摘要

A sanitary installation in which waste water is conveyed to a pipe system during the simultaneous supply of air. The pipe system includes a generally vertical long length of pipe which is closed at its upper end and open at its lower end. Waste water and air is introduced in the upper part of the pipe whereby air is separated and removed by means of a vacuum pump connected to the upper part of the pipe. Waste water is further collected in the form of a standing liquid column in the lower part of the vertical pipe and is successively caused to flow to a holding tank.
