Protection of digestion towers and similar plants from excess or insufficient pressure with the help of a hydraulic seal

operational area | usage

Digester gas recovery/gas cleaning in:

  • Wastewater treatment plants with sludge recovery / digestion towers
  • Biogas plants
  • Industrial plants

product description

The hydraulic protection is installed in the gas dome or directly into a wall. The hydraulic seal within the stainless-steel tank separates the gas chamber from the atmosphere. The hydraulic seal is monitored by a sensor and responds to a low water level. This monitoring enables automatic water refilling. By varying the pipe diameters and lengths, almost any insufficiency or excess of pressures can be handled.
