I Claim:

1. A filter assembly comprising:

a funnel, open at top end and having tapered walls towards a flat bottom end, for holding a feed solution to be filtered, such that, after filtration, a filtrate exits the funnel through an outlet disposed on the bottom end of said funnel; and

a filter disposed at bottom end of the funnel and along the height of the funnel such that active surface of said filter is facing the walls of the funnel;

wherein the filter is so disposed as to minimise annular space between said filter and the narrowed walls at bottom end of said funnel, such that maximum feed solution is directed by the tapered walls to the filter, thereby reducing the quantity of remnant solution.

2. The assembly as claimed in claim 1, wherein said filter is a pleated filter.

3. The assembly as claimed in claim 1, wherein the side of the filter facing the top end of the funnel is capped in order to prevent feed solution from entering filter from said side.

4. The assembly as claimed in claim 1, wherein one or more filters are stacked in series to filter particles of smaller size.

5. The assembly as claimed in claim 1, wherein a vacuum pump is connected to said assembly to drive feed solution through the filter rapidly be reducing pressure drop across the filter.

6. The assembly as claimed in claim 1, wherein said assembly is connected in series with one or more different filter assemblies to perform a combination of filtering operations.

7. The assembly as claimed in claim 1, wherein said filter is integrated with one or more depth filters.

8. The assembly as claimed in claim 1, wherein there is a provision for said assembly to incorporate a further one or more diatomaceous earth (DE) filters.

9. The assembly as claimed in claim 1, wherein the funnel is connected to a filtrate container to collect the filtrate, through a tapered output connector.

10. The assembly as claimed in claim 1, wherein said assembly is easily and quickly replaceable in case of breakdown of one or more components of said assembly.
