Aggravate equipment corrosion and shorten service life: Cause electrochemical corrosion of metal equipment, increase nutrients for sulfate-reducing bacteria, weaken the bactericidal effect of chlorine-based bactericides, and lead to equipment perforation.
Deteriorate water quality and reduce operation efficiency: Cause water to turn black and smelly, consume dissolved oxygen in water, accelerate the reproduction of anaerobic bacteria, cause fluctuations in water pH, and affect the slow-release effect.

Decrease in the alkalinity of makeup water;
Leakage of acidic materials;
Decrease in concentration ratio;
High ammonia nitrogen (converted into nitric acid and nitrous acid by nitrifying bacteria);
Unreacted hydrochloric acid from chlorine dioxide enters the circulating water system.
