Sewage sludge drying

Areas of application

Our industrial valves are used in critical locations:

  • Municipal wastewater treatment plants
  • Medium: Dewatered sewage sludge from sewage sludge drying,
    dry matter content approx. 25-28%.
  • Operating pressure: approx. 50 bar (pump PN 100)
  • Temperature: 20°C

Challenge and task

Our mission: to increase service life and overcome the disadvantages of conventional ball valves.

  • High seal wear due to deposits on the ball surface
  • Blockage of the valve after a few switching operations due to sludge in the dead spaces
  • Necessary operational downtime due to replacement, cleaning or inspection of the valve

Problem solution: GEFA DOMINO gate valve SD75 (AT750) DN150, PN100

We offer an effective solution by replacing ball valves with our reliable DOMINO knife gate valve AT750 DN150, PN100.
