SUSTAINABILITY: DRINKING WATER → SURFACE WATER

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)

Application 2: Condensate treatment

→ GOAL: reliable & alternative technology → GOAL: decrease # regenerations with chemicals (HCl, NaOH)

IMPROVED @ BASF Antwerp

Depending on TOC composition ≠ organic acids formed with different corrosion effects

Study corrosion effects of organic acids
