To-and-fro bridge with pumps

The to-and-fro bridge with pump has the function of extracting the material (sludge, sand, etc.) on the bottom of the tank through the pumps and of conveying it to a reinforced concrete discharge channel. Hence, the residues are extracted with a system not supplied by Friulana Costruzioni. At the same time, the foaming blades convey the suspended solids (light and oily material) to the discharge hopper. The clean water flows into the pipe through a series of holes to a discharge channel. At the same time, the spillway pipe cleaning device removes the deposits from the pipes (using Nylon brushes).
