Initial situation: Some steelworks experiences problems with product deficiencies like slivers and cracks. Several pre-studies indicated a relationship between the time […]
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.
