Abstract: Systems and methods for filtering unpurified water using modular filtration units are disclosed. According some embodiments of the invention the modular filtration unit may include a modular removable filtration cartridge with pressed non-woven geotextile fabrics and a frame assembly, and a filtration container. The filtration container holds the modular removable filtration cartridges and has walls that form a basin. A first wall has an inlet for receiving water into the filtration container and a second wall has an outlet for draining water out of the filtration container. The water is filtered by the modular removable filtration cartridges as it flows across the basin from the inlet to the outlet. The modular filtration units may be combined together to form a zoned filtration assembly, which may be inserted into the hull of a floating swimming pool. The zoned filtration assemblies may filter natural water as it fills the swimming pool.
