designing a continuous sand filter
Upflow Sand Filter
Low Pressure Drop Upflow filter designs typically require two to three feet of driving head upstream of the filter. This design allows the majority of the captured solids to remain in the lower portion of the filter bed and removed from the filter very quickly. Consistent low headloss is normal for the UpFlow.
