Filter System Flow Rates (Metric)

Filter System Flow Rates Metric
English

All filter media has optimum flow rates where that media will perform the best, and provide best filtration performance. This flow rate can be measured in the amount of liters per minute, or cubic meters per hour that can flow through one square meter of filter media square area. See the chart below for recommended values to use for common filter media.

Step 1 Enter the tank diameter in meters
Step 2 Enter the Service Flow Rate in Cubic Meters Per Hour
per square meter of tank surface area
Step 3 Enter Maximum Flow Rate Cubic Meters Per Hour
per square meter of tank surface area
Step 4 Enter Recommended Backwash Flow Rate Cubic Meters Per Hour
per square meter of tank surface area
Filter Tank Media Surface Area in Sq. Meters
Service Flow Rate Cubic Meters Per Hour
Maximum Flow Rate Cubic Meters Per Hour
Backwash Flow Rate Cubic Meters Per Hour
