Max. flow/pressure for upflow filter
Max. flow/pressure for upflow filter
(OP)
I am working with a system where wastewater enters into the bottom of a tank filled with activated carbon/sand (upflow filter). The tank is 10 ft diameter, 20 ft high. wastewater inflow into the tank is about 200 gpm.
We are going to increase the flow of the wastewater over the next year up to 500 gpm. I am worried about suspending the carbon/sand and washing it out as we increase the flow/pressure. How can I estimate the max. inflow rate/pressure that the filter can handle before the media
is suspended and washed out?
Any help would be appreciated.

There is 5 feet of water above the media before it spills off.

This will allow you to calculte how much the bed will expand at a given upflow rate.
