Cold Atmospheric Plasma treatment of effluents in the food industry

One of the main problems that affect the environmental sustainability of the food industries is the generation of wastewater from this sector.

To eliminate the effluents produced in these industries and comply with the regulations, a large amount of energy is necessary, since the impact of these wastewater has a significant pollutant index that can be detrimental to aquatic biodiversity. Therefore, the search for innovative methods to treat and alleviate these polluting excesses in the environment, in an energy efficient way, are not only necessary, but also increasingly urgent.

In recent Cold Atmospheric Plasma (CAP) research on synthetic dairy and meat effluents, dielectric barrier discharge treatment has been evaluated to control the key microbial load found in the effluents produced by these large industries. Therefore, aquatic bioassays have been carried out to determine the efficacy of the treatment with (CAP) on these effluents, thus obtaining very positive results. In the conclusions of these studies, published by Sciencedirect, a notable microbial reduction in exposures of (CAP) is observed at 120 seconds and total inactivation at 300 seconds.

The Cold Atmospheric Plasma technology experiences constant growth, therefore, its evolution and new applications do not stop advancing. Consequently, Plasmawise, an expert company in plasma technology, has made its own devices for the investigation of this type of treatment. The portable pWise plasma device is perfect for scientists who want to explore the most innovative techniques.
