CRYSTAL QUEST® Commercial multimedia systems are designed for the removal of turbidity in the water caused by sand, silt, ferric iron, oxidized manganese or sulfur. They are used in applications such as chlorination filtration systems, general turbidity removal and prior to ultraviolet sterilizers or water softeners.

Multi media filtration is a proven design concept; the coarse media layers in the top of the tank trap large particles, and smaller particles are trapped in the finer layers of media deeper in the filtering bed. The result is a highly efficient filtering, since removal takes place throughout the entire bed. Multi media filters typically remove particles 5 to 15 microns in size as opposed to a conventional single media sand filter which removes 30 micron or higher
