Water Handbook - Filtration | SUEZ
The major advantages of dual-media filtration are higher rates and longer runs. Anthracite/sand/garnet beds have operated at normal rates of approximately 5 gpm/ft² and peak rates as high as 8 gpm/ft² without loss of effluent quality. CAPPING OF SAND FILTERS Rapid sand filters can be converted for mixed media operation to increase capacity by .
