Gravel filter GFR - PURIFY
Description
The gas removed from biogas digestion or fermentation units can be heavily contaminated with foam particles, various particulate matter and water vapour. A pre-filtration of the gas (often adequate enough) can be achieved with the use of an ennox gravel filter. The gas flows through the ennox gravel filter layer where large particulate matter and water vapour is left behind. The water collects at the bottom of the filter where it can be drained with a siphon assembly. Following heavy contamination of the gravel filter the spraying unit can be used for rinsing, avoiding the need for opening the digester unit. As an option a gravel removal opening can be installed.

Bio or sewage gas is saturated with water vapour. Condensation can occur within the pipework systems of digester systems as a result of fluctuating temperatures. The ennox condensate pot allows for the collection and controlled discharge of any condensation water accumulations. The gas flows through the condensate pot where it is channeled within the pot through a separation chamber. The reduction in gas flow velocity and the influence of temperature fluctuations cause the water vapour in the gas to condense and collect at the bottom of the pot. The collected condensate can be discharged from the point of collection either with a siphon or an automatic discharger.

Gas from bio or sewage processing systems are often contaminated with water vapour or very sparsely distributed small particulate matter, which, when used for example in CHP units can cause operating problems or even damage. For the fine cleaning of the gases before utilization an ennox ceramic fine filter is used. In the ennox ceramic fine filter the fine particles contained in the gas are captured by a special fire-clay filter (Pantel). Condensate collects in the form of a moisture layer on the surface of the material and drips into the collector below. An automatic discharge system with level indication can be installed in the base of the digester upon request.

Biogas, sewage gas and landfill gas contains not only water vapour but also a whole host of additional impurities such as hydrogen sulphide, NH3 and siloxane, which, when processed in the utilization system can not only lead to a reduction in efficiency, but also result in damage to the system. The dehumidification of the gas before processing is a basic preliminary requirement in order to permit an efficient usage of the biogas and an investment in the sustainability of the utilization system. With the ennox gas chill dryer the gas to be processed is passed through a heat exchanger where the cooled gas can expel any moisture which drips and is collected as condensate. According to the technical requirements of the installation a post-warming or an economical and ecological energy recovery system can be implemented into the system.
