Dometisc RO-1812-75 membrane elements are mainly applied to household water purifier and other water purifying devices in hospital and laboratory.
Membrane filters are usually manufactured as flat sheet stock or as hollow fibers and then
formed into on of several different types of membrane modules. Module construction typically
involves potting or sealing the membrane material into an assembly, such as with hollow-fiber
module. These types of modules are designed for long-term use over the course of a number of
years. Spiral-wound modules are also manufactured for long-term use, although these modules
are encased in a separate pressure vessel that is independent of the module itself.
Most hallow-fiber modules used in drinking water treatment applications are manufactured for
MF or UF membranes to filter particulate matter. These modules are comprised of hollow-fiber
membranes, which are long and very narrow tubes that may be constructed of membrane
materials described previously. The fibers may be bundled in one of several different
Fibers can be bundled together longitudinally, potted in a resin on both ends, and encased in a
pressure vessel. These modules are typically mounted vertically, although horizontal mounting
may be used. These fibers can be similar to spiral-wound modules and inserted into pressure
vessels independent of the module itself. These modules (and the pressure vessels) are mounted
horizontally. Bundled hollow fibers can also be vertically and submerged in a basin that does not
need a pressure vessel.
A typical hollow-fiber module may consist of several hundred to over 10,000 fibers. Although
dimensions vary by manufacturer, approximate ranges for hollow-fiber construction are:
• Outside diameter 0.5 – 2.0 mm
• Inside diameter 0.3-1.0 mm
• Fiber wall thickness 0.1-0.6 mm
• Fiber length 1-2 meters
Hollow-fiber membrane modules may operate in an “inside-out” or “outside-in” mode. In insideout
mode, feed water enters the center of the fiber (lumen) and is filtered radially through the
fiber wall. Filtrate is then collected from outside the fiber. During outside-in operation, feed
water passes from outside the fiber to the inside, where filtrate is collected in the center of the
