Description

technical field

[0001] The present invention relates to a method of controlling the vacuum generator and thus the vacuum level in a vacuum drainage system, and in particular to the control of one or more liquid ring screw pumps in a system comprising, in addition to the generator, a pump connected to the vacuum generator One or more tubular collectors or suction lines and one or more toilets, urinals, gray water drains, etc. connected to the suction line. Background technique

[0002] Vacuum drainage systems of the type described above are common and are often used on ships, aircraft and trains. However, on land, such systems are also increasingly used, mainly because of the low water consumption, ease of operation and simple treatment of waste water, and the benefits achieved by such systems. Flexible system in terms of pipe installation.

[0003] The applicant of the present application introduced a new vacuum drainage system in European Patent 0287350 of 1987, in which ...
