High rate trickling filters
Did you know?
WebWhat are the design considerations for tricking filters? These are classified as high rate or low rate, based on organic and hydraulic loading applied to the unit. How to design trickling filters? In most cases, empirical relationships are used to determine the required filter volume for a given degree of wastewater treatment. WebThe normal hydraulic loading rate ranges for standard rate and high rate trickling filters are: Standard rate: 25 to 100 gpd/sq ft or 1 to 40 MGD/acre; High rate: 100 to 1000 gpd/sq ft or 4 to 40 MGD/acre . If the hydraulic loading rate for a particular trickling filter is too low, septic conditions will begin to develop. Example 1:
