- 1 - ABSTRACT OF THE DISCLOSURE There is provided a sewage treatment apparatus particularly intended for marine use where the apparatus is subject to tilting as a result of pitching and rolling of the ship. The apparatus includes an oxidation tank having a sewage liquor outlet incorporating a discharge weir. This weir is disposed at the centre of a horizontal plane across the interior of the tank and containing the discharge weir, so that the above tilting of the tank substantially does not affect the rate of sewage liquor discharge and therefore substantially does not result in surging in the flow of sewage liquor from the oxidation tank to a settlement chamber. Such surging could adversely affect the maintenance of quiescent conditions in the settlement chamber. The settlement chamber is substantially fully enclosed and has a clarified liquid outlet incorporating an upstanding discharge weir presented coaxially by a top wall of the chamber. The chamber is operatively maintained substantially full, and since the free surface area of the sewage liquor in the chamber is minimized the above tilting of the chamber likewise does not adversely affect the maintenance of substantially quiescent conditions within the chamber.
