ArcelorMittal Global R&D has presented the results of its initial tests of innovative technologies and evaluation of alternative water resources, which it hopes will increase water recovery at the group’s plants, to SpotView consortium partners from Finland, France, Greece, UK, Germany, Luxembourg, Belgium, Holland and Spain.
The objective of the SpotView project is to develop and demonstrate innovative, sustainable and efficient technology and processes which optimise the use of natural resources, especially water, in three industrial sectors: dairy, pulp and paper and steel.
The SpotView consortium covers the whole value chain in these sectors, from technology development to industrial applications. ArcelorMittal Global R&D and Düsseldorf-based BFI Technological Centre are collaborating to lead the research into such technologies for the steelmaking industry, as well as, developing synergies with other industrial sectors.
The innovative technologies they will evaluate for the steel sector as part of this project are:
- capacitive deionisation to reduce water salinity; and
- a hybrid process for flotation and submerged microfiltration for the removal of suspended solids as well as oils and grease. By combining two treatments into one step, they hope to improve water quality and reduce the footprint of the process.
Both technologies are very versatile and could be applied to various types of production sites facing water restrictions, or needing to upgrade to their water treatment plants.
