[NMR Pipe Protector Verification Results] Water Supply Pipe in Binh Phuc Province, Vietnam

The red rust inside the cast iron water supply pipe has turned into black rust! It has been proven that the leaching of red rust into the water has been completely prevented.

In the Huong Canh area of the Water Supply Bureau in Binh Phuc Province, Vietnam, cast iron pipes (150A) have been in use for 15 years, leading to the progression of red rust corrosion inside the pipes, which resulted in the regular occurrence of red water. To address this red water issue, a red rust prevention device called the "NMR Pipe Protector" was installed at the base of the cast iron water supply pipes (150A). Before installation, the water color and the amount of red rust at the sampling points located 500m north, 300m west, and 600m south of the installation site were as follows: the northern point had a light brown color with 7.0 mg/l of red rust, the western point had a brown color with 8.0 mg/l, and the southern point had a dark brown color with 23 mg/l. Two weeks after installation, the northern point showed a lighter color and a reduction in red rust to 4.6 mg/l. The western point nearly lost its color, decreasing to 2.0 mg/l. The southern point changed to a light brown color with a reduction to 12 mg/l. *For more details, please refer to the PDF document or feel free to contact us.*
