DI
Cartridge Life (Vertical) as used in the Typhoon series: How many
gallons of water will the DI cartridge process?
Simple math can answer that question. The capacity of our vertical D.I. cartridge is 6,800 ppm. Take a moment to measure the TDS of the
water being produced by the reverse osmosis membrane . Divide that result
into 6800, the answer is very close to the number of gallons you can expect the D.I. cartridge to produce.The main differecnce will be due to the amount of TDS creep your set up suffers.
Example
TDS of water out of membrane 20 ppm
6,800
divided by 20 ppm = 340 gallons

Inline
DI cartridge as on Compact and Dual Home/Reef: How
many gallons of water will the DI process? It is simple math. The capacity of
the cartridge is 3,400 p.p.m. Measure the TDS of the water being produced by
the membrane. Divide that result into 3,400, the answer is very close to the
number of gallons you can expect to get from the DI cartridge.
Example TDS
of water out of membrane 20 ppm
3,400
divided by 20ppm = 170 gallons
