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.
