Fuel Polishing Filters for Diesel & Biodiesel
As diesel gets older a fine sediment and gum forms in the diesel brought about by the reaction of diesel components with oxygen from the air. The fine sediment and gum will block fuel filters, leading to fuel starvation and engine stopping.
Frequent filter changes are then required to keep the engine going. The gums and sediment do not burn in the engine very well and can lead to carbon and soot deposits on injectors and other combustion surfaces.
The presence of water allows for growth of fungus and bacteria, these produce natural by-products such as organic acids which make the fuel unstable. This problem is compounded in biodiesel which is more hygroscopic (water absorbing) as compared to Diesel.
Establishing a system for filtering the contents of the main storage tank through a recirculating filter system can keep contaminant build up in check. This can be made automatic and will reduce the potential for problems by removing sediment and gums. The filters should be changed and checked at regular intervals.
Siga Filtration can supply bag filter housings in the following configuration for effective filtration of diesel and biodiesel.
-Single bag filter housings
-Duplex bag filter housings in duty/standby arrangement (for uninterrupted flow)
-3 x Bag filter housings in series for staged filtration e.g. 100 micron followed by 50 micron followed by 5 or 1 micron filtration
-Mobile filter skids with castors or fork lift channels for ease of installation
