Organosilicon & White Carbon Black
Description
Wastewater from organosilicon and white carbon black production is treated to recover water and convert sodium sulfate into sulfuric acid and caustic soda.
Process
- Pre-treatment removes silicon compounds.
- Membrane systems recover water and concentrate brine.
- Bipolar membrane electrodialysis converts sodium sulfate into sulfuric acid and sodium hydroxide.
Applications
- White carbon black production.
- Organosilicon manufacturing.
Key Advantages
Achieves near-complete resource utilization.
Enables water and material recycling.
Supports sustainable production processes.
