Anthracite typically produces consistent improvements in turbidity removal because, in part, to more efficient solids loading. Low uniformity coefficient media also produces smaller changes in effluent turbidity during periods of peak influent turbidity. Our anthracite filter media is produced from the highest quality anthracite available to ensure the physical characteristics of hardness, durability and performance.
