SUSTAINABILITY: DRINKING WATER → SURFACE WATER Evides DEMIN + RO ’ s Process water tank Evides (450 m³/h, G500) (10.000m³, J400) Process water tank BASF BASF DEMIN (10.000m³, A160) (1.100 m³/h, D550)
SUSTAINABILITY: DRINKING WATER → SURFACE WATER Which benefits by switching water source? 1. Reliable and redundant supply of Process water & DEMIN water ➔ Process water supply via The Netherlands (Evides) & Belgium (AWW) ➔ DEMIN water delivery via 2 suppliers (resp. J400/A160 & D550/G500) 2. Decreased production cost for Process water & DEMIN water 3. Contribution to BASF Group Goal Drinking Water: ➔ Goal 2020: Consumption -50% (30 → 15 mio m³/j) versus 2010 ➔ BASF Antwerp: Reduction of 8,4 mio m³/j versus 2010 = Reduction of >90% BASF Antwerp = Reduction of 28% BASF Group = Contribution of 56% to BASF Group Goal 4. No more use ground water for industrial processes (~3 mio m³/j)
