“…For example, the water needed to generate electricity for the steel mill would be considered virtual water for this enterprise. Gao et al (2011) applied substance flow analysis to establish an evaluation index for the water use systems of steel enterprises. The index system includes WC per tonne of steel, FWC per tonne of steel, recycled WC per tonne of steel, and water losses per tonne of steel.…”

“…As far as the PI is concerned, over the last few years, some important results have been achieved in the energy [17] and water fields, through theoretical studies, pinch analyses [18], experimental campaigns and the use of PM and S [1,[19][20][21]. In addition, in order to reduce water consumption and wastewater discharge, an optimization model and an evaluation index system for the water-use network of a steelwork has led to important results in water savings [22]. The implementation of PI-based solutions at the industrial level can limit the overall water consumption by reducing the water withdrawal [23][24][25][26].…”

Abstract:In the steel sector water management aims at improving the sustainability of the production cycle, resulting in resource efficiency benefits and in reduced water demand and costs. To be reused, water needs to be cooled and desalinized to avoid salt concentration in water circulation systems. The presented work includes two case studies carried out in an integrated steelmaking plant, respectively, to evaluate the possible implementation of ultrafiltration and reverse osmosis to reduce salt concentration in water streams and to investigate, through modelling and simulation, a process integration solution to improve water efficiency. Results showed that most salts are removed by reverse osmosis and that its coupling with ultrafiltration allows obtaining very high quality water; reuse of desalinated wastewater resulted in being more suitable and economically viable than its discharge. Moreover, modelling and simulation showed that the considered blowdown could be reused without significant changes in the receiving water network area. The industrial implementation of water recovery solutions can lead to a decrease of fresh water consumption, effluent discharge, and to improvement of product quality and equipment service life. The considered desalination technologies are transferable and easily implementable, and modelling and simulation are very useful in order to evaluate process modifications before real implementation.

“…Resources saving, emission reduction and environment protection have become the strategic need of existence and development of the industry, but also the urgent request of meeting challenge and improving market competition. Water as the source of life, industrial blood, is known as the "the blood of iron and steel production", which is both a resource and an energy source, has an irreplaceable role in the process of iron and steel production [1][2][3].…”
