The
Pall Aria Pure systems will provide an independent water source for more than 3000 people in the Ndiaffate and Dankh Sene villages, from October 2011.
The Pall Aria Pure unit is an easily transportable, manual, low-pressure reverse osmosis (RO) system engineered for TDS (total dissolved solids) removal - including fluoride - from well water. It can produce 500 litres of pure water every hour.
The installation of the Pall water systems comes after an 18-month pilot test involving more than 1000 hours of on-site testing under harsh conditions.
A study by the University of Dakar found that the concentration of fluoride ions in underground water in Senegal ranges between five and 15 times the acceptable standard (0.7 milligrams per litre).
