Biogas filters

One of the biogas conditioning system element is filtration. Type of the filter depends on filter location. In our offer there are two kinds of biogas filters – polypropylene filters and fine mat filters.
Filters are located mainly in process rooms near to digesters, in containers or underground concrete wells/ chambers.

POLYPROPYLENE FILTERS

Polypropylene filters (also gravel filters) are used for foam and condensate arresting which are taken out from anaerobic reactors/ digesters and driven to biogas network. They are located near anaerobic reactors / digesters, but also often mounted as an additional equipment of gasholders.

Polypropylene filters are mostly mounted in underground concrete chambers at the lowest point in biogas network.

Polypropylene filters are equipped with automatic condensate overflow, internal dividers which force biogas flow direction, cut-off valves, manholes and measurement pipes.

Polypropylene filters are completely made of stainless steel.

FINE MAT FILTERS

Fine mat filters are used to catch sludge particles and small pollutants which can be driven out from digesters. Fine mat filters are located before pressure increasing devices or before biogas combustion devices.

Material responsible for biogas treatment is special fine mat that stops particles which can cause malfunction of propellers or burners.

Polypropylene filters are completely made of stainless steel.
