vessel must be sized to ensure laminar or streamline flow; turbulent flow causes remixing. An example of this sizing method in a decanter is contained in Case Study 2, see page 12. In order to settle fine droplets and ensure laminar flow, large vessels and long residence times are required. It may take five, ten, and or even thirty minutes to

Backwash and Flow Rates of Filter Media – Pure Water ...

The amount of flow and the amount needed to backwash the media are determined by the surface area of the media—depending on the tank diameter—not on the total area (cubic feet) of media.. A 12" diameter filter tank supports considerably greater gpm (gallons per minute) flow than a 10" diameter tank, but it also requires considerably more backwash water.
