Description
According to the European Water Framework Directive (2000/60/EC), conservation and enhancing the aquatic environment is one of its key objectives. It has been shown that HC, oil, fat and heavy metals are found in increasing frequency in many aquatic organisms in Europe and are difficult to remove with conventional water treatment technologies. For this purpose, TECNIMOEM is implementing this project with the aim of reducing the amount of wastes generated during degreasing and phosphating processes in the paint line. As a result, obtained residual water will fulfill the requirements laid down in current European legislation and the transfer and treatment through an authorised agent (currently necessary) will be avoided. To achieve this aim, the project will consist of the study and development of a filtration system to remove not only the oil, fat and HC obtained during degreasing of metallic pieces but also micro-contaminants (heavy metals) generated during degreasing-phosphatizing process.
Summary of project results
In this sense, TECNIMOEM, constantly in the pursuit of excellence, proposed the execution of the present project with the aim of reducing the amount of wastes generated during degreasing and phosphating processes in the paint line. As a result, obtained residual water will fulfil those requirements laid down in current European legislation (91/271/EC y 200/60/EG) and the transfer and treatment through an authorised agent (currently necessary) will be avoided. To achieve this aim, the project has consisted of the study and development of a filtration system to remove not only the oils, fats and HC obtained during degreasing of metallic pieces but also micro-contaminants (heavy metals) generated during degreasing-phosphatizing process by two innovative technologies based on the use of an absorb material in the first stage of filtration and nano-resins of PAA/CD in the second stage.
