5. The screen assembly of claim 1 further comprising
a first support beneath and supporting the first screen portion, and
a second support beneath and supporting the second screen portion.
6. The screen assembly of claim 1 further comprising
the at least one raised portion having two open ends.
7. The screen assembly of claim 6 wherein the open ends each have a plug therein.
8. The screen assembly of claim 6 wherein the at least one raised portion comprises two spaced-apart sides and the screen further comprising
at least one connection member connecting the sides of the at least one raised portion together.
9. The screen assembly of claim 8 wherein the at least one connection member is at least one strip across each of the open ends of the at least one raised portion.
10. The screen assembly of claim 1 further comprising
side hookstrips on the first screen portion for mounting the screen assembly in a basket.
11. The screen assembly of claim 1 wherein the at least one raised portion extends from a first end of the first screen portion at which a flow including fluid to be treated by the screen assembly is introduced onto the first screen portion to a second end of the first screen portion, the at least one raised portion extending across a width of the first screen portion.
12. The screen assembly of claim 1 wherein the at least one raised portion comprises two sides meeting at a top of the raised portion at an angle.
