WebThe CT concept of ozone is expressed as a product of the average concentration of ozone (residual) multiplied by the time over which an organism is exposed to the residual. This product is referred to as CT and typically has the units mg-min/liter. This approach is conceptually the same as the lethality coefficient, but calculated in a somewhat ... WebThis value is a calculated value based on ozone concentration and feed-gas flow rate using this conversion: ((LPM x 60) x 0.001) x g/m3 = g/hr. As flow of fed-gas through the ozone generator increases, the g/hr ozone output will normally increase.
