Independent industrial water supply by digitalization, simulation and innovative treatment technologies (IndiWater)

Initial situation

  • Increasing water stress leading to limited or insufficient water availability of ground and river water with negative effects to production processes as continuous casting, hot rolling,
  • No reuse of waste waters because of to high fluctuating contents of salts, hardness and organic in effluents from emulsion, chemical, biological treatment plants and vacuum treatment
  • No suitable recovery technologies under technological or economic aspects available
  • Lak of information about flow rates, compositions and complex water systems an effective water management – upcoming problems in wastewater treatment plants could not be predicted

Project objectives

  • Water recovery from waste waters containing e.g. oil, fat, heavy metals, bacteria or particles as effluents from degreasing bath, biological/chemical treatment or gas washing water
  • Improvement of water management and treatment plant operation by prediction tool based on modelling and simulations of the different circuits using new installed digital monitoring and control systems
  • Decrease of dependency of production processes from freshwater intake by internal wastewater reuse as make up water

Innovative approaches

  • Prediction tool on basis of SIMBA#
  • Pre-filtration with new modular ceramic flat membranes for removal of organics and solids
  • Combination with desalting technologies as coated RO membranes and Membrane based capacitive deionisation to achieve near ZLD.
