The unit for ship sewage systems, with two ejectors Du100 mm, with electrified drain gate valves in the harness of each ejector, with a control panel, two pumps and a tank of 10 cubic metres. Vacuum wastewater collection unit of ejector type UV-ET AMM 1122-10.0 generates and maintains the required vacuum level in the pipelines of the wastewater and domestic water system by means of ejectors.
Wastewater and domestic water are collected in a collection tank of the unit. Pumps are used to pump the sewage and domestic water from the collection tank to the sewage storage tank of the ship.
The ejector creates a vacuum in the pipeline. When air and collected wastewater pass through the nozzle at high pressure, it causes a Venturi effect that draws wastewater from the inlet.
The wastewater then flows out of the ejector back into the collection tank. The operation of emptying the collection cistern is carried out manually or automatically.
