| FILTRATION SOLUTIONS is the sole Australian company to design and build equipment to utilise this unique filtration surface. These units can be used to remove solids from various process and waste streams from small to very large scale. They are of particular use in removal of carry over fines from thickeners or instead of thickeners in the mineral processing industry. They bring the benefits of membrane filtration to large scale industrial filters and combine the fine particle removal properties of membranes with the durability of high strength felts at equal or better flow rates. |

| The system uses expanded GORE-TEX® membrane filter cloths which can be shaped into tubular filters that act as liquid baghouses. Very fine solids are filtered to form an agglomerated cake on the surface of the membrane. In this type of filtration, differential pressure across the filter is limited to around 100 Kpa, and cake removal is by momentary flow reversal (pulsing), which takes only one to three seconds. Filtration starts almost immediately after pulsing and is virtually continuous. Suspended solids which have been consolidated into a cake during filtration settle rapidly to the bottom of the filter vessel where they are periodically discharged as a high density slurry. The objective of this mode of filtration is to operate at low filter pressures and short cake removal times. Because cake removal time may only be a few seconds filtration cycle times may be as short as four or five minutes and filter cakes as thin as 0.1 mm. The GORE-TEX® membrane filter cloths make this possible through their very fine pore size which permits surface filtration and their slippery surface which aids cake release. |
