The present disclosure relates to a vacuum filter (100) that incorporates a large area pleated filter element (102) having pleated hydrophilic membrane configured along slanting surface in pyramid shape and incorporated with in a filter housing (110) that can be accommodated in neck of a filtrate container (124). The disclosed configuration reduces overall height of the filtering system improving its stability and reducing space requirement. Further, top portion of the filter housing is configured to receive either a feed cup (122) for direct feeding of feed liquid by pouring in the cup or a fitting with tube that can be used to suck the feed from a feed solution container under action of a vacuum thus allowing universal use. In another embodiment, a single hydrophobic membrane (122) is provided to avoid problems of low flow due to bubbles coming with the feed solution and also to allow restart of filtration without air lock. |
