H²O Combi-DES


Safe and powerful drinking water disinfectant


 The combination of the two H²O Combi-DES components generates a 99.9% pure chlorine dioxide solution, without any chlorine or other harmful by-products.

The easy to use product is developed to effectively disinfect drinking water at a low dosage to make water a safe and valuable nutrient for poultry and livestock.


 Benefits of H²O Combi-DES:

-          Prevents the formation of biofilm by dosing continuously 

-          Is not corrosive to the drinking water system after dosing

-          Is pH-independent (effective at pH 2-10) 

-          260% more effective than a chlorine based disinfectant

-          Reacts directly with the cell wall of micro-organisms, so no resistance occurs

-          Does not form any toxic by-products

-          Does not affect the smell and taste of the water



The combination of the two H²O Combi-DES components generates a 99.9% pure chlorine dioxide solution.


Active Substance component A:                                                                                           

Sodium Chlorite (NaClO2)           1.3%


Active Substance component B:                                                                                           

Sodium Bisulfate (NaHSO4)        31%

Hydrochloric acid                           0.015%



H²O Combi-DES consists of two separate precursors, H²O Combi-DES component A  (Sodium Chlorite) and H²O Combi-DES component B (Sodium Bisulfate), that may only be used in this combination without combining other products. The prepared concentrate is used for drinking water disinfection and prevention of biofilm in an in use system. The product may only be applied using appropriate dosing equipment for disinfection of water systems and drinking water in professional animal husbandry.


Prior to the use of the product, the system should be thoroughly cleaned, after which the cleaning agent and contamination should be flushed away entirely.


 Preparation of the concentrate:

Always wear protective clothing, gloves and respiratory protection  when preparing the concentrate. Add component B (the white 1 Litre bottle) to component A in the blue 20 Litre drum and close the drum immediately and shake it gently. Wait 60 minutes for the reaction to take place. The hereby prepared solution should be used within 30 days after blending and stored in the original packaging in a cool place.


Dosage and administration of the prepared concentrate:

prevention of biofilm in an in use system:

Regular dosage: 50 – 100 ml / 1000 L water, depending on the germ pressure

Duration: Continuously

After using additives:

Dosage: 150 – 200 ml / 1000 L water

Duration: 3 consecutive days


The concentration of Chlorine Dioxide in the drinking water should never be higher than 0.2 ppm. The concentration should be measured frequently at the first drinking source using test strips or a colorimeter.



The product may not be used in combination with oral vaccination via drinking water. Stop using H²O Combi-DES at least 24 hours prior to vaccination and do not start using it before 24 hours after vaccination.


 Statutory instructions for use:

The product  may only be used for combating bacteria (excluding bacterial spores and mycobacteria), fungi and yeasts in drinking water and drinking water systems exclusively used for the benefit of animals. The active substance Chlorine Dioxide is to be produced using the two precursors; H²O Combi-DES component A (Sodium Chlorite) and H²O Combi-DES component B (Sodium Bisulfate). Following the general directions for use, a controlled reaction should take place in the original product packaging.

To avoid the reduced performance of individual wastewater treatment when usage at the farm, waste that contains the product has to be discharged in the manure pit or sewer that is connected to the sewerage system.

The product is for professional use only.



Store closed in a dry place at 15-25 °C.
