Resumen:
Una empresa checa especializada en actividades de investigación e innovación en el campo de procesos de membrana ofrece un dispositivo para purificar ácidos orgánicos diluidos contaminados por iones metálicos y reutilizar el ácido en procesos tecnológicos. La tecnología está especialmente indicada para industrias que hacen un gran uso de ácidos orgánicos diluidos, como es el caso de la industria de tratamiento de superficies metálicas. Esta tecnología ha sido probada para purificar ácido sulfúrico, ácido clorhídrico y ácido nítrico. En comparación con el método de purificación convencional (retardación), el método de diálisis de difusión consume un 40% menos de agua y las aguas residuales se contaminan un 40% menos por el ácido. Los costes de limpieza se reducen alrededor de un 41%. La empresa busca socios con el fin de establecer acuerdos comerciales con asistencia técnica.

Developer of a device that purifies diluted inorganic acids contaminated by metal ions seeks commercial agreement with technical assistance
Summary:
A Czech company that focuses mainly on research and innovation activities in the field of membrane processes, offers a device suitable to purify diluted inorganic acid, contaminated by metal ions and thus reuse the acid in technological processes. The technology is suitable particularly in industries with high use of diluted inorganic acids e.g. in the metal surface treatment industry. The company is looking for partners for commercial agreement with technical assistance.
Description:
Currently inorganic acids like, for example sulphuric acid, are being contaminated during their use in treatments of metal surfaces. Their liquidation is challenging and costly. For example, standard method of purification - retardation/passivation - consumes 40% more water while wastewater is roughly 40% more contaminated by the acid.

The novel technology on offer is particularly effective in recovering the electrolyte - diluted inorganic acid (e.g. H2SO4) is after technological process of passivation contaminated by residues of treated metal (e.g. Al2(SO4)3 when aluminium is treated). Contaminated electrolyte needs to be replaced and liquidated.

By diffusion dialysis metal ions dispersed in electrolyte are separated by membrane into water which leads to the electrolyte´s purification. The final outcome is purified electrolyte up to 90%, solid waste (salts) and waste water, containing most of the metal ions. Solid salts can be stocked in the dump or disposed by a professional company. Water can be treated by waste water treatment plant.

The technology is tested for purification of the sulphuric acid, hydrochloric acid and nitric acid.
The company is looking for a partner active in metal surface treatment industry for collaboration on installation and commissioning of the technology on the basis of a commercial agreement with technical assistance.
Advantages and Innovations:
The process is highly efficient and environmentally friendly.
Compared to the purification of the same volume of acid by the standard method of purification - retardation, diffusion dialysis consumes 40% less water, wastewater is for 40% less contaminated by the acid, the amount of solid waste is reduced by about 15%. Operating costs for cleaning are significantly reduced by about 41%. The company offers detailed testing of the customer´s waste acid for the suitability for cleaning by diffusion dialysis.
