Wärtsilä Vacuum Toilets
Wärtsilä vacuum toilets use air to drive waste from the toilet to the treatment tank or intermediate collection tank. This contemporarily styled toilet has a built-in vacuum breaker and flush memory, is simple to install, and is supplied ready to connect. The control mechanism can be accessed without removing the bowl. By using only approximately 1 litre of water, the amount of wastewater is dramatically reduced.
Wärtsilä also offers a Vacuum Interface Valve, which provides an interface between the sewage collection system and conventional grey water drains and urinals. The valve enables an easy connection to gravity-based appliances, enabling cost savings and effective integration with the vacuum system piping. The valve is reliable, easy to maintain, and has been installed in USN/USCG ships and merchant marine vessels throughout the world.
