One of the most important challenges of the industries, in general, is to be able to meet the requirements that the administration demands for the wastewater discharges as a product of its industrial activity.
This was one of the issues raised by Congelados Navarra, one of the largest producers of frozen vegetables and a reference in the sector in Europe.
A company that has maintained an important sustained growth during the last years, with a consolidated national and international expansion plan, which has led them to obtain a growing need of extension and improvement in the wastewater treatment facilities of their different production centers.
On the other hand, Congelados Navarra has planned, within its strategic objective of continuous improvement and optimization of resources, to carry out a program of evaluation of the manufacturing processes in such a way that water consumption per unit produced has been reduced.
One of the most important challenges, in terms of the environment and water treatment, that the company faced was that of its main plant in Fustiñana (Navarra).
The frozen food company needed its facilities to comfortably comply with the new requirements requested by the administration and, also, with the lowest possible energy consumption, sludge generation, and environmental impact.
The technological solution that has been installed is a combined process of Anaerobic Treatment RANC, followed by the Aerobic process called Sigma FBR (Flotation Biological Reactor).
