GENERAL SYSTEM DESCRIPTION:
This SpectraPure
®
RODI System gives you a continuous supply of sparkling
clear water. The reliability with the SpectraPure
®
Water Treatment System is
greatly improved over other systems. Costly maintenance can be avoided,
providing high quality water at your fingertips.
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 plug up.
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
MaxCap
®
Extended Life Super DI cartridge and our SilicaBuster™ Extended
Life Super DI cartridge.
The MaxCap
®
Extended Life Super DI is used as a high-capacity “roughing”
cartridge and is followed by our SilicaBuster™ Extended Life Super
DI. Typically, if the RO water has 25 ppm TDS (Total Dissolved Solids)
entering a SilicaBuster™ DI cartridge alone, it might process about 266
gallons of pure DI water. By placing a MaxCap
®
DI cartridge in front
of the SilicaBuster™ cartridge, 800 gallons of water will pass through
both cartridges before the MaxCap
®
DI is exhausted. The SilicaBuster™
DI cartridge will be only one-third exhausted. A second MaxCap
®
DI will
process another 800 gallons and the SilicaBuster™ DI cartridge will now
be two-thirds exhausted. Only after a third Max Cap
®
DI cartridge processes
another 800 gallons should the SilicaBuster™ DI cartridge finally become
fully exhausted.
This example illustrates that three MaxCap
®
Super DI cartridges plus the
original SilicaBuster Super DI cartridge will process 2400 gallons of pure DI
water. It would have taken as many as ten standard mixed-bed cartridges
to produce the same amount of pure DI water.
