[NMR Pipe Protector Verification Results] Food Processing Factory

Suppressing the growth of algae in the cooling tower! Evaporation residue has decreased from 952 mg/l to 499 mg/l.

In a food processing factory that is 11 years old, a large amount of chlorine was used to suppress the growth of slime caused by bacteria in the cooling tower. To reduce the amount of chlorine being used, an "NMR Pipe Protector" was installed. Even with the chlorine input reduced to one-third, the growth of algae in the cooling tower was effectively suppressed. Additionally, the number of general bacteria (contaminants) decreased from 640 to 270, and the turbidity value, which increases due to organic matter contamination, was significantly reduced from 8 degrees to 3 degrees, within the water quality standards. [Introduction Overview] ■ Location: Shizuoka Prefecture ■ Building Overview: 11 years old, factory ■ Water Supply Method: Pump pressurization method ■ Installation Date: October 30, 1998 ■ Installed Piping/Number of Installations: Well water pump primary side (HI-VP 40mm)/PT-50DS x 1 unit *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Effects After Installation】 ■ The amount of chlorine input was reduced to one-third while suppressing the growth of algae in the cooling tower. ■ The number of general bacteria (microorganisms) decreased from 640 to 270. ■ The turbidity value, which increased due to organic matter contamination, was significantly reduced from 8 degrees to 3 degrees, within water quality standards. ■ The consumption of potassium permanganate also decreased from 13.3 mg/l to 11.4 mg/l. ■ Overall improvement in water quality led to a reduction in evaporation residues from 952 mg/l to 499 mg/l. ■ Nitrite nitrogen carried by organic matter was significantly reduced from 13.2 mg/l to 4.7 mg/l, within water quality standards. *For more details, please refer to the PDF document or feel free to contact us.
