Initial situation: The initial solidification of the molten steel is important for determining the quality of the cast product Rim formation […]
INSPIREWATER – Innovative Solutions in the Process Industry for next generation Resource Efficient Water management
Initial situation
- Process related intake of scale, formation of hardness and salting (rolling mill cooling water) or metals in pickling acids/rinsing water avoiding/limiting internal reuse
- High fouling potential of effluent of water treatment plants avoiding internal reuse (zero liquid discharge)
- Implementation of alternative heat sources for separation by using waste heat
Project objectives of the steel case
- Reduction of water consumption and waste water production about 30 %
- Energy saving of 15 % by including use of waste heat
- 20 % validated increased recovery of materials (metals and phosphorous)
Innovative approaches
- Establishment of an Holistic water and resource management system
- Systemic configuration and technology adaptation
- Demonstration of new technologies and combinations for sustainable water treatment (e.g. magnetic separator and electro-precipitation for softening with simulations disinfection)
- Economic assessment, exploitation
