How fuel treatment systems work
1. The tanks contain one or multiple filter coalescer elements
depending on the flow capacity. The separated water is heavier than the medium being pumped through and it collects in
a water container at the bottom of the tank.
2. Water droplets collect in the variably structured fibre bed
layers. The size of the droplets increases in the flow direction.
These droplets flow together to form a coherent water phase
which is removed. All solids are held back.
