it can prevent red rust inside the water supply pipes, similar to the building's water supply pipes, and as a result, prevent the reduction of disinfectant chlorine in the main water supply pipes (distribution pipes). The results of this trial were presented as an administrative paper titled "Verification of the Effect of a Rust Prevention Device Using Specific Electromagnetic Waves on the Prevention of Residual Chlorine Reduction in Distribution Pipes" at the 25th Annual National Conference of the Japan Water Works Association held in Koriyama City, Fukushima Prefecture, starting from October 23, 2013.
