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.
