Claim 7:
8. A method comprising:
introducing a slurry having a fluid and solids onto a shaker, the shaker comprising a screen assembly, the screen assembly comprising:
a support structure comprising a frame, the support structure configured to and being coupled to the shaker, wherein the frame comprises an outer perimeter and at least one inner support member;
a continuous filtering surface affixed to the support structure, wherein the continuous filtering surface has a smooth surface, wherein the smooth surface is asymmetrical from a first end to a second end opposite the first end, the smooth surface comprising:
an erosion resistant region at the first end; and
a perforated region comprising perforations and extending between the erosion resistant region and the second end,

wherein the continuous filtering surface is a first filtering surface, and the screen assembly further comprises a second filtering surface affixed to the frame between the frame and the first filtering surface, and
wherein the first filtering surface and the second filtering surface are both affixed to an upper surface of the support structure; and

vibrating the continuous filtering surface to separate the fluid from the solids, such that the fluid on the continuous filtering surface passes through the perforations of the continuous filtering surface and the solids convey along the smooth surface of the continuous filtering surface.
