In an effort to assess the rate of organic P conversion or capture within an ATS™, HydroMentia conducted studies in which water samples were taken at intervals down an active floway at the S-154 MAPS facility. Noted in Figure 10 are these trends. From this data, it appears that organic P removal equals, and typically exceeds ortho P removal within the ATS™. The implication is that organic P hydrolysis, which generates ortho P, is occurring at a rate equal to or greater than ortho P uptake or precipitation. This provides strong indication that enzymatic activity is extensive within the ATS™. As this particular floway is harvested once weekly, it also appears that the enzyme-producing organisms are sustained on the actively managed floway. It is of course necessary to recognize that perhaps not all of the organic P removal may be associated with enzymatic activity, as particulate capture could also be involved. However, if there were no hydrolysis of organic P, it would be expected that ortho-P, not being replenished, would be reduced noticeably down the floway. This is not the case however, providing support to the probability that enzymatic activity is prevalent
