Prevent the reduction of residual salt concentration by converting red rust in the main water supply pipe (distribution pipe) to black rust.
The red rust prevention device "NMR Pipe Protector" converts red rust in water pipes to black rust and prevents the decrease of chlorine (residual chlorine) concentration for disinfection.
The NMR Pipe Protector has been widely adopted as a device for preventing red rust and extending the life of piping, and it has recently gained attention in the water distribution pipes of water supply authorities. At the Japan Water Works Association's water supply research presentation held in 2013, the Yokohama City Water Bureau published a paper presenting the results of a demonstration experiment showing that the use of this product can suppress the decrease in chlorine concentration in tap water. This matter was also reported as an article in the Japan Water Newspaper. The initial verification confirmed a decrease in iron ion levels in the water and an increase in residual chlorine concentration before and after installation in the water supply pipe of the public housing attached to the Tsurumi water supply reservoir. Next, a comparison of residual chlorine concentrations was conducted, revealing that before installation, the chlorine concentration was 0.5 PPM in the test pipe located 10 meters from the main pipe, 0.3 PPM at a distance of 60 meters, and 0.2 PPM at 135 meters, indicating that the residual chlorine concentration decreased with increasing distance due to red rust in the piping. After the installation of the NMR Pipe Protector, it was confirmed that the chlorine concentration at 135 meters doubled. From these test results, the effectiveness of suppressing the decrease in chlorine concentration was verified, demonstrating that the NMR Pipe Protector can also be used to prevent red rust deterioration in the main water supply pipes. *For more details, please refer to the PDF or contact us.*
