Using Inclined Cascade Aeration to Strip Chlorinated VOCs From Drinking Water

Boyden, Brace H. / Banh, Duong T. / Huckabay, Houston K. / Fernandes, Joseph B.

Inclined cascade aeration (ICA) was effective in removing 10 chlorinated volatile organic chemicals (VOCs) from drinking water at liquid loadings of 5 gpm/ft (1.04 L s^–1/m) to 15 gpm/ft (3.1 L s^–1/m). Overall mass transfer (or desorption) coefficients (K_La_v) were an order of magnitude larger (0.08–0.54 s^–1) than those reported for packed‐tower aeration. A curve fit of the experimental data for all 10 VOCs with the equation K_La_v = 0.019 + 0.091 (Hp)^$f14(sin θ)^$, in which Hp is the Henry's law constant (atm) and θ is the angle of inclination, yielded desorption coefficients within ± 18 percent of experimental values. A cascade angle of 60° was found most efftcacious for compounds with Hp values >300 atm; compounds with Hp values <300 atm were most effectively stripped at yet steeper angles.
