GENERAL SYSTEM DESCRIPTION:
The incoming feed water from a cold water source is directed through
BLACK tubing with an inline ball valve and is first passed through a
sediment prefilter. This filter is used to remove excessive turbidity, sand,
dust, silt, etc., that would otherwise cause the carbon filter to become
fouled. The next stage of filtration is the carbon block prefilter. This filter
is used to remove organics and chlorine from the feed water that can
damage the membrane. The next stage of the system is the RO membrane.
Household water pressure is used to force tap water through the
semipermeable RO membrane. The membrane only allows the purest of
water molecules to pass through it while over 98% of
most inorganic salts,
all microorganisms and almost all high molecular weight organics in the
water
are rejected by the membrane and sent down the drain.
These RODI systems have two stages of Deionization that polish the RO
water to less than one ppm purity.
The fourth and fifth stage filters are our
Mega MaxCap™ DI Cartridge and our Enduro DI™ High-Performance DI
Finishing Cartridge.
The Mega MaxCap™ DI Cartridge is used as a high-capacity “roughing”
cartridge and is followed by our Enduro DI™ high-performance finishing
cartridge. The Mega MaxCap™ DI cartridge has a much higher capacity,
but less purity than the Enduro DI™ cartridge. These DI cartridges work
in tandem to achieve a greatly extended lifespan when compared to
standard mixed-bed DI cartridges. Because the RO water reaches it first,
the Mega MaxCap™ will need to be replaced more often than the Enduro
DI™.
The Mega MaxCap
™
RODI system comes equipped with two Dual-Probe
Inline TDS meters for complete monitoring of water purity throughout
every stage of the purification process. The left-side TDS meter will monitor
the tap water TDS and the TDS of the RO water, allowing you to accurately
compute the rejection rate of the RO membrane. (See “Testing The Quality
Of The Membrane” on Page 15.) The right-side meter monitors the DI
cartridges to let you know when they need to be replaced. It will also
monitor the purity of your product water when set to the “Out” position.
