PAL Green Division was responsible for modifications on the sludge line of a civil waste water treatment plant in Grosseto. In particular, it has built a hub for the delivery and treatment of all biological sludge produced. The plant is divided into two parts, each with specific functions.

• The first section dealing with the management, accumulation and disposal of dehydrated sludge basically stores the sludge, handles the milling/ accumulation for an adequate period of time and fills the trucks fitted with disposal skips. The process is conceived along no. 2 parallel lines, capable of containing approx. 80 m3 material each, for a grand total of 160sqm. I The two containment silos are made of vitrified steel, to avoid oxidation phenomena related to the aggressiveness of the contents and to facilitate maintenance, cleaning and sanitising operations, and have a diameter of 4 metres. Each silo is equipped with a sliding frame extractor with an AISI 304 stainless steel hydraulic piston with a fixed capacity of 50 square metres per hour. The silos are loaded via 3 chain conveyors.

Second section for the intake of solid sludge from other smaller plants. The process is conceived on 2 parallel lines, each capable of holding about 60sqm of material, for a grand total of 120sqm.
