Filtration removes the particles that chemistry cannot. Clarity, water use, and the size of the mechanical room all follow from the filter type chosen. Sand filters are simple and common; regenerative media filters trade a more involved operating routine for very fine filtration, smaller footprint, and far less backwash water.
FreyTech has supplied and installed Defender regenerative media filters at New York facilities including Ithaca College's 50-meter pool and Fairport High School, and represents Filtrex regenerative media filters, Mer-Made commercial sand filter systems and strainers, and WAPOTECH deep-bed filters. Filtration changes are mechanical-room projects: they involve hydraulics, turnover requirements under New York code, plan approval, and coordination with controls.

Selection considerations
New York code sets turnover requirements by pool type; the filter must handle design flow with the engineer's sign-off.
Regenerative media filters need periodic media changes and a bump cycle; staff must be trained for them.
Quantify current backwash volume and heating loss before projecting savings.
Filter changes typically require engineer-prepared plans and health-department approval (6-1.8).
