Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
58 words
A membrane system useful for filtering a fluid which contains particles to be removed from the fluid, the membrane system comprising two porous asymmetric membranes which comprise a skin side and an opposite side and which are arranged such that the skin side of one membrane is in intimate contact with the skin side of the other membrane.
Claim 2
Dependent Claim
58 words
A membrane system useful for filtering a fluid which contains particles to be removed from the fluid, the membrane system comprising two porous asymmetric membranes which comprise a skin side and an opposite side and which are arranged such that the skin side of one membrane is in intimate contact with the skin side of the other membrane.
Claim 3
Dependent Claim
22 words
A membrane system according to claim 1, in which the skin of each of the membranes has substantially the same pore size.
Claim 4
Dependent Claim
17 words
A membrane system according to claim 1 or 2, in which the membrane is a microporous membrane.
Claim 5
Dependent Claim
24 words
A membrane system according to any of claims 1 to 3, in which each of the membranes is made of polysulfone or aromatic polyamide.
Claim 6
Dependent Claim
38 words
A filtration system which comprises a membrane system according to any of claims 1 to 4, the membrane system being supported in the filtration system so that the whole of the fluid flow passes through the two membranes.
