Coarse #8-12 (1.5 mm) Garnet water treatment media available from Watts. For use as the lower (final) filtration layer of down flow multi-bed filtration systems with other medias such as Pyrolox, Calcite, Sand, Greensand, or Birm. The advantage of multi-bed filtration systems lies with a common issue with single-bed systems. In these systems, the smallest particles that are intended to be the last stage in the filtration process rise to the top of the filter bed after backwash. Therefore, when water enters the system, the largest sediment particles are being captured by the smallest contaminants forcing a choked, caked layer in the first few inches of the filter bed. The end result is ineffective and frustratingly slow water filtration.

To keep the larger particles at the top and the smaller particles at the bottom after backwash, multi-bed filtration systems use different water treatment medias with different densities and gravities. Garnet is ideal for this sort of filtration because it has a high density and high hardness for fantastic durability. Garnet is chemically static, non-metallic, and can be found in nature. Its high density makes Garnet require higher flow rates but it also allows Garnet to be heavier than other media its size. When used correctly, multi-media filtration systems can go through long periods of backwash while maintaining inverse gradation and superior water treatment performance.
