A solid, fiberglass-reinforced plastic rotary drum filter includes a first solid fiberglass-reinforced head at one end and a second solid fiberglass-reinforced head at the other end. A central solid fiberglass-reinforced plastic pipe extends from one plastic head a predetermined distance into the plastic drum. A plurality of radial, solid fiberglass-reinforced plastic drainage conduits extends from the solid fiberglass-reinforced plastic deck of the plastic drum to the central pipe. The longitudinal separation between the radial plastic drainage conduits and the first plastic head is carefully chosen and the dimensions of the first plastic head are such that the first plastic head is strong enough to withstand the head-bending force due to radial force, drive torque, and hydraulic end force. |
