Biogas filter

Biogas filter "FB ULTRA"

The biogas that is generated inside the anaerobic digesters and in landfills is saturated with water, it contains small solid particles in suspension, dust of elemental sulfur and other contaminants, consequently an efficient filtration is required before its use.


Failure to remove these impurities can in fact cause malfunctioning of devices and processes downstream of the filter, increasing maintenance costs and plant shutdowns.


Our FB ULTRA filter was designed by our team to ensure very high efficiency in the removal of pollutants and particulates.


This is possible thanks to the series housing of three different filter elements, each with its specific function.

Mode of operation

The gas enters the condensation collection tank through an internal pipe in the filter, where it spreads and begins to rise through the three filtering layers until it exits through the specific outlet.


The filter is equipped with a draining valve with suitable safety system to prevent the escape of biogas.

Technical specifications

The filter consists of a lower tank for collecting biogas condensation, which also acts as a hydraulic guard, and three filtration layers:


  • 1st LAYER composed of filling bodies with the job of trapping moisture and stopping the coarsest impurities;


  • 2st LAYER has the job of stopping the impurities passed through the filling bodies and any elemental sulphur dust resulting from biological desulphurisation;


  • 3st LAYER with the job of also capturing ammonia residues.
