In order to compare the efficiency of different tower packings for purifying PCE-contaminated groundwater, the San Bernardino Water District tested a series of random packings in the same air stripper under identical conditions. As can be seen, 3.5" LANPAC showed better (lower) HTU than any other packing tested (including some smaller sized packings). Conclusion This design example based on the measured HTUs shows that using 3.5" LANPAC® allows a
