Abstract
A sewage treatment tank formed in upper and lower halves which engage each other along a parting line. The tank has an aeration chamber and an outlet chamber which are fluidly connected together at the bottom portion of the tank through an opening and also at the top portion of the tank at the fluid level by means of a surface skimmer. A tube settler is positioned in the outlet chamber and comprises a plurality of spaced and generally parallel plates each of which includes a plurality of spaced and generally parallel deflector members the surfaces of which are arranged at an acute angle to upward fluid flow in the outlet chamber. Holding members secure the plates in fixed position and have end portions held between the upper and lower halves of the tank at the parting line.
