Giải thích
Gravity grease interceptors are large in-ground tanks with a typical minimum liquid capacity of 750 gallons, sized upward based on the drainage load (DFU or seating). Their large volume and long retention time let grease float and settle before the effluent leaves. Small hydromechanical units serve lower-flow applications instead.
