The vacuum collecting units that QUA-VAC can supply can be of the following executions with all the BIG advantages of QUA-VAC: flexible, simple, high quality and of course a low cost price.

Vacuum collecting unit for BLACK and GREY water

With this configuration you are able to collect the black water  from vacuum toilets (1.2 ltr per flush) and the grey water from showers, wash basins etc.The principal working of this unit is created by an ejector and an ejector/discharge pump. During discharge you have the possibility to create vacuum with the same pump. Using an electrical discharge valve, the pump will automatically discharge if high level in the tank is reached.






Easy Fit units for BLACK and GREY water
This equipment will be delivered as a fully mounted skid. The basic principle is the same as above collecting unit. The advantage of this unit is a rather short mounting period and the use of an excisting ships tank.This unit is perfect for refitting on board of excisting vessels.











Combined treatment unit for BLACK and GREY water

This unit has an integrated vacuum system. The vacuum is created by the ejector principle. One of the aeration chambers is used to build up the vacuum components. Sewage and grey water are treated biologically in chamber 1 and 2. Chamber 3 separates the remained solids and treated water will be disinfected inchamber 4. After treatment, the effluent meets all relevant requirements and can be discharged overboard.
