GENERAL INFORMATION
The biological treatment systems require that the sewage should remain, in various stages of treatment, in large volume tanks. While the sewage is staying in the tanks, sedimentation and flotation processes, respectively, allow the deposit of substances concentrated on the bottom or their ascent toward the free surface. In addition, the shapes of these tanks depend on the choice of the purification process and on the morphological requirements of the installation site.
Since its foundation, Siderurgica del Polesine has designed and built any kind of solution for the collection of sedimentary and floated.
For illustrative purposes we list below some of the thousands of solutions that we achieved.
Each machine is carefully designed and built, based on the needs of our customer by optimizing the choices of materials, construction types, collection systems.
For any requests, our technical and sales department will offer you the solution.
