Anthracite 90 is premium grade anthracite filter media with carbon content + 90%. Anthracite filter media promotes higher service flow rates and longer filter runs. Backwash rates are reduced as well. Low uniformity coefficient anthracite filter media extends the life of your filter, typically produces consistent improvements in turbidity removal, due in part to more
Efficient solids loading. Also, low uniformity coefficient media produces smaller changes in effluent turbidity during periods of peak influent turbidity.
