Plant revamping in Potenza

The pre-existing PFR (Plug Flow Reactor) type plant, simplified and fuelled by pig manure slurry, was initially analysed to assess the effective functioning state and define the most suitable revamping activities to be undertaken, in detail.

Here below are details of the main activities carried out:

  • Functional updating of the digester tankFunctional updating of the thermo-hydraulic system: installation of a sludge recirculation system (for digester mixing and fluxing) and a heat exchanger outside the reactor tank
  • Functional updating of the thermo-hydraulic system: installation of a sludge recirculation system (for digester mixing and fluxing) and a heat exchanger outside the reactor tank
  • Design and installation of an automation system: design and installation of an electric control panel fitted with PLC, operating panel and GSM modem; installation of liquid waste capacity measurer; installation of biogas capacity measurer as well as methane and hydrogen sulphate concentration sensors; construction of compressed air plant to power pneumatic valves
  • The creation of two new chemical dosing ranges, for the pretreatment of biogas and hydrogen sulphate reduction

Plant fuelled by: floated pig manure slurry
Installed electrical power: 30 kW​
