Abstract The purpose of this study was to compare the performance of four gas/liquid contactors. These systems can be adapted to the buffer tanks of public swimming pools to extract, by stripping, the trichloramine present in re-circulated water of pools. Work was carried out on a pilot scale, enabling several parameters to be varied. The results confirmed the satisfactory levels of extraction that were found during full-scale trials, where up over 60% reductions in concentration of atmospheric trichloramine achieved, and enabled the determination of the design parameters for each system. An example of design calculations for these four systems for a typical buffer tank is included.
