The combination of chlorine dioxide and sodium hypochlorite for disinfection of drinking water could achieve better effect of disinfection and decrease disinfection by-products as well.

Sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) are commonly used for household water treatment (HWT); chlorine dioxide (ClO2) is a potential new HWT option. We compared the residual maintenance of NaOCl, NaDCC, and ClO2 over 24 hours using recommended dosages (2 and 4 mg/L) in waters of varying turbidity (0-300 NTU, from kaolin clay or creek-bottom sediments) and total organic carbon (TOC) concentrations (0-100 mg/L), for a total of 324 reactors. NaOCl and NaDCC had similar free chlorine decay rates, and ClO2 decayed more rapidly across all of the tested conditions. Little variability was observed across clay-based turbidity levels and TOC concentrations. With a dosage of 2 mg/L, a residual ≥0.2 mg/L was maintained at 30 NTU for NaOCl and 100 NTU for NaDCC; for ClO2, 4 mg/L were required to maintain ≥0.2 mg/L under all conditions except at zero turbidity. Comparisons with data from the literature suggest that the three compounds would inactivate E. coli, rotavirus, and Giardia cysts within 1 hour under all conditions, except 300 NTU for NaOCl and NaDCC. All three disinfectants are similarly efficacious for this usage; however, differences are seen in decay rates that may influence disinfectant selection depending on water storage time.

"Chlorine dioxide was more effective against Aphanomyces sp. than S. diclina and A. bisexualis. Three days of immersion in chlorine dioxide >100 ppm inhibited hyphal growth of S. diclina and A. bisexualis, and concentrations >50 ppm inhibited growth of Aphanomyces sp. Immersion in 500 μg/ml chlorine dioxide for 1-4 h killed the hyphae and concentrations of 32 to 63μg/ml inhibited germination and killed zoospores of all three strains. The result suggest that treatment of hatchery water with 63μg/ml of chlorine dioxide for 10 min can control the zoospores but does not inhibit the growth of fungal hyphae of these strains. We conclude chlorine dioxide is an effective antifungal agent on both the hyphal and zoospore stages of S. diclina, A. bisexualis and Aphanomyces sp."

A few of the common questions posed about the use of ClO2 in oilfield operations are answered.

"ClO2 has been well recognized as the green biocide with high efficiency in controlling biofilms, hydrogen sulfide (H2S), iron sulfides, and microbially influenced corrosion (MIC). Treatment with ClO2 is one of the preferred methods for flowback and produced water. In waterflood systems with comingles of produced water and freshwater, the presence of biofilms harbors sulfate-reducing bacteria (SRB) and acid producing bacteria (APB) in the pipelines connecting the produced water treatment and blend facility to the waterflood injection wells. The presented results indicate that a combination of ClO2 and TTPC provides a cost-effective biological control of the waterflood and saltwater disposal systems."

"... How long does it take for these tablets to purify the water? Answer: 30 min to kill bugs in clear good looking water, 4 hours to the real nasty ones like giardia and cryptosparidum in "turbid" water (meaning murky or full of debris, aka the type of water you'd really want to use tablets on)"
