Suppressing the growth of algae in the cooling tower! The evaporation residue has also 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 dosage reduced to one-third, the growth of algae in the cooling tower could still be suppressed. Additionally, the number of general bacteria (microorganisms) decreased from 640 to 270, and the color value, which increases due to organic matter contamination, was significantly reduced from 8 degrees to 3 degrees, within the water quality standard. 【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.
