Abstract
A waste tank for a vacuum sewage system installed in a transport vehicle comprises a receptacle portion for receiving sewage up to a predetermined maximum filling level. The tank defines an inlet opening for admitting air and sewage to the tank and an outlet opening for exhausting air from the tank. The inlet and outlet openings are above the maximum filling level of the tank. The tank also comprises an inlet separator that separates air and sewage entering the tank by way of the inlet opening using the kinetic energy of the sewage, and thereby dissipates kinetic energy of the sewage so that sewage entering the receptacle portion of the tank does not do so in a violent fashion, such as to contribute to vigorous movement of the sewage or cause splashing.
