SUMMARY:Digital water management to reduce water consumption in steel production
DESCRIPTION:Due to climate change, water shortages are developing worldwide, which amplifies the existing water stress and is now also occurring regionally in European countries. This is accompanied by a change in the water composition, such as the increase in mean conductivity by a factor of 2.5 and in the chloride content by a factor of 7 in the period from 2013 to 2019 in an exemplary surface water body. The effects for the iron and steel industry, in which water is an essential process medium, are an increased demand for freshwater due to earlier reaching of the limit conductivity and an increase in corrosion in the pipe systems due to increased chloride contents. This results in the need for the development of a prognosis tool to predict emerging bottlenecks and the development of suitable methods for tapping alternative water sources to ensure the water supply.
In the application case, an integrated iron and steel works consisting of the units blast furnace, hot rolling and cold rolling mill as well as its central waste water treatment plant (CWTP) is considered in more detail. The focus of BFI-work is the desalination of the CWTP effluent using membrane-based capacitive deionization (MCDI). Furthermore, as part of the project work, the digital representation of the entire water management system with more than 20 circuits and a wide variety of water compositions was created in the SIMBA# software environment. This forms the basis for the development of the forecast simulation tool. Based on the results of the sampling and tests, various scenarios relating to the chloride content in the surface water and the effects of returning the treated effluent from the CWTP were examined using simulation technology. Further work focuses on the integration of geodata in the developed simulation model for forecasting water bottlenecks.
