Why is media hardness important in filtration?

Media hardness is significant in filtration because it plays a crucial role in the physical integrity and longevity of the filtration media. Harder filter media can withstand the mechanical stresses that occur during the backwashing process without breaking down or degrading. When backwashing, the water flow causes turbulence that can exert shear forces on the media. If the media is too soft, it may break down into smaller particles, leading to reduced filtration efficiency and potential clogging of the filter system. Therefore, selecting filtration media with appropriate hardness ensures that it can endure these conditions and maintain effective performance over time.

While factors like water taste and temperature control are important in water treatment, they do not directly relate to the functionality and durability of filtration media in the context of backwashing. Similarly, the weight of the filter media, although it may play a role in handling and installation, does not influence its ability to effectively filter water or withstand backwashing forces.
