Dutrion

Chlorine

Very high disinfection
activity against bacteria, viruses, protozoa, algae and fungi.

Low disinfection action
against viruses and protozoa.

Chlorine Dioxide exhibits
long term residual disinfection effectiveness.

Chlorine exhibits much
shorter effectiveness in water systems.

Its action is rapid and
takes 1‐10 minutes to act on microbes.

Chorine takes 1/2 ‐ 1 hour to act on microbes.

The residual effect ClO₂
remains high from starting point of dosing to the end point in supply.

Chlorine very often shows
only 20% residual at the tail end of distribution system, which means high
dosing at the front end.

Persistence of disinfectant
is very high, decomposed through hydrolysis, much slower than chlorine.

Low persistence of
disinfectant rapidly decomposed in the distribution system and low residual
levels at the tail end.

Dutrion penetrates the biofilm, strips it out and prevents re‐growth.

Chlorine in drinking
water concentrations cannot penetrate the biofilm
and hence it cannot strip biofilm.

No corrosion effect on
pipeline materials in contact and dosing pumps and other instruments in line.

Chlorine is highly
corrosive in nature, especially in combination with lower pH values.

No reaction with ammonia.

Chlorine forms toxic THM
reacting with ammonia.

No resistance building of
microbes imparted against Dutrion.

Microbes have developed
high resistance against chlorine and chlorine products.

Water taste won’t be
affected after treatment at disinfection concentrations, hence “fresh
water”.

Chlorine changes the taste
of water badly.

No smell at disinfection
levels.

Chlorine changes the odour
of water negatively.

Dutrion dosing is very flexible
and depends on optimization process. Dosing 0.05 – 0.5 ppm is common.

Typically 1‐2 ppm for drinking water disinfection, but never less than 0.5
ppm. Taste and smell issues above 2 ppm start to develop.

Broad spectrum germicidal
activity.

Chlorine presents low
efficacy and has narrow spectrum antimicrobial activity among disinfectants.

Dutrion does not release free
chlorine

It reacts with water and
generates free chlorine (HOCL) that finally acts on microbes.

ClO₂ presents
best efficacy at wide range of pH values (4‐10).

Chlorine reactions are
greatly affected with the change of pH.

Chlorine dioxide shows good
efficacy at low temperatures.

Chlorine shows low efficacy
at cold temperatures.

Chlorine dioxide shows good
efficacy at high temperatures (> 45°C.).

Chlorine shows low efficacy
at high temperatures (> 30°C).

Dutrion is not explosive in any
way.

Chlorine (gas) is very
explosive and dangerous.

Operational safety is high with
minimum precaution.

Operational safety is
low.

High efficiency to oxidize
iron and manganese compounds.

Very low efficiency to
oxidize iron and manganese compounds.

Oxidizes hydrogen sulphide,
phenol, mercaptans, cyanide, pesticides.

Chlorine is not efficient
to oxidize these substances.

Ct value for 99%
inactivation of Giardia
at 25° C. for chlorine dioxide is 7.3 mg.min/L at pH 6‐9.

Chlorine is not very
effective against Giardia.

Ct value for 99%
inactivation of Cryptosporidium at
22° C. for chlorine dioxide is 40 mg.min/L at pH 6‐9.

Chlorine does not kill Cryptosporidium.

Eco friendly, no
undesirable residues; chlorine dioxide has the future.

Chlorine destroys the
environment. Was important the last 100 years.
