    RMF Volume Limitations

    Guys,

    Trying to understand some basics about RMF (Defender, Nemato) vs. sand filtration for commercial pools. Obviously for the larger volume aquatic centers RMF can have some nice payback qualities despite the expensive upfront cost, but I'm trying to figure out a lower bound where the payback here still makes sense. Have you guys seen any good payback analyses and/or know if there's a threshold on volume where, once crossed, an RMF system actually becomes cost inefficient? I'm assuming the hypothetical pool is open 365 days a year. Thanks in advance!

    Welcome to the forum.

    The vast majority of us are residential pool owners and have no idea what RMF is......at least, I don't.

    It's essentially the same type of filter as a Hayward ec-65. It's a de filter designed to be "bumped" to redistribute the de. Commercial applications are more complex and probably outside the scope of this forum. The basic principle works for some applications.
