Water treatment for Africa

Arsenic treatment for water

Filter regeneration treatment process carried out by manual backwashing or adapted to the Sahelian context : robust technology with low energy cost
System installable on human-powered displacement pumps
Treatment plant for small rural drinking water supply systems
Treatment capacity from 1 to several tens of m3/hour

Reverse Osmosis Desalination for water

Brackish water systems
Customized solutions from 10 m3/d to 500 m3/d
Containerized solutions for remote areas and remote management
Energy sources : on the electricity grid, solar power (without battery) or hybridisation with a generator.

Water chlorination

Manufacture of chlorine by salt electrolysis
Mechanical or electrical dosing and injection
Energy sources : stand-alone, solar, grid or generator
Chlorine content control

Iron removal from water

Oxidation/precipitation deironing system (cascade or bubble run-off) coupled with a sand filter and, if necessary, a manganese dioxide filter for increased efficiency
The filters are regenerated by manual or automatic backwashing depending on the available energy.
Treatment capacity from 1 to several tens of m3/hour

Surface water treatment

Combination of coagulation, flocculation, bleach disinfection, sand and activated carbon filtration techniques.
Treatment of 1 to 2 m3 per hour
Autonomy (gravity), robustness (stainless steel) and ease of maintenance
