I wish you luck finding a commercially available filtration system, suitable for high volume recirculating water like a splash pad, that will reliably remove pathogens.
A properly maintained (good luck!) DE filter might do the trick, but they’re messy enough that they’re banned in large parts of the country. Cartridge filters are usually rated at 10 microns, which is nowhere near good enough.
