Borghetto S. Spirito Wastewater Treatment Plant

Expansion of MBR lines

As part of the intervention, the following works have been implemented:


Water line

  • Installation of pump #1 with a flow rate of 240 l/s and a head of 45 m on the connecting piping to the DN 700 duct made of spheroidal cast iron, length 300 meters
  • Fine screening with rotary drum technology and transport and compaction auger, spacing 2 mm – 1 line – flow rate 1,200 cubic meters per hour for the grid.
  • Installation of 18 cassettes with 48 modules of MBR ultrafiltration, including modifications to the piping of existing lines and connection of the new lines.
  • Expansion of the reagent system for MBR (citric acid and sodium hypochlorite lines).


Sludge line

  • Aerobic stabilization – electromechanical setup of 1 line – total volume 1240 cubic meters.
  • Thickening – machinery setup of 1 line – total volume 350 cubic meters.
  • Duplication of mechanical dewatering lines on centrifuges provided by the Client.
