Issue / Need
This drinking water supply project, in a non-electrified territory of the DRC, involved the installation of solar chlorination systems at each collection site.
These chlorine injection points were to be located downstream of two storage tanks of 1,500m3 et 600m3.
The sizing of such equipment leads to large systems.
For each site, there would be about 30 solar panels of 1,7m² and a 1200kg battery park, long cables and control cabinets to work in tropical areas. The harsh climate and operating conditions often lead to many water supply disruptions.

Approach used / Answer given
The chosen solution allows carbonation and chlorination thanks to the gravitational arrangement of the sources. This solution uses the pressure of water as a driving force. The technology proposed by DOSATRON best meets this challenge: a pump with a hydraulic motor activated only by the power of the water.
Installed directly on the pipe, the proportional dosing pumps DOSATRON operate by using the water flow rate as energy source. Pressure and flow drive the engine piston which drives the engine piston which is itself connected to a metering piston. Disinfection additives are dosed proportionally and continuously injected with water at the chosen dosage. A carbonation is performed to regulate the Ph and make the water more sensitive to the subsequent chlorination. The dose of concentrated product is directly proportional to the volume of water passing through the pump and this independently variations in the pressure flow rate of the catchment.
Located upstream of the reservoirs, chlorination effectively protects against the development of bacteria: protozoa, Escherichia Coli, Salmonella, Giardia intestinalis, Cryptosporidium parvum.... This positioning upstream of chlorination, combined with a form of adapted tank, allows to respect the contact time essential to the water disinfection
