Abstract
A diaphragm filtration system includes a pipe and a filtering diaphragm supported substantially coaxially within the pipe and lying, at least indirectly, tightly against the inner pipe wall as filtration proceeds in a radially outward direction. The diaphragm is a sheet member bent cylindrically and having overlapping surfaces; the cross section of the diaphragm is an annulus having a non-continuous area and overlapping ends.
Claims3
In a diaphragm filtration system including a pipe;
- a filtering diaphragm supported substantially coaxially within the pipe and lying, at least indirectly, tightly against the inner pipe wall as filtration proceeds in a radially outward direction;
- the improvement wherein said diaphragm is a sheet member bent cylindrically and having liquid impervious, unbonded overlapping surfaces;
- the cross section of said diaphragm being an annulus having overlapping ends and a non-continuous area and the end-to-end circumference of said diaphragm being greater than the circumference of said inner pipe wall.
