"purification process of purifying Philippine clams in the oxygenated state with 4 times of disinfected seawater...) was explored, and the water was changed once for 8 hours, and the purification time was 24 hours. The pilot test of the process can reduce the number of E. coli population in the Philippine Hazai intestine... and the sterilization rate reaches about 95%, the sand content is reduced from 65mg/100g to 23mg/100g, and the volatile salt-based nitrogen rises from 3.8mg/100g to 5.8mg/100g," "phenolic compounds denature proteins and make microorganisms inactive, and also different from chlorine biochlorination and inactivity. When it comes into contact with microorganisms, it releases new ecological oxygen and hypochlorous acid molecules and produces a powerful bactericidal and disinfection effect. This strong oxidation effect makes the amino acids in microorganisms oxidize and decompose, so as to inhibit their growth and kill them. Its residues water, trace chloride, carbon dioxide, organic sugar and other non-toxic and harmless substances." "According to the experimental results of Chen Youlin [2], the mass fraction of chlorine dioxide only needs to be 10× 10-6 action for 5 minutes to completely kill E. coli, mass fraction 10× 10-6 action to completely kill Staphylococcus aureus, mass fraction 100× 10-6 action 10min to kill spore bacteria, mass fraction 500× 10-6 for 2min to destroy hepatitis B virus (HBSAG); Chlorine dioxide can also have a special decomposition effect on cyanide, etc"

Corrosivity of Chlorine Dioxide Used as Sanitizer in Ultrafiltration System
Corrosivity of Chlorine Dioxide Used as Sanitizer in Ultrafiltration System
"applications in which soil residues are frequent." "One sanitizer was an acidified solution of dilute sodium chlorite at pH 2.7; the other sanitizer was dilute chlorine dioxide (about 15 ppm) in tap water. Stainless steel types 304 and 316 corroded rapidly when exposed to the acidified chlorite solution. Chlorine dioxide near neutral pH 7.2 was noncorrosive to both type 304 and 316 stainless steels at a concentration of 100 ppm during 10 d of continuous exposure. This concentration is well above the typical use Concentration of 15 ppm; typical use time span is 15 min." "chlorine dioxide is of equal bactericidal activ- ity to sodium hypochlorite at one-seventh the concentration of hypochlorite, when used for sanitation of poultry processing water"
