Yep that will work! If you can get centripetal flow (circular teacup effect) going in a circular tank you get the settleable solids to either go down the center drain or collect around it depending on your set up. I do the latter with my raised pastic tanks, and my center drain is connected to an external standpipe. I pull a knife valve twice a day to flush solids.
My suspended solids are sucked into my siphon and are trapped in the netting of my clarifier tank.
This is especially good with my tank I have outside next to the garden. The waste water is used to water the garden and the plants act like they're on steriods!
Did raft culture all last summer with tomatoes and tilapa using a diy yamabuki airlift to move the water. No water pump needed. Produced 200 tilapia for the table. I no longer do aquaponics as I prefer to concentrate on the fish culture.
