    5/28/2018

    A year long pilot study was performed at an indoor commercial pool in Geauga County Ohio. The testing included an extensive evaluation of common and widely available granular filtration medias and compared the performance results in real time. The intent of the study was firstly to compare the real time turbidity removal capabilities of the various medias and secondly assess the removal ability of cryptosporidium sized particulate (2-5 micron). This assessment also included a polystyrene microsphere challenge on selected well-seasoned medias to compare the ability of the medias to remove crypto sized particles.
