The filter media in a Leopold® filter — media quality, bed composition, bed depth, and grain size distribution — is designed according to filter configuration, raw water quality, pretreatment, and desired filtrate quality. Leopold® filters employ Engineered Filter Media® anthracite, the lowest uniformity coefficient (UC) anthracite filter media available. Leopold® Engineered Filter Media® anthracite typically produces consistent improvements in turbidity removal due, in part, to more efficient solids loading. Plus, low-UC media produces smaller changes in effluent turbidity during periods of peak influent turbidity.

Leopold readily supplies a full scope of media for filter designs. In addition to filter anthracite in all sizes and UCs, Leopold can provide:

• Silica support gravel
• Silica filtration sand
• High-density support gravel
• High-density filtration sand
• Manganese greensand
• Granular activated carbon (GAC)
