High Capacity
This cartridge (catalog no. D0803) has the
capacity to remove 113 grams (1740 grains) of
dissolved ionized impurities (as NaCl) to an
endpoint of 50,000 ohm-cm. This high capacity
configuration produces water with an electrical
resistivity of about 175,000 ohm-cm. Each
cartridge will purify about 660 liters (175
gallons) of water containing 170 mg/liter (10
grains/gallon, as NaCl). The pressure drop
across the cartridge is less than 7 kPa (about 1
psig) at 38 L/hr (10 GPH) when the cartridge is
new.
Ultrapure (Mixed Resin)
This cartridge (catalog no. D0809) has the
capacity to remove 65 grams (750 grains) of
dissolved ionized impurities (as NaCl). About
3/4 (75%) of the capacity is capable of
producing water with an electrical resistivity
greater than 1 megohm/cm. Each cartridge will
purify about 380 liters (about 100 gallons) of
water containing 170 mg/liter (10 grains/gallon,
as NaCl) to 20,000 ohms. The pH is 6.8 to 7.2,
and the water produced is largely free of silica.
The water is also free of CO
2
until exposed to
atmosphere. The pressure drop across the
cartridge is less than 7 kPa (about 1 psig) at 38
L/hr. (10 GPH) when the cartridge is new.
