1. Sodium chlorate produces chlorine dioxide. The chemical reaction formula is as follows:

Main reaction: NaCLO3+2HCL↑CLO2+1/2CL2+NaCL+H2O

Side reaction: NaCLO3+6HCL↑3CL2+NaCL+3H2O

 

2. Sodium chlorite produces chlorine dioxide, the chemical reaction formula is as follows:

5NaCLO2+4HCL↑4CLO2+5NaCL+2H2O

 

The raw materials for the above reactions are accurately metered by their respective metering devices and then fed into the reactor.

The reaction generates chlorine dioxide gas, which is sucked by the jet and mixed with water to make an efficient chlorine dioxide disinfectant.

 

Features

 

1. Adopt advanced raw material formula, high conversion efficiency, sodium cyanate above 70%, sodium chlorite above 95%.

2. Compact design structure, small floor space, simple operation, simple and safe maintenance, and long service life.

3. The degree of automation is high. The control system can automatically adjust the dosage according to the change of water quality, and is equipped with various safety protection measures such as water shortage and no medicine shutdown.

4. Complete specifications and varieties, chlorine dioxide generator from 50g-20000g/h.

1. What is stabilised Chlorine dioxide?
Like ozone and chlorine, chlorine dioxide is an oxidizing biocide and not a metabolic toxin. This means that chlorine dioxide kills microorganisms by disruption of the transport of nutrients across the cell wall, not by disruption of a metabolic process.
Stabilised chlorine dioxide is ClO2 buffered in an aqueous solution. Adding an acid to the required concentration activates the disinfectant.

2. How does it work?

Of the oxidizing biocides, chlorine dioxide is the most selective oxidant. Both ozone and chlorine are much more reactive than chlorine dioxide, and they will be consumed by most organic compounds. Chlorine dioxide however, reacts only with reduced sulphur compounds, secondary and tertiary amines, and some other highly reduced and reactive organics. This allows much lower dosages of chlorine dioxide to achieve a more stable residual than either chlorine or ozone. Chlorine dioxide, generated properly (all chlorine dioxide is not created equal), can be effectively used in much higher organic loading than either ozone or chlorine because of its selectivity.

3. How effective is it?

The effectivety of chlorine dioxide is at least as high as chlorines, though at lower concentrations. But there are more and important advantages.

The bactericidal efficiency is relatively unaffected by pH values between 4 and 10;
Chlorine dioxide is clearly superior to chlorine in the destruction of spores, bacteria's, viruses and other pathogen organisms on an equal residual base;
The required contact time for ClO2 is lower;
Chlorine dioxide has better solubility;
No corrosion associated with high chlorine concentrations. Reduces long term maintenance costs;
Chlorine dioxide does not react with NH3 or NH4+;
It destroys THM precursors and increases coagulation;
ClO2 destroys phenols and has no distinct smell;
It is better at removing iron and magnesia compounds than chlorine, especially complex bounds;

 

 

What is Chlorine Dioxide?
Chlorine Dioxide has the chemical formula ClO2 and is a yellow to brown coloured gas at room temperature and pressure. It is a highly reactive oxidant and for all practical areas of water disinfection, it must be generated on site using proprietary reaction and dosing equipment.
 
Solubility
Chlorine Dioxide is approximately 5 times more soluble than chlorine and 50 times more soluble than ozone. Even though Chlorine Dioxide is soluble, it is still a gas and the solubility of the gas is governed by Henry’s Law. In closed pipelines, virtually no loss out of water into the gas phase can be expected. In open tanks, Chlorine Dioxide in solution will slowly decrease until equilibrium is established between ClO2(g) and ClO2(aq). According to Le Chatelier’s Principle, if Chlorine Dioxide is continually removed from the gas phase above an open tank, the concentration in solution will continue to decrease until it reaches zero.
 
Generation Reactions
There are a large number of Chlorine Dioxide generation reactions. However, not all of these are commercially suitable for water treatment or water disinfection. The following four are the most common. Please click on the links for information on systems we provide
 
Electrochemical
① Anode (oxidation): ClO2– → ClO2 + e–
② Cathode (reduction): 2H2O + 2e– → H2 + 2OH–
① + ② (combined) 2ClO2– + 2H2O → 2ClO2 + H2 + 2OH–
 
Acid-Chlorite 5NaClO2 + 4HCl → 4ClO2 + 5NaCl + 2H2O
 
Chlorine-Chlorite Cl2 + H2O → HOCl + HCl
 
Then refer three chemical reaction below
Three Chemical 2NaClO2 + HOCl + HCl → 2ClO2 + 2NaCl + H2O
 
In the 2-chemical acid-chlorite reaction, excess acid is used to drive the reaction to completion . In the chlorine-chlorite reaction, a small excess of chlorine (approx. 10%) is used. The excess reactant continues through into the water when chlorine dioxide is dosed. In the 2-chemical acid-chlorite reaction, excess acid will be dosed into the water with the chlorine dioxide, which may necessitate pH correction afterwards. The positive aspect of this reaction, is that the chlorine dioxide produced is chlorine free. In the chlorine-chlorite reaction, chlorine will be present with chlorine dioxide in the treated water. The presence of chlorine will produce chlorinated organic reaction by-products which are not desired. The electrochemical reaction only requires one precursor chemical and electrical power and has by-products of caustic and hydrogen.
