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
