ENVIRONTEC GF Gravel Filter is used for separating solid particles, dirt and collecting condensate water from biogas, and additionally used as a safety device against back flame. It is always installed after digesters or reactors.
EnvironTec gravel filter is designed as an air-tight double-chamber structure. The filter is equipped with a large amount of gravels, and there are an automatic condensate water collection and a drainage device at bottom. A maintenance opening for gravel discharge is provided.
The pressure gauges are installed in order to observe the variation of pressure. Normally the gravel filter should be flushed and cleaned when the differential pressure has reached 3~5mbar.
