ANGERS, France (49)
36 blocks of 24 modules AC1125 (2006)
Angers and surrounding towns are supplied from the waters of
the river Loire and the alluvial table.
These waters are loaded with particles (suspended and colloidal
matter, algae), organic matter, micro-organisms, kysts, bacteria
and metals (Fe, Mn).
To eliminate the bulk of this pollution, Aquasource membranes
are associated with Cristal® process of powdered activated
carbon.
• The water :
Turbidity : 5 to 100 NTU
Iron : < 0.05 to 2 mg/L
Manganese : 0.05 to 0.3 mg/L
T : 5 to 25°C
pH : 7 to 9.7
TOC : 3 to 8 mgC/L
KMnO 4 demand : 2.5 to 9.5 mgO2/L
