Abstract
A device for the treatment of an influent with a porous media. The influent passes radially through the porous media and into an internal volume of the device. The treated influent then passes through an open check valve in the internal volume, and then to downstream equipment. During a backwash operation, a backwash fluid is passed into the internal volume of the device in a direction to close the check valve. The blocked path in the internal volume of the device causes the backwash fluid to pass radially outwardly into the porous media and fluidize the same.
