In a cylonic incinerator for burning liquid and solid wastes, one or more scraper bars are suspended by a non-rigid suspension from support arms projecting from a vertical driven shaft, so as to spread and disturb the waste on the floor of the incinerator.

Incinerator

A sewage treatment apparatus of the activated sludge extended aeration type, particularly for use on board ships, comprises an inverted cone-shaped settling tank extending downwardly into an aerating tank. Sewage entering the aerating tank is constrained to flow around the outside of the settling tank, during which time it is aerated. The aerated liquid is then transferred to the settling tank, where sludge settling to the bottom thereof is removed and fed back to the aerating tank. An outlet means for removing treated liquid from just below the liquid surface in the settling tank is disposed at the center of said tank.
