Water Handbook Filtration SUEZ

At ambient temperature the recommended filter backwash rate is 68 gpmft for anthracite and 1315 gpmft for sand Anthracite filters associated with hot process softeners require a backwash rate of 1215 gpmft because the water is less dense at elevated operating temperatures Cold water should not be used to backwash a hot process filter
