1.1 General Information and Principles of Operation
These instructions give operating and maintenance details vital to the sustained
performance of the machine.
Reverse Osmosis (RO) is the removal of ionic, organic, and suspended
impurities from water by means of a membrane. Unlike a filter (“normal”
filtration), the feedwater or solution is separated into two streams by collecting
fluids from both sides of a pressurized membrane (“crossflow” filtration). A
semipermeable RO membrane, under sufficient pressure, allows passage of
purified water while rejecting and concentrating dissolved and suspended solids.
Mar Cor Purification manufactures a patented spiral-wound membrane package,
with a turbulent flow design. The membrane module (i.e. sepralator), also called
an element collects the purified water within a central tube (permeate tube), see
Figure 1.
Some operating definitions are provided to help you further understand your
machine:
PERMEATE RATE (PRODUCT WATER RATE) [QP]
This is the flow rate of purified water which has passed through the membrane
and out of the sepralator; expressed in gal/min (gpm) or gal/h (gph) [in metric,
liter/min (Lpm) or cubic meters/hour (m3/h). Specified permeate rates are
normally specified at 77°F (25°C).
