SPENT PICKLING LIQUOR REGENERATION AND LIQUID WASTE MINIMIZATION THROUGH ACIDS, ZINC AND FERROUS SULFATE RECOVERY
Zero liquid discharge
Recovery of raw materials
Enormous cost savings and return on investment
The development of LIFE DIME was possible thanks to three organisations:
LIFE is an entity established by the European Commission with the mission of financing the development of high valued-added projects dedicated to protecting the environment and fighting climate change.
Condorchem Envitech is an environmental engineering firm that specialises in the treatment of industrial waste water and emissions. Its mission within the project is to design the process and solution for application on an industrial scale.
Ecotechno is a manufacturer of machinery for treating liquid waste. Therefore its main responsibility in the project is the production and supply of the necessary equipment to implement the solution.
The main objective of the LIFE DIME project is to validate the Chemirec® technology on an industrial scale.
Chemirec® is an innovative, highly effective solution for the treatment of liquid waste in metal surface finishing industries. It has been patented by Condorchem Envitech and developed on an industrial level thanks to the collaboration of LIFE and Ecotechno.
By demonstrating the validity and efficacy of the Chemirec® technology in the treatment of liquid waste generated by spent pickling baths, LIFE DIME contributes the following benefits to the metallurgical and steel industries:
Elimination or reduction of the liquid waste to be treated and hence, its management costs.
Recovery of more than 95 % of the hydrochloric acid (HCl) in the spent baths for its reuse in new baths.
Obtaining of recoverable elements such as iron (Fe) and zinc (Zn) for their reuse or sale.
Provision of a technological solution that brings a rapid return on investment, is environmentally sustainable and extremely efficient in the treatment and recovery of waste.
Apart from the benefits that the LIFE DIME project brings to companies that put their faith in this solution, it also complies with the requirements established by the IPCC Directive to be recognised as one of the BATs (Best Available Techniques), in other words, those that are technologically relevant due to their efficacy, present no availability problems and offer the following social benefits:
