There are several potential sources of malodors in a marine waste treatment system.

Rinse with sea water – If the toilet uses seawater to rinse, the death and subsequent decomposition of microscopic marine organisms will occur in the water intake circuit, which may cause bad odors, particularly when the toilet has not been rinsed for a long time.

Our VacuFlush systems, thanks to rinsing with fresh water, eliminate this phenomenon.

Odor Permeation in the Discharge Hose – If a discharge hose has been installed allowing waste to accumulate in a poorly drained section, decomposition of this waste may occur; The foul odor caused by this process is capable of permeating the hose material (rubber hoses can be particularly vulnerable).

To determine if this is the source of the odor, rub the suspicious areas with a clean cloth. Smell the cloth frequently: Where odor molecules have permeated the hose, the smell will transfer to the cloth.

The defective hose section will have to be replaced. If it is impossible to replace the hose in order to restore correct drainage, replace the hose with a rigid PVC pipe.

Designed for hose circuits, the hose SeaLand® OdorSafe® It is 16 times more effective against odor permeation than other hoses on the market; It is the best choice for a waste treatment hose.

Ventilation Circuit – An incorrect installation of the ventilation circuit sometimes causes the existence of low points that can accumulate liquids and prevent the escape of gases. A better design of the ventilation circuit and hose route can solve the problem.

When flushing a toilet, effluent entering the storage tank pushes foul-smelling gases out of the tank, through the vent loop, and out the hull vents. For

eliminate odors before they go outside the boat, it is recommended to install a SaniGard™ filter . The carbon filter absorbs heavy odor molecules; one filter will be enough for an entire sailing season.
