Sodium-hypochlorite vs. EOXIDE LQ 75

Chlorine is the most common chemical disinfectant but the question is: Is disinfection with chlorine really safe and reliable?

Sodium-hypochlorite

eOxide® LQ 75 solution

Sodium hypochlorite used for water disinfection (professional use) contains between 10% -15% active ingredient.

eOxide LQ 75 is a 99% pure chlorine dioxide in a 0,75% solution which contains no free chlorine and chlorite when dosed into the water.

Sodium hypochlorite generates hazardous byproducts like THM’s , HAA’s and Mutagen X in contact with organic material in the water. These by products are very strongly linked to cancer.

eOxide LQ 75 will not generate hazardous byproducts in contact with organic material in the water. Rest products of eOxide LQ 75 0.75% are sodium sulfate and sodium chloride. These levels are NEGLIGIBLE.

Sodium hypochlorite can be dosed in the water by using standard dosing pumps. Residual levels can be measured by membrane sensors and/or photometer.

eOxide LQ 75 can be dosed in the water by using standard dosing pumps. Residual levels can be measured by membrane sensors and/or photometer.

Sodium hypochlorite is strongly pH dependant and is efficient by pH 7 to 7,5. pH level of the water has to be balanced and corrected for disinfection reasons.

eOxide LQ 75 works 100% effective between pH 4 and pH 10 and does not have to be corrected or balanced for disinfection reasons.

Sodium hypochlorite is very corrosive for all kinds of materials, pipes and dosing equipment.

eOxide LQ 75 0.75% solution is NOT corrosive when dosed into the water only when the pH of the water is <4.

Sodium hypochlorite is not selective and reacts with all kind of organic materials present in the water and is consumed very fast for this reason.

eOxide LQ 75 is highly selective and for this reason it will remain active for a long time in the distribution network. This implies that a long residual function of eOxide LQ 75 can be achieved (up-to 72 hours) in water distribution systems. This is LONGER than sodium hypochlorite.

Sodium hypochlorite is not effective in removing a bio-film and preventing the growth of a bio-film in storage tanks and/or distribution systems. A shock dose with sodium hypochlorite can damage the material of the tank/pipes because it is highly corrosive.

eOxide LQ 75 is highly effective in removing a bio-film and preventing the growth of a bio-film in storage tanks and/or distribution systems. A present bio-film can be removed by a shock dose of 30 mg/l and a contact time of 8 hours. A low continuous dosage (0,05 to 0,2 mg/l) will prevent the re-growth of the bio film. A shock dose will not damage the material of the tank/pipes because the product is not corrosive when dosed into the water.

Sodium hypochlorite will not remove taste and smell problems generated by algae and phenols.

eOxide LQ 75 is very effective to remove taste and smell problems generated by algae and phenols.

Resistance building is possible by microorganisms against Sodium hypochlorite. Example: Cryptosporidium, Listeria and Legionella.

eOxide LQ 75 kills all waterborne microorganisms and resistance building is not possible.

Sodium hypochlorite is dosed in general between 1 and 5 mg/l to disinfect drinking water. A dosage of 3 mg/l of a 10% concentration consumes 30 ml of sodium hypochlorite per 1000 liter of water.

eOxide LQ 75 is dosed in general between 0,05 and 0,2 mg/l to disinfect drinking water. A dosage of 0,1 mg/l consumes 13,3 ml of product per 1000 liter of water. In most applications a 2/3 reduction of chemical dosage compared to Sodium hypochlorite is realistic.
