Salt (Ionic) Rejection
Salt (Ionic) Rejection is the percent of dissolved salt rejected by the
membrane, calculated from an average concentration over the
membrane.
Salt (Ionic) Passage
Salt (Ionic) Passage is the percent of dissolved salts passed
through the membrane.
Primary Pressure (P
p
)
Primary Pressure (P
p
) is the pressure between the pump discharge
and the feed port of the first membrane element housing.
Final Pressure (P
f
)
Final Pressure (P
f
) is the pressure between the concentrate outlet
of the last housing and the concentrate valve.
Pre-filter Pressure (P
pre
)
Pre-filter Pressure (P
pre
) is the water pressure entering the pre-filter.
Post-filter Pressure (P
post
)
Post-filter Pressure (P
post
) is the water pressure leaving the pre-
filter.
Membrane Elements
Membrane elements are the key to reverse osmosis. Interleaved
layers of semipermeable membrane, spacer and permeate carrier
spiraled around a central permeate tube make up the element. The
spacer allows for movement of the concentrate past the membrane,
and the permeate carrier carries the pure water out of the
membrane element. The elements that Mar Cor Purification uses
are spiral-wound membrane elements with a turbulent flow design.
The membrane element collects the permeate water within the
central tube, called the permeate tube.
