[PARTNER ARTICLE] While 320 million people in Africa still lack safe drinking water, chlorine has been used for more than a century to disinfect drinking water. Not without reason: it is an efficient, economical and safe process. Present in Africa for about thirty years, the French group Gazechim has made it its forte.

Present in Africa for some thirty years, particularly for water treatment, the French company Gazechim is a major supplier of chlorine gas on the continent. The volumes are quite large, especially in West Africa, where chlorine gas is used for drinking water (and, incidentally, for the manufacture of disinfectant). In the sub-region, Gazechim’s turnover, which is on the rise, is close to one million euros. This is for at least three reasons: the quality and reliability of the solution proposed by Gazechim, population growth on the continent and, at the same time, the number of treatment plants that are steadily increasing.

Chlorine gas, a safety guarantee for water disinfection

National water companies, or even large water treatment companies, use Gazechim’s drinking water treatment solution, because chlorine gas has several advantages.

1. The effectiveness of the treatment, which guarantees microbiologically potable water, whose effect is persistent and therefore ensures disinfection over time. Chlorine gas is effective against microorganisms and eliminates germs in water. In addition, it is a very simple product to use, which guarantees the smooth running of processing operations.

2. Chlorine gas offers a safe chlorination process that functions as an alarm signal for water quality. Gazechim also ensures continuity in the event of an influenza pandemic and therefore guarantees total health quality.

3. The economic aspect of the proposed solution, with a product that induces an economic workforce, an availability at all times, that is stable over time and does not produce any waste since the packaging is exchangeable.

In addition, Gazechim’s specific know-how in a business where, as Hervé Chometon, Export Manager at Gazechim, points out, logistics plays a decisive role. Since 1937, the company has been packaging liquefied gases. As a result, highly qualified specialists secure the entire process in two conditioning centres adapted to liquefied gas treatment and five distribution platforms, not to mention direct intervention at the customer’s premises and local team training.


This expertise and the accompanying certifications have enabled Gazechim to provide a turnkey solution that secures the entire supply chain, avoiding several risks:

– Fouling of dosing pumps downstream chlorine bottles when using lower quality products, to avoid the extra cost involved.
– Energy costs in the event of local production of chlorine from salt, which again weighs on the final profitability.
– In the event of bleach use, the loss of concentration of the product, over time and in contact with light, which forces to buy back volumes, while Gazechim’s chlorine gas remains perfectly stable.
– Even more serious, if calcium hypochlorite is used, as the product is not very stable in case of humidity and heat, explosions could occur during the transport….

A more cost-effective and environmentally friendly approach

Finally, Gazechim’s boat rotation supply system with heavy-duty one-tonne cylinders avoids throwing chlorine-soiled metal tanks on site, which would end up polluting the environment with a significant risk to health.

Present in Senegal, Ivory Coast and Morocco, Gazechim is able to deliver chlorine gas for drinking water treatment in all territories near the coast in Africa, from Ghana to Ethiopia, via Equatorial Guinea. Especially since African professionals are now more concerned about the durability of the equipment and are therefore interested in quality products that preserve equipment and improve profitability in the medium term.
