Can GMA GARNET be used in high-density water filtration systems?
GMA 30/60 is ideal for use as the finer grained layer in multi-media systems. The subangular to subrounded grains and the precise degree of sorting yield maximum surface area and permeability for efficient filtration with minimum backwash cycle times. In the United States garnet has been approved for use in this application by the National Sanitation Foundation. The toughness of the individual grains assures maximum time between replacement cycles and minimum operating cost.
