How much is 1 part per billion? You win the lottery of $10 million and find a penny on the way to the bank.
The penny is one part per billion (1 ppb).
DOWEX MARATHON C sodium form has 2.0 eq/L capacity. Therefore a cubic foot of DOWEX
MARATHON C sodium contains 2.87 lb of sodium ions. One liter contains 46 g of sodium ions. If the resin
were in the barium form, it would contain 8.57 lb of barium ions at full loading (137 g/L resin).
A standard 5 ft 3 fiber drum weighs 15 lb (6.8 kg) and is 30 in. (76 cm) high with a 20.5-in. (52-cm)
diameter.
A standard wood pallet weighs approximately 30 lb (13.6 kg).
At 20���
1 cubic foot of water weighs 62.4 lb
1 gallon of water weighs 8.33 lb
1 cubic centimeter of water weighs 1 gram
1 liter of water weighs 1 kilogram
1 cubic meter of water weighs 1 metric ton
1 metric ton = 2240 lb
For a column with a diameter of:
1 in. diameter = 154 mL of resin per foot of height
2 in. diameter = 617 mL of resin per foot of height
3 cm diameter = 7 mL of resin per cm of height
4 cm diameter = 12.6 mL of resin per cm of height
1 gpm is 525,600 gal per year
1 gpm for one year with 1 ppm is 4.31 lb per year
100 m 3 /h is 876,000 m 3 per year
100 m 3 /h for one year with 1 ppm is 876 kg per year
