Diaphragm filtration system

摘要

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.
