Water treatment / WASH'Nutrition


An integrated approach to reduce the risk of diarrhea, parasitic infections and intestinal inflammations (or environmental enteric dysfunction) and improve nutritional impact at a low price!
Effervescent chlorine tablets (NaDCC) for water treatment at the point of use. 

Added to water in a clean container, they dissolve rapidly and release a suitable dose of chlorine. They are:
Safe: improve drinking water quality and prevent its recontamination by ensuring a residual activity of the chlorine for 24 hours. 
Effective: against a spectrum of micro-organisms*.
Better accepted than hypochlorite in terms of taste and odor of treated water. 
Easy to use, store and handle (compared to liquid forms or granules). 
Do not require any energy source or maintenance operation. 
Not considered as hazardous merchandise for transport. 

*The product is not effective against protozoans such as cryptosporidium oocysts.

Aquatabs® are effervescent chlorine tablets (NaDCC) for water treatment at the point of use


Aquatabs® tablets are broadly used for water treatment at home and in emergency situations thanks to their simplicity of use and easy deployment. 

They are intended for a healthy population aged 2 years and over. 

For young children and immunodeficient persons, in particular children with severe acute malnutrition, it is recommended to use Aquatabs® in clear water < 10 NTU (Nephelometric Turbidity Unit).

For turbid water > 100 NTU, it is recommended to carry out a physical clarification step before chlorination (coagulation/flocculation/filtration) or to double the dose of chlorine. 

Clorination inactivates most pathogens responsible for diarrhea diseases in humans. A preliminary filtration pretreatment step is required to eliminate protozoans such as cryptosporidium oocysts. 

Aquatabs® complies with European standards (EN12931: 2000) and to the specifications of WHO and the FAO for drinking water: Round I of the evaluation of household water treatment products (Household Water Treatment – HWT). 


Disinfects water: recommended doses

The tablets are available in strips of 10 tablets under different formats according to the volume and nature of the water to be treatment (measurement of the particle load per million – ppm).


Group the products: combine the products in the field


  • Access to potable water in severe-acute malnutrition treatment centers is crucial for diagnostic and follow-up activities (≈ 5 liters / consultation/ day), for hospitalized patients (ASM with complication ≈ 40 liters / day), to maintain the structure and personnel.
  • Reconstitution of therapeutic, F-75/F-100 milk requires potable water.
  • Boiling water requires combustion material and extra time.




  • Distribution of Plumpy’Nut® rations (generally 42 bags for 2 weeks) rounds out the care packages along with water-disinfecting tablets for the entire family.
  • Distribution of an additional package of water-disinfecting tablets included in the Plumpy’Nut® packages can lower the dropout rate by inspiring them to return to the health-center at the end of the treatment and to mitigate the relapse-rate (60 days on average) by extending it beyond the one-time child-treatment duration.
  • Distribution and follow-up, combined with chlorination and at-home nutritional management minimizes the cost and helps to localize interventions.




  • Diarrhea episodes can be managed via Oral Rehydration Therapy (ORT) salts which are reconstituted in potable water (2 liters of water to be consumed for two days after the first symptoms) and ZinCfant® (zinc sulfate) (tablets to be dissolved in a teaspoon of water or maternal milk).
  • Practitioners (doctors, pharmacists) can prescribe, or provide free access to, kits which can ensure potable-water throughout the diarrhea-management period, not just for the concerned child but for the entire family.



Combined plans can be proposed to Nutriset or its partners. Co-packing options will also be considered.

Aquatabs® must not be ingested.
